Drug Interactions (FDA Label)
Drug Interactions Inhibitors of CYP3A4 and CYP2D6 The concomitant use of hydrocodone bitartrate and ibuprofen tablets and CYP3A4 inhibitors, such as macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g. ketoconazole), protease inhibitors (e.g., ritonavir), can increase the plasma concentration of hydrocodone, resulting in increased or prolonged opioid effects. These effects could be more pronounced with concomitant use of hydrocodone bitartrate and ibuprofen tablets and CYP2D6 and CYP3A4 inhibitors, particularly when an inhibitor is added after a stable dose of hydrocodone bitartrate and ibuprofen tablets are achieved (see WARNINGS: Risks of Concomitant Use or Discontinuation of Cytochrome P450 3A4 Inhibitors and Inducers ). After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the hydrocodone plasma concentration will decrease (see CLINICAL PHARMACOLOGY: Pharmacokinetics ), resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to Hydrocodone Bitartrate and Ibuprofen Tablets. If concomitant use is necessary, consider dosage reduction of hydrocodone bitartrate and ibuprofen tablets until stable drug effects are achieved. Evaluate patients at frequent intervals for respiratory depression and sedation. If a CYP3A4 inhibitor is discontinued, consider a dosage increase of hydrocodone bitartrate and ibuprofen tablets until stable drug effects are achieved. Evaluate for signs of opioid withdrawal. CYP3A4 Inducers The concomitant use of hydrocodone bitartrate and ibuprofen tablets and CYP3A4 inducers, such as rifampin, carbamazepine, and phenytoin, can decrease the plasma concentration of hydrocodone (see CLINICAL PHARMACOLOGY: Pharmacokinetics ), resulting in decreased efficacy or onset of a withdrawal syndrome in patients who have developed physical dependence to hydrocodone (see WARNINGS: Withdrawal ). After stopping a CYP3A4 inducer, as the effects of the inducer decline, the hydrocodone plasma concentration will increase (see CLINICAL PHARMACOLOGY: Pharmacokinetics ), which could increase or prolong both the therapeutic effects and adverse reactions, and may cause serious respiratory depression. If concomitant use is necessary, consider a dosage increase of hydrocodone bitartrate and ibuprofen tablets until stable drug effects are achieved. Evaluate for signs of opioid withdrawal. If a CYP3A4 inducer is discontinued, consider hydrocodone bitartrate and ibuprofen tablets dosage reduction and evaluate patients at frequent intervals for signs of respiratory depression and sedation. Benzodiazepines and Other Central Nervous System (CNS)
Depressants
Due to additive pharmacologic effect, the concomitant use of benzodiazepines and other CNS depressants, such as benzodiazepines and other sedative hypnotics, anxiolytics, and tranquilizers, muscle relaxants, general anesthetics, antipsychotics, gabapentinoids (gabapentin or pregabalin) and other opioids, including alcohol, can increase the risk of hypotension, respiratory depression, profound sedation, coma, and death. Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Inform patients and caregivers of this potential interaction, educate them on the signs and symptoms of respiratory depression (including sedation). If concomitant use is warranted, consider recommending or prescribing an opioid overdose reversal agent [see WARNINGS, DOSAGE AND ADMINISTRATION].
Serotonergic Drugs
The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system, such as selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), triptans, 5-HT3 receptor antagonists, drugs that effect the serotonin neurotransmitter system (e.g., mirtazapine, trazodone, tramadol), certain muscle relaxants (i.e., cyclobenzaprine,metaxalone), and monoamine oxidase (MAO) inhibitors (those intended to treat psychiatric disorders and also others, such as linezolid and intravenous methylene blue), has resulted in serotonin syndrome (see PRECAUTIONS: Information for Patients ). If concomitant use is warranted, frequently evaluate the patient, particularly during treatment initiation and dose adjustment. Discontinue hydrocodone bitartrate and ibuprofen tablets if serotonin syndrome is suspected.
Monoamine Oxidase
Inhibitors (MAOIs) MAOI interactions with opioids may manifest as serotonin syndrome or opioid toxicity (e.g., respiratory depression, coma). If urgent use of an opioid is necessary with MAOIs such as phenelzine, tranylcypromine, linezolid, use test doses and frequent titration of small doses to treat pain while closely monitoring blood pressure and signs and symptoms of CNS and respiratory depression. The use of hydrocodone bitartrate and ibuprofen tablets are not recommended for patients taking MAOIs or within 14 days of stopping such treatment.
Mixed
Agonist/Antagonist and Partial Agonist Opioid Analgesics Agonist/antagonist analgesics such as pentazocine, nalbuphine, butorphanol and buprenorphine may reduce the analgesic effect of hydrocodone bitartrate and ibuprofen tablets and/or precipitate withdrawal symptoms in these patients. Avoid concomitant use of these drugs.
