Pentamidine may cause hypoglycemia, which may sometimes be followed by hyperglycemia. Intervention: Dosage adjustment and increased frequency of glucose monitoring may be required when LEVEMIR is co-administered with these drugs.

Drugs That May Blunt

Signs and Symptoms of Hypoglycemia Drugs: Beta-blockers, clonidine, guanethidine, and reserpine Intervention: Increased frequency of glucose monitoring may be required when LEVEMIR is co-administered with these drugs.

• Drugs that Affect Glucose Metabolism: Adjustment of insulin dosage may be needed. ( 7 )
• Antiadrenergic Drugs (e.g., beta-blockers, clonidine, guanethidine, and reserpine): Signs and symptoms of hypoglycemia may be reduced or absent. ( 5.3 , 7 )

LEVEMIR is contraindicated:

• During episodes of hypoglycemia [see Warnings and Precautions (5.3)]
• In patients with hypersensitivity to insulin detemir or any of the excipients in LEVEMIR. Reactions have included anaphylaxis [ see Warnings and Precautions (5.5) and Adverse Reactions (6.1) ] .
• During episodes of hypoglycemia ( 4 )
• Hypersensitivity to insulin detemir or any of the excipients in LEVEMIR ( 4 )

AND PRECAUTIONS

• Never Share a LEVEMIR FlexPen, insulin syringe, or needle between patients, even if the needle is changed ( 5.1 ).
• Hyperglycemia or hypoglycemia with changes in insulin regimen: Make changes to a patient’s insulin regimen (e.g., insulin strength, manufacturer, type, injection site or method of administration) under close medical supervision with increased frequency of blood glucose monitoring ( 5.2 ).
• Hypoglycemia: May be life-threatening. Increase frequency of glucose monitoring with changes to: insulin dosage, concomitant drugs, meal pattern, physical activity; and in patients with renal impairment or hepatic impairment or hypoglycemia unawareness ( 5.3 ).
• Hypoglycemia due to medication errors: Accidental mix-ups between insulin products can occur. Instruct patients to check insulin labels before injection ( 5.4 ).
• Hypersensitivity reactions: Severe, life-threatening, generalized allergy, including anaphylaxis, can occur. Discontinue LEVEMIR, monitor and treat if indicated ( 5.5 ).
• Hypokalemia: May be life-threatening. Monitor potassium levels in patients at risk for hypokalemia and treat if indicated ( 5.6 ).
• Fluid retention and heart failure with concomitant use of thiazolidinediones (TZDs): Observe for signs and symptoms of heart failure; consider dosage reduction or discontinuation if heart failure occurs ( 5.7 ).

5.1 Never Share a LEVEMIR FlexPen, Needle, or Insulin Syringe between Patients LEVEMIR FlexPen prefilled pens must never be shared between patients, even if the needle is changed. Patients using LEVEMIR vials should never share needles or syringes with another person. Sharing poses a risk for transmission of blood-borne pathogens.

5.2 Hyperglycemia or Hypoglycemia with Changes in Insulin Regimen Changes in an insulin regimen (e.g., insulin strength, manufacturer, type, injection site or method of administration) may affect glycemic control and predispose to hypoglycemia <span class="opacity-50 text-xs">[see Warnings and Precautions ( 5.4 )]</span> or hyperglycemia. Repeated insulin injections into areas of lipodystrophy or localized cutaneous amyloidosis have been reported to result in hyperglycemia; and a sudden change in the injection site (to an unaffected area) has been reported to result in hypoglycemia <span class="opacity-50 text-xs">[see Adverse Reactions ( 6 )]</span>. Make any changes to a patient’s insulin regimen under close medical supervision with increased frequency of blood glucose monitoring. Advise patients who have repeatedly injected into areas of lipodystrophy or localized cutaneous amyloidosis to change the injection site to unaffected areas and closely monitor for hypoglycemia. For patients with type 2 diabetes, dosage adjustments of concomitant antidiabetic products may be needed <span class="opacity-50 text-xs">[see Dosage and Administration ( 2.4 )]</span>.