Muscle Relaxants Hydrocodone
Bitartrate and Ibuprofen Tablets may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increased degree of respiratory depression. Because respiratory depression may be greater than otherwise expected, decrease the dosage of hydrocodone bitartrate and ibuprofen tablets and/or the muscle relaxant as necessary. Due to the risk of respiratory depression with concomitant use of skeletal muscle relaxants and opioids, consider recommending or prescribing an opioid overdose reversal agent (see WARNINGS, DOSAGE AND ADMINISTRATION). Examples: Cyclobenzaprine, metaxalone.
Anticholinergics
The concomitant use of anticholinergic drugs may increase risk of urinary retention and/or severe constipation, which may lead to paralytic ileus. Evaluate patients for signs of urinary retention or reduced gastric motility when hydrocodone bitartrate and ibuprofen tablets are used concomitantly with anticholinergic drugs.
Drugs That Interfere With Hemostasis
Ibuprofen and anticoagulants such as warfarin have a synergistic effect on bleeding. The concomitant use of ibuprofen and anticoagulants have an increased risk of serious bleeding compared to the use of either drug alone. Serotonin release by platelets plays an important role in hemostasis. Case-control and cohort epidemiological studies showed that concomitant use of drugs that interfere with serotonin reuptake and an NSAID may potentiate the risk of bleeding more than an NSAID alone. Monitor patients with concomitant use of hydrocodone bitartrate and ibuprofen tablets with anticoagulants (e.g., warfarin), antiplatelet agents (e.g., aspirin), SSRIs, and SNRIs for signs of bleeding (see WARNINGS: Hematologic Toxicity ).
Aspirin
Pharmacodynamic studies have demonstrated interference with the antiplatelet activity of aspirin when ibuprofen 400 mg, given three times daily, is administered with enteric coated low-dose aspirin. The interaction exists even following a once-daily regimen of ibuprofen 400 mg, particularly when ibuprofen is dosed prior to aspirin. The interaction is alleviated if immediate-release low-dose aspirin is dosed at least 2 hours prior to a once daily regimen of ibuprofen; however, this finding cannot be extended to enteric-coated low-dose aspirin [see Clinical Pharmacology/Pharmacodynamics ]. Because there may be an increased risk of cardiovascular events due to the interference of ibuprofen with the antiplatelet effect of aspirin, for patients taking low-dose aspirin for cardioprotection who require analgesics, consider use of an NSAID that does not interfere with the antiplatelet effect of aspirin, or non-NSAID analgesics, where appropriate. Controlled clinical studies showed that the concomitant use of NSAIDs and analgesic doses of aspirin does not produce any greater therapeutic effect than the use of NSAIDs alone. In a clinical study, the concomitant use of an NSAID and aspirin was associated with a significantly increased incidence of GI adverse reactions as compared to use of the NSAID alone (see WARNINGS: Gastrointestinal Bleeding, Ulceration, and Perforation ). Concomitant use of hydrocodone bitartrate and ibuprofen tablets and analgesic doses of aspirin is not generally recommended because of the increased risk of bleeding (see WARNINGS: Hematologic Toxicity ). ACE-Inhibitors, Angiotensin Receptor Blockers, and Beta-blockers NSAIDs may diminish the antihypertensive effect of angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), or beta-blockers (including propranolol). During concomitant use of hydrocodone bitartrate and ibuprofen tablets and ACE-inhibitors, ARBs, or beta-blockers, monitor blood pressure to ensure that the desired blood pressure is obtained. In patients who are elderly, volume-depleted (including those on diuretic therapy), or have renal impairment, co-administration of an NSAID with ACE inhibitors or ARBs may result in deterioration of renal function, including possible acute renal failure. Evaluate for signs of worsening renal function (see WARNINGS: Renal Toxicity and Hyperkalemia ). These effects are usually reversible. When these drugs are administered concomitantly, patients should be adequately hydrated. Assess renal function at the beginning of the concomitant treatment and periodically thereafter.
Diuretics
Clinical studies, as well as post-marketing observations, showed that NSAIDs reduced the natriuretic effect of loop diuretics (e.g., furosemide) and thiazide diuretics in some patients. This effect has been attributed to the NSAID inhibition of renal prostaglandin synthesis. During concomitant use of hydrocodone bitartrate and ibuprofen tablets with diuretics, observe patients for signs of worsening renal function, in addition to assuring diuretic efficacy including antihypertensive effects (see WARNINGS: Renal Toxicity and Hyperkalemia ).
Digoxin
The concomitant use of ibuprofen with digoxin has been reported to increase the serum concentration and prolong the half-life of digoxin. During concomitant use of hydrocodone bitartrate and ibuprofen tablets and digoxin, monitor serum digoxin levels. Lithium NSAIDs have produced elevations in plasma lithium concentration and reductions in renal lithium clearance. The mean minimum lithium concentration increased 15%, and the renal clearance decreased by approximately 20%. This effect has been attributed to NSAID inhibition of renal prostaglandin synthesis. During concomitant use of hydrocodone bitartrate and ibuprofen tablets and lithium, evaluate patients for signs of lithium toxicity.
Methotrexate
Concomitant use of NSAIDs and methotrexate may increase the risk for methotrexate toxicity (e.g., neutropenia, thrombocytopenia, renal dysfunction). During concomitant use of hydrocodone bitartrate and ibuprofen tablets and methotrexate, evaluate patients for methotrexate toxicity.
Cyclosporine
Concomitant use of hydrocodone bitartrate and ibuprofen tablets and cyclosporine may increase cyclosporine’s nephrotoxicity. During concomitant use of hydrocodone bitartrate and ibuprofen tablets and cyclosporine, evaluate patients for signs of worsening renal function. NSAIDs and Salicylates Concomitant use of ibuprofen with other NSAIDs or salicylates (e.g., diflunisal, salsalate) increases the risk of GI toxicity, with little or no increase in efficacy (see WARNINGS: Gastrointestinal Bleeding, Ulceration, and Perforation). The concomitant use of ibuprofen with other NSAIDs or salicylates is not recommended.
Pemetrexed
Concomitant use of hydrocodone bitartrate and ibuprofen tablets and Pemetrexed may increase the risk of Pemetrexed associated myelosuppression, renal, and GI toxicity (see the Pemetrexed prescribing information). During concomitant use of hydrocodone bitartrate and ibuprofen tablets and Pemetrexed, in patients with renal impairment whose creatinine clearance ranges from 45 to 79 mL/min, monitor for myelosuppression, renal and GI toxicity. NSAIDs with short elimination half-lives (e.g., diclofenac, indomethacin) should be avoided for a period of two days before, the day of, and two days following administration of Pemetrexed. In the absence of data regarding potential interaction between Pemetrexed and NSAIDs with longer half-lives (e.g., meloxicam, nabumetone), patients taking these NSAIDs should interrupt dosing for at least five days before, the day of, and two days following Pemetrexed administration.
Contraindications
CONTRAINDICATIONS Hydrocodone bitartrate and ibuprofen tablets are contraindicated in patients with: Significant respiratory depression (see WARNINGS: Life-Threatening Respiratory Depression ) . Acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment (see WARNINGS: Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients ) . Known or suspected gastrointestinal obstruction, including paralytic ileus (see WARNINGS: Risks of Use in Patients with Gastrointestinal Conditions ) . Known hypersensitivity (e.g., anaphylactic reactions, serious skin reactions) to hydrocodone, ibuprofen, or any components of the drug product (see WARNINGS: Anaphylactic Reactions, Serious Skin Reactions ) . Patients known to be hypersensitive to other opioids may exhibit cross-sensitivity to hydrocodone. History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs. Severe, sometimes fatal, anaphylactic reactions to NSAIDs have been reported in such patients (see WARNINGS: Anaphylactic Reactions, Exacerbation of Asthma Related to Aspirin Sensitivity ) . In the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS: Cardiovascular Thrombotic Events ) .
Related Warnings
AND PRECAUTIONS Opioid-Induced Hyperalgesia and Allodynia: Opioid-Induced Hyperalgesia (OIH) occurs when an opioid analgesic paradoxically causes an increase in pain, or an increase in sensitivity to pain. If OIH is suspected, carefully consider appropriately decreasing the dose of the current opioid analgesic, or opioid rotation. ( 5.7 ) Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients : Regularly evaluate, particularly during initiation and titration. ( 5.8 )
Adrenal
Insufficiency : If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off of the opioid. ( 5.9 )
Severe
Hypotension : Regularly evaluate during dosage initiation and titration. Avoid use of hydrocodone bitartrate extended-release tablets in patients with circulatory shock. ( 5.10 ) QTc Prolongation : Avoid use in patients with congenital long QTc syndrome. In patients who develop QTc prolongation, consider reducing the dose. ( 5.11 , 12.2 ) Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness : Monitor for sedation and respiratory depression. Avoid use of hydrocodone bitartrate extended-release tablets in patients with circulatory shock. ( 5.12 ) Risk of Obstruction in Patients who have Difficulty Swallowing or have Underlying GI Disorders that may Predispose them to Obstruction : Consider use of an alternative analgesic. ( 5.14 )
5.1 Addiction, Abuse, and Misuse Hydrocodone bitartrate extended-release tablets contain hydrocodone, a Schedule II controlled substance. As an opioid, hydrocodone bitartrate extended-release tablets expose users to the risks of addiction, abuse, and misuse. Because extended-release products such as hydrocodone bitartrate extended-release tablets deliver the opioid over an extended period of time, there is a greater risk for overdose and death due to the larger amount of hydrocodone present <span class="opacity-50 text-xs">[see Drug Abuse and Dependence ( 9 )]</span>. Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed hydrocodone bitartrate extended-release tablets. Addiction can occur at recommended doses and if the drug is misused or abused. Assess each patient’s risk for opioid addiction, abuse, or misuse prior to prescribing hydrocodone bitartrate extended-release tablets, and reassess all patients receiving hydrocodone bitartrate extended-release tablets for the development of these behaviors and conditions. Risks are increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depression). The potential for these risks should not, however, prevent the prescribing of hydrocodone bitartrate extended-release tablets for the proper management of pain in any given patient. Patients at increased risk may be prescribed opioids such as hydrocodone bitartrate extended-release tablets, but use in such patients necessitates intensive counseling about the risks and proper use of hydrocodone bitartrate extended-release tablets along with frequent reevaluation for signs of addiction, abuse, and misuse. Consider prescribing naloxone for the emergency treatment of opioid overdose <span class="opacity-50 text-xs">[see Dosage and Administration ( 2.2 ), Warnings and Precautions ( 5.2 )]</span>. Abuse or misuse of hydrocodone bitartrate extended-release tablets by crushing, chewing, snorting, or injecting the dissolved product will result in the uncontrolled delivery of the hydrocodone and can result in overdose and death <span class="opacity-50 text-xs">[see Drug Abuse and Dependence ( 9.2 ), and Overdosage ( 10 )]</span> . Opioids are sought for nonmedical use and are subject to diversion from legitimate prescribed use. Consider these risks when prescribing or dispensing hydrocodone bitartrate extended-release tablets. Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity and advising the patient on careful storage of the drug during the course of treatment and the proper disposal of unused drug. Contact local state professional licensing board or state-controlled substances authority for information on how to prevent and detect abuse or diversion of this product.
5.2 Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression has been reported with the use of opioids, even when used as recommended. Respiratory depression, if not immediately recognized and treated, may lead to respiratory arrest and death. Management of respiratory depression may include close observation, supportive measures, and use of opioid antagonists, depending on the patient’s clinical status <span class="opacity-50 text-xs">[see Overdosage ( 10 )]</span> . Carbon dioxide (CO 2 ) retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids. While serious, life-threatening, or fatal respiratory depression can occur at any time during the use of hydrocodone bitartrate extended-release tablets, the risk is greatest during the initiation of therapy or following a dosage increase. To reduce the risk of respiratory depression, proper dosing and titration of hydrocodone bitartrate extended-release tablets are essential <span class="opacity-50 text-xs">[see Dosage and Administration ( 2.1 , 2.3 )]</span> . Overestimating the hydrocodone bitartrate extended-release tablets dosage when converting patients from another opioid product can result in fatal overdose with the first dose. Accidental ingestion of even one dose of hydrocodone bitartrate extended-release tablets, especially by children, can result in respiratory depression and death due to an overdose of hydrocodone. Educate patients and caregivers on how to recognize respiratory depression and emphasize the importance of calling 911 or getting emergency medical help right away in the event of a known or suspected overdose. Opioids can cause sleep-related breathing disorders including central sleep apnea (CSA) and sleep-related hypoxemia. Opioid use increases the risk of CSA in a dose-dependent fashion. In patients who present with CSA, consider decreasing the opioid dosage using best practices for opioid taper <span class="opacity-50 text-xs">[see Dosage and Administration ( 2.4 )]</span> .
Patient
Access to Naloxone for the Emergency Treatment of Opioid Overdose: Discuss the availability of naloxone for the emergency treatment of opioid overdose with the patient and caregiver and assess the potential need for access to naloxone, both when initiating and renewing treatment with hydrocodone bitartrate extended-release tablets. Inform patients and caregivers about the various ways to obtain naloxone as permitted by individual state naloxone dispensing and prescribing requirements or guidelines (e.g., by prescription, directly from a pharmacist, or as part of a community-based program). Educate patients and caregivers on how to recognize respiratory depression and emphasize the importance of calling 911 or getting emergency medical help, even if naloxone is administered. Consider prescribing naloxone, based on the patient’s risk factors for overdose, such as concomitant use of CNS depressants, a history of opioid use disorder, or prior opioid overdose. The presence of risk factors for overdose should not prevent the proper management of pain in any given patient. Also consider prescribing naloxone if the patient has household members (including children) or other close contacts at risk for accidental ingestion or overdose. If naloxone is prescribed, educate patients and caregivers on how to treat with naloxone [see Dosage and Administration ( 2.2 ), Warnings and Precautions ( 5.1 , 5.3 ), Overdosage ( 10 )].