5.3 Hypoglycemia Hypoglycemia is the most common adverse reaction of insulin, including LEVEMIR <span class="opacity-50 text-xs">[see Adverse Reactions ( 6.1 )]</span>. Severe hypoglycemia can cause seizures, may be life-threatening or cause death. Hypoglycemia can impair concentration ability and reaction time; this may place the patient and others at risk in situations where these abilities are important (e.g., driving or operating other machinery). LEVEMIR, or any insulin, should not be used during episodes of hypoglycemia <span class="opacity-50 text-xs">[see Contraindications ( 4 )]</span>. Hypoglycemia can happen suddenly and symptoms may differ in each patient and change over time in the same patient. Symptomatic awareness of hypoglycemia may be less pronounced in patients with longstanding diabetes, in patients with diabetic neuropathy, using drugs that block the sympathetic nervous system (e.g., beta-blockers) <span class="opacity-50 text-xs">[see Drug Interactions ( 7 )]</span>, or who experience recurrent hypoglycemia.

Risk

Factors for Hypoglycemia The risk of hypoglycemia generally increases with intensity of glycemic control. The risk of hypoglycemia after an injection is related to the duration of action of the insulin [see Clinical Pharmacology ( 12.2 )] and, in general, is highest when the glucose lowering effect of the insulin is maximal. As with all insulins, the glucose lowering effect time course of LEVEMIR may vary among different patients or at different times in the same patient and depends on many conditions, including the area of injection as well as the injection site blood supply and temperature. Other factors which may increase the risk of hypoglycemia include changes in meal pattern (e.g., macronutrient content or timing of meals), changes in level of physical activity, or changes to concomitant drugs [see Drug Interactions ( 7 )]. When a GLP-1 receptor agonist is used in combination with LEVEMIR, the LEVEMIR dose may need to be lowered or more conservatively titrated to minimize the risk of hypoglycemia [see Adverse Reactions ( 6.1 )] . Patients with renal or hepatic impairment may be at higher risk of hypoglycemia [see Use in Specific Populations ( 8.6 , 8.7 )].

Risk Mitigation

Strategies for Hypoglycemia Patients and caregivers must be educated to recognize and manage hypoglycemia. Self-monitoring of blood glucose plays an essential role in the prevention and management of hypoglycemia. In patients at higher risk for hypoglycemia and patients who have reduced symptomatic awareness of hypoglycemia, increased frequency of blood glucose monitoring is recommended.

5.4 Hypoglycemia Due to Medication Errors Accidental mix-ups between insulin products have been reported. To avoid medication errors between LEVEMIR and other insulins, instruct patients to always check the insulin label before each injection.

5.5 Hypersensitivity Reactions Severe, life-threatening, generalized allergy, including anaphylaxis, can occur with insulins, including LEVEMIR <span class="opacity-50 text-xs">[see Adverse Reactions ( 6.1 )]</span> . If hypersensitivity reactions occur, discontinue LEVEMIR; treat per standard of care and monitor until symptoms and signs resolve. LEVEMIR is contraindicated in patients who have had hypersensitivity reactions to insulin detemir or any of the excipients .

5.6 Hypokalemia All insulins, including LEVEMIR, cause a shift in potassium from the extracellular to intracellular space, possibly leading to hypokalemia. Untreated hypokalemia may cause respiratory paralysis, ventricular arrhythmia, and death. Monitor potassium levels in patients at risk for hypokalemia if indicated (e.g., patients using potassium-lowering medications, patients taking medications sensitive to serum potassium concentrations).

5.7 Fluid Retention and Heart Failure with Concomitant Use of PPAR-gamma Agonists Thiazolidinediones (TZDs), which are peroxisome proliferator-activated receptor (PPAR)-gamma agonists, can cause dose-related fluid retention, when used in combination with insulin. Fluid retention may lead to or exacerbate heart failure. Patients treated with insulin, including LEVEMIR, and a PPAR-gamma agonist should be observed for signs and symptoms of heart failure. If heart failure develops, it should be managed according to current standards of care, and discontinuation or dose reduction of the PPAR-gamma agonist must be considered.