5.3 Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants Profound sedation, respiratory depression, coma, and death may result from the concomitant use of hydrocodone bitartrate extended-release tablets with benzodiazepines and/or other CNS depressants, including alcohol (e.g., non-benzodiazepine sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids). Because of these risks, reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Observational studies have demonstrated that concomitant use of opioid analgesics and benzodiazepines increases the risk of drug-related mortality compared to use of opioid analgesics alone. Because of similar pharmacological properties, it is reasonable to expect similar risk with the concomitant use of other CNS depressant drugs with opioid analgesics [ see Drug Interactions ( 7 )] . If the decision is made to prescribe a benzodiazepine or other CNS depressant concomitantly with an opioid analgesic, prescribe the lowest effective dosages and minimum durations of concomitant use. In patients already receiving an opioid analgesic, prescribe a lower initial dose of the benzodiazepine or other CNS depressant than indicated in the absence of an opioid, and titrate based on clinical response. If an opioid analgesic is initiated in a patient already taking a benzodiazepine or other CNS depressant, prescribe a lower initial dose of the opioid analgesic, and titrate based on clinical response. Inform patients and caregivers of this potential interaction and educate them on the signs and symptoms of respiratory depression (including sedation). If concomitant use is warranted, consider prescribing naloxone for the emergency treatment of opioid overdose <span class="opacity-50 text-xs">[see Dosage and Administration ( 2.2 ), Warnings and Precautions ( 5.2 ), Overdosage ( 10 ) ]</span>. Advise both patients and caregivers about the risks of respiratory depression and sedation when hydrocodone bitartrate extended-release tablets are used with benzodiazepines or other CNS depressants (including alcohol and illicit drugs). Advise patients not to drive or operate heavy machinery until the effects of concomitant use of the benzodiazepine or other CNS depressant have been determined. Screen patients for risk of substance use disorders, including opioid abuse and misuse, and warn them of the risk for overdose and death associated with the use of additional CNS depressants including alcohol and illicit drugs <span class="opacity-50 text-xs">[see Drug Interactions ( 7 )]</span> .
5.4 Neonatal Opioid Withdrawal Syndrome Use of hydrocodone bitartrate extended-release tablets for an extended period of time during pregnancy can result in withdrawal in the neonate. Neonatal opioid withdrawal syndrome, unlike opioid withdrawal syndrome in adults, may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. Observe newborns for signs of neonatal opioid withdrawal syndrome and manage accordingly. Advise pregnant women using opioids for an extended period of time of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available <span class="opacity-50 text-xs">[see Use in Specific Populations ( 8.1 )]</span> .
5.5 Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS) To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse, and misuse, the Food and Drug Administration (FDA) has required a Risk Evaluation and Mitigation Strategy (REMS) for these products. Under the requirements of the REMS, drug companies with approved opioid analgesic products must make REMS-compliant education programs available to healthcare providers. Healthcare providers are strongly encouraged to do all of the following: Complete a REMS-compliant education program offered by an accredited provider of continuing education (CE) or another education program that includes all the elements of the FDA Education Blueprint for Health Care Providers Involved in the Management or Support of Patients with Pain. Discuss the safe use, serious risks, and proper storage and disposal of opioid analgesics with patients and/or their caregivers every time these medicines are prescribed.
The Patient Counseling
Guide (PCG) can be obtained at this link: www.fda.gov/OpioidAnalgesicREMSPCG. Emphasize to patients and their caregivers the importance of reading the Medication Guide that they will receive from their pharmacist every time an opioid analgesic is dispensed to them. Consider using other tools to improve patient, household, and community safety, such as patient-prescriber agreements that reinforce patient-prescriber responsibilities. To obtain further information on the opioid analgesic REMS and for a list of accredited REMS CME/CE, call 1-800-503-0784, or log on to www.opioidanalgesicrems.com. The FDA Blueprint can be found at www.fda.gov/OpioidAnalgesicREMSBlueprint
5.6 Risks of Concomitant Use or Discontinuation of Cytochrome P450 3A4 Inhibitors and Inducers Concomitant use of hydrocodone bitartrate extended-release tablets with a CYP3A4 inhibitor, such as macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g., ketoconazole), and protease inhibitors (e.g., ritonavir), may increase plasma concentrations of hydrocodone and prolong opioid adverse reactions, which may cause potentially fatal respiratory depression <span class="opacity-50 text-xs">[see Warnings and Precautions ( 5.2 )]</span> , particularly when an inhibitor is added after a stable dose of hydrocodone bitartrate extended-release tablets are achieved. Similarly, discontinuation of a CYP3A4 inducer, such as rifampin, carbamazepine, and phenytoin, in hydrocodone bitartrate extended-release tablet-treated patients may increase hydrocodone plasma concentrations and prolong opioid adverse reactions. When using hydrocodone bitartrate extended-release tablets with CYP3A4 inhibitors or discontinuing CYP3A4 inducers in hydrocodone bitartrate extended-release tablet-treated patients, evaluate patients at frequent intervals and consider dosage reduction of hydrocodone bitartrate extended-release tablets until stable drug effects are achieved <span class="opacity-50 text-xs">[see Drug Interactions ( 7 ) ]</span> . Concomitant use of hydrocodone bitartrate extended-release tablets with CYP3A4 inducers or discontinuation of an CYP3A4 inhibitor could decrease hydrocodone plasma concentrations, decrease opioid efficacy or, possibly, lead to a withdrawal syndrome in a patient who had developed physical dependence to hydrocodone. When using hydrocodone bitartrate extended-release tablets with CYP3A4 inducers or discontinuing CYP3A4 inhibitors, monitor patients closely at frequent intervals and consider increasing the opioid dosage if needed to maintain adequate analgesia or if symptoms of opioid withdrawal occur <span class="opacity-50 text-xs">[see Drug Interactions ( 7 )]</span> .
5.7 Opioid-Induced Hyperalgesia and Allodynia Opioid-Induced Hyperalgesia (OIH) occurs when an opioid analgesic paradoxically causes an increase in pain, or an increase in sensitivity to pain. This condition differs from tolerance, which is the need for increasing doses of opioids to maintain a defined effect <span class="opacity-50 text-xs">[see Dependence ( 9.3 )]</span> . Symptoms of OIH include (but may not be limited to) increased levels of pain upon opioid dosage increase, decreased levels of pain upon opioid dosage decrease, or pain from ordinarily non-painful stimuli (allodynia). These symptoms may suggest OIH only if there is no evidence of underlying disease progression, opioid tolerance, opioid withdrawal, or addictive behavior. Cases of OIH have been reported, both with short-term and longer-term use of opioid analgesics. Though the mechanism of OIH is not fully understood, multiple biochemical pathways have been implicated. Medical literature suggests a strong biologic plausibility between opioid analgesics and OIH and allodynia. If a patient is suspected to be experiencing OIH, carefully consider appropriately decreasing the dose of the current opioid analgesic, or opioid rotation (safely switching the patient to a different opioid moiety) <span class="opacity-50 text-xs">[see Dosage and Administration ( 2.7 ), Warnings and Precautions ( 5.16 )]</span>.
5.8 Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients The use of hydrocodone bitartrate extended-release tablets in patients with acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment is contraindicated. Patients with Chronic Pulmonary Disease : Hydrocodone bitartrate extended-release tablet-treated patients with significant chronic obstructive pulmonary disease or cor pulmonale, and those with a substantially decreased respiratory reserve, hypoxia, hypercapnia, or pre-existing respiratory depression are at increased risk of decreased respiratory drive including apnea, even at recommended dosages of hydrocodone bitartrate extended-release tablets <span class="opacity-50 text-xs">[see Warnings and Precautions ( 5.2 )]</span> . Elderly, Cachectic, or Debilitated Patients: Life-threatening respiratory depression is more likely to occur in elderly, cachectic, or debilitated patients because they may have altered pharmacokinetics or altered clearance compared to younger, healthier patients <span class="opacity-50 text-xs">[see Warnings and Precautions ( 5.3 )]</span> . Regularly evaluate patients, particularly when initiating and titrating hydrocodone bitartrate extended-release tablets and when hydrocodone bitartrate extended-release tablets are given concomitantly with other drugs that depress respiration <span class="opacity-50 text-xs">[see Warnings and Precautions ( 5.2 , 5.3 ), Drug Interactions ( 7 )]</span> . Alternatively, consider the use of non-opioid analgesics in these patients.
5.9 Adrenal Insufficiency Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. Presentation of adrenal insufficiency may include non-specific symptoms and signs including nausea, vomiting, anorexia, fatigue, weakness, dizziness, and low blood pressure. If adrenal insufficiency is suspected, confirm the diagnosis with diagnostic testing as soon as possible. If adrenal insufficiency is diagnosed, treat with physiologic replacement doses of corticosteroids. Wean the patient off of the opioid to allow adrenal function to recover and continue corticosteroid treatment until adrenal function recovers. Other opioids may be tried as some cases reported use of a different opioid without recurrence of adrenal insufficiency. The information available does not identify any particular opioids as being more likely to be associated with adrenal insufficiency.
5.10 Severe Hypotension Hydrocodone bitartrate extended-release tablets may cause severe hypotension including orthostatic hypotension and syncope in ambulatory patients. There is an increased risk in patients whose ability to maintain blood pressure has already been compromised by a reduced blood volume, or after concurrent administration of certain CNS depressant drugs (e.g., phenothiazines or general anesthetics) <span class="opacity-50 text-xs">[see Drug Interactions ( 7 )]</span> . Regularly evaluate these patients for signs of hypotension after initiating or titrating the dosage of hydrocodone bitartrate extended-release tablets. In patients with circulatory shock, hydrocodone bitartrate extended-release tablets may cause vasodilation that can further reduce cardiac output and blood pressure. Avoid the use of hydrocodone bitartrate extended-release tablets in patients with circulatory shock.
5.11 QTc Interval Prolongation QTc prolongation has been observed with hydrocodone bitartrate extended-release tablets following daily doses of 160 mg <span class="opacity-50 text-xs">[see Clinical Pharmacology ( 12.2 )]</span> . This observation should be considered in making clinical decisions regarding patient monitoring when prescribing hydrocodone bitartrate extended-release tablets in patients with congestive heart failure, bradyarrhythmias, electrolyte abnormalities, or who are taking medications that are known to prolong the QTc interval. Hydrocodone bitartrate extended-release tablets should be avoided in patients with congenital long QT syndrome. In patients who develop QTc prolongation, consider reducing the dose by 33% to 50%, or changing to an alternate analgesic.
5.12 Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness In patients who may be susceptible to the intracranial effects of CO 2 retention (e.g., those with evidence of increased intracranial pressure or brain tumors), hydrocodone bitartrate extended-release tablets may reduce respiratory drive, and the resultant CO 2 retention can further increase intracranial pressure. Monitor such patients for signs of sedation and respiratory depression, particularly when initiating therapy with hydrocodone bitartrate extended-release tablets. Opioids may also obscure the clinical course in a patient with a head injury. Avoid the use of hydrocodone bitartrate extended-release tablets in patients with impaired consciousness or coma.
5.13 Gastrointestinal Obstruction, Dysphagia, and Choking In the clinical studies with specific instructions to take hydrocodone bitartrate extended-release tablets with adequate water to swallow the tablet, 11 out of 2,476 subjects reported difficulty swallowing hydrocodone bitartrate extended-release tablets. These reports included esophageal obstruction, dysphagia, and choking, one of which had required medical intervention to remove the tablet <span class="opacity-50 text-xs">[see Adverse Reactions ( 6 )]</span> . Instruct patients not to pre-soak, lick, or otherwise wet hydrocodone bitartrate extended-release tablets prior to placing in the mouth, and to take one tablet at a time with enough water to ensure complete swallowing immediately after placing in the mouth. Patients with underlying gastrointestinal disorders such as esophageal cancer or colon cancer with a small gastrointestinal lumen are at greater risk of developing these complications. Consider use of an alternative analgesic in patients who have difficulty swallowing and patients at risk for underlying gastrointestinal disorders resulting in a small gastrointestinal lumen. Pediatric patients may be at increased risk of esophageal obstruction, dysphagia, and choking because of a smaller gastrointestinal lumen if they ingest hydrocodone bitartrate extended-release tablets <span class="opacity-50 text-xs">[see Use in Specific Populations ( 8.4 )]</span> .
5.14 Risks of Use in Patients with Gastrointestinal Conditions Hydrocodone bitartrate extended-release tablets are contraindicated in patients with known or suspected gastrointestinal obstruction, including paralytic ileus. The hydrocodone in hydrocodone bitartrate extended-release tablets may cause spasm of the sphincter of Oddi. Opioids may cause increases in serum amylase. Regularly evaluate patients with biliary tract disease, including acute pancreatitis, for worsening symptoms.
5.15 Increased Risk of Seizures in Patients with Seizure Disorders The hydrocodone in hydrocodone bitartrate extended-release tablets may increase the frequency of seizures in patients with seizure disorders, and may increase the risk of seizures occurring in other clinical settings associated with seizures. Regularly evaluate patients with a history of seizure disorders for worsened seizure control during hydrocodone bitartrate extended-release tablet therapy.
5.16 Withdrawal Do not abruptly discontinue hydrocodone bitartrate extended-release tablets in a patient physically dependent on opioids. When discontinuing hydrocodone bitartrate extended-release tablets in a physically dependent patient, gradually taper the dosage. Rapid tapering of hydrocodone in a patient physically dependent on opioids may lead to a withdrawal syndrome and return of pain <span class="opacity-50 text-xs">[see Dosage and Administration ( 2.7 ), Drug Abuse and Dependence ( 9.3 )]</span> . Additionally, avoid the use of mixed agonist/antagonist analgesics (e.g., pentazocine, nalbuphine, and butorphanol) or partial agonist (e.g., buprenorphine) analgesics in patients who are receiving a full opioid agonist analgesic, including hydrocodone bitartrate extended-release tablets. In these patients, mixed agonist/antagonist and partial agonist analgesics may reduce the analgesic effect and/or may precipitate withdrawal symptoms <span class="opacity-50 text-xs">[see Drug Interactions ( 7 )]</span> .
5.17 Risks of Driving and Operating Machinery Hydrocodone bitartrate extended-release tablets may impair the mental and physical abilities needed to perform potentially hazardous activities such as driving a car or operating machinery. Peak blood levels of hydrocodone may occur 14 to 16 hours (range 6 to 30 hours) after initial dosing of hydrocodone bitartrate extended-release tablet administration. Blood levels of hydrocodone, in some patients, may be high at the end of 24 hours after repeated-dose administration. Warn patients not to drive or operate dangerous machinery unless they are tolerant to the effects of hydrocodone bitartrate extended-release tablets and know how they will react to the medication.
5.1 Addiction, Abuse, and Misuse Hydrocodone bitartrate extended-release tablets contain hydrocodone, a Schedule II controlled substance. As an opioid, hydrocodone bitartrate extended-release tablets expose users to the risks of addiction, abuse, and misuse. Because extended-release products such as hydrocodone bitartrate extended-release tablets deliver the opioid over an extended period of time, there is a greater risk for overdose and death due to the larger amount of hydrocodone present <span class="opacity-50 text-xs">[see Drug Abuse and Dependence ( 9 )]</span>. Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed hydrocodone bitartrate extended-release tablets. Addiction can occur at recommended doses and if the drug is misused or abused. Assess each patient’s risk for opioid addiction, abuse, or misuse prior to prescribing hydrocodone bitartrate extended-release tablets, and reassess all patients receiving hydrocodone bitartrate extended-release tablets for the development of these behaviors and conditions. Risks are increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depression). The potential for these risks should not, however, prevent the prescribing of hydrocodone bitartrate extended-release tablets for the proper management of pain in any given patient. Patients at increased risk may be prescribed opioids such as hydrocodone bitartrate extended-release tablets, but use in such patients necessitates intensive counseling about the risks and proper use of hydrocodone bitartrate extended-release tablets along with frequent reevaluation for signs of addiction, abuse, and misuse. Consider prescribing naloxone for the emergency treatment of opioid overdose <span class="opacity-50 text-xs">[see Dosage and Administration ( 2.2 ), Warnings and Precautions ( 5.2 )]</span>. Abuse or misuse of hydrocodone bitartrate extended-release tablets by crushing, chewing, snorting, or injecting the dissolved product will result in the uncontrolled delivery of the hydrocodone and can result in overdose and death <span class="opacity-50 text-xs">[see Drug Abuse and Dependence ( 9.2 ), and Overdosage ( 10 )]</span> . Opioids are sought for nonmedical use and are subject to diversion from legitimate prescribed use. Consider these risks when prescribing or dispensing hydrocodone bitartrate extended-release tablets. Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity and advising the patient on careful storage of the drug during the course of treatment and the proper disposal of unused drug. Contact local state professional licensing board or state-controlled substances authority for information on how to prevent and detect abuse or diversion of this product.
5.2 Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression has been reported with the use of opioids, even when used as recommended. Respiratory depression, if not immediately recognized and treated, may lead to respiratory arrest and death. Management of respiratory depression may include close observation, supportive measures, and use of opioid antagonists, depending on the patient’s clinical status <span class="opacity-50 text-xs">[see Overdosage ( 10 )]</span> . Carbon dioxide (CO 2 ) retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids. While serious, life-threatening, or fatal respiratory depression can occur at any time during the use of hydrocodone bitartrate extended-release tablets, the risk is greatest during the initiation of therapy or following a dosage increase. To reduce the risk of respiratory depression, proper dosing and titration of hydrocodone bitartrate extended-release tablets are essential <span class="opacity-50 text-xs">[see Dosage and Administration ( 2.1 , 2.3 )]</span> . Overestimating the hydrocodone bitartrate extended-release tablets dosage when converting patients from another opioid product can result in fatal overdose with the first dose. Accidental ingestion of even one dose of hydrocodone bitartrate extended-release tablets, especially by children, can result in respiratory depression and death due to an overdose of hydrocodone. Educate patients and caregivers on how to recognize respiratory depression and emphasize the importance of calling 911 or getting emergency medical help right away in the event of a known or suspected overdose. Opioids can cause sleep-related breathing disorders including central sleep apnea (CSA) and sleep-related hypoxemia. Opioid use increases the risk of CSA in a dose-dependent fashion. In patients who present with CSA, consider decreasing the opioid dosage using best practices for opioid taper <span class="opacity-50 text-xs">[see Dosage and Administration ( 2.4 )]</span> .
Patient
Access to Naloxone for the Emergency Treatment of Opioid Overdose: Discuss the availability of naloxone for the emergency treatment of opioid overdose with the patient and caregiver and assess the potential need for access to naloxone, both when initiating and renewing treatment with hydrocodone bitartrate extended-release tablets. Inform patients and caregivers about the various ways to obtain naloxone as permitted by individual state naloxone dispensing and prescribing requirements or guidelines (e.g., by prescription, directly from a pharmacist, or as part of a community-based program). Educate patients and caregivers on how to recognize respiratory depression and emphasize the importance of calling 911 or getting emergency medical help, even if naloxone is administered. Consider prescribing naloxone, based on the patient’s risk factors for overdose, such as concomitant use of CNS depressants, a history of opioid use disorder, or prior opioid overdose. The presence of risk factors for overdose should not prevent the proper management of pain in any given patient. Also consider prescribing naloxone if the patient has household members (including children) or other close contacts at risk for accidental ingestion or overdose. If naloxone is prescribed, educate patients and caregivers on how to treat with naloxone [see Dosage and Administration ( 2.2 ), Warnings and Precautions ( 5.1 , 5.3 ), Overdosage ( 10 )].
