UBROGEPANT Drug Interactions: What You Need to Know

INTERACTIONS Strong CYP3A4 Inducers: Should be avoided as concomitant use will result in reduction of ubrogepant exposure. ( 2.2 , 7.2 ) For additional dose modifications for moderate or weak CYP3A4 inhibitors and inducers or BCRP and/or P-gp only inhibitors, refer to section 2.2 . ( 7.1 , 7.2 , 7.3 )

7.1 CYP3A4 I nhibitors Co-administration of UBRELVY with ketoconazole, a strong CYP3A4 inhibitor, resulted in a significant increase in exposure of ubrogepant <span class="opacity-50 text-xs">[see Clinical Pharmacology ( 12.3 ) ]</span> . UBRELVY should not be used with strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin) <span class="opacity-50 text-xs">[see Contraindication s ( 4 )]</span> . Co-administration of UBRELVY with verapamil, a moderate CYP3A4 inhibitor, resulted in an increase in ubrogepant exposure <span class="opacity-50 text-xs">[see Clinical Pharmacology ( 12.3 ) ]</span> . Dose adjustment is recommended with concomitant use of UBRELVY and moderate CYP3A4 inhibitors (e.g., cyclosporine, ciprofloxacin, fluconazole, fluvoxamine, grapefruit juice) <span class="opacity-50 text-xs">[see Dosage and Administration ( 2.2 )]</span> . No dedicated drug interaction study was conducted with ubrogepant and weak CYP3A4 inhibitors. Dose adjustment is recommended with concomitant use of UBRELVY with weak CYP3A4 inhibitors <span class="opacity-50 text-xs">[see Dosage and Administration ( 2.2 )]</span> .

7.2 CYP3A4 I nducers Co-administration of UBRELVY with rifampin, a strong CYP3A4 inducer, resulted in a significant reduction in ubrogepant exposure [ s ee Clinical Pharmacology ( 12.3 ) ] . In patients taking strong CYP3A4 inducers (e.g., phenytoin, barbiturates, rifampin, St. John’s Wort), loss of ubrogepant efficacy is expected, and concomitant use should be avoided. Co-administration of UBRELVY with moderate or weak CYP3A4 inducers was not evaluated in a clinical study. Dose adjustment is recommended with concomitant use of UBRELVY and moderate or weak CYP3A4 inducers <span class="opacity-50 text-xs">[see Dosage and Administration ( 2.2 )]</span> . 7 .3 BCRP and / or P-gp Only Inhibitors Ubrogepant is a substrate of BCRP and P-gp efflux transporters. Use of BCRP and/or P-gp only inhibitors (e.g., quinidine, carvedilol, eltrombopag, curcumin) may increase the exposure of ubrogepant [ s ee Clinical Pharmacology ( 12.3 ) ] . Clinical drug interaction studies with inhibitors of these transporters were not conducted. Dose adjustment is recommended with BCRP and/or P-gp only inhibitors <span class="opacity-50 text-xs">[see Dosage and Administration ( 2.2 ) ]</span> .

UBRELVY is contraindicated: With concomitant use of strong CYP3A4 inhibitors [see Drug Interactions ( 7.1 )] In patients with a history of serious hypersensitivity to ubrogepant or any component of UBRELVY. Reactions have included anaphylaxis, dyspnea, and facial or throat edema [see Warnings and Precautions ( 5.1 )] Concomitant use with strong CYP3A4 inhibitors. ( 4 ) History of serious hypersensitivity to ubrogepant or any component of UBRELVY. ( 4 )

AND PRECAUTIONS Hypersensitivity Reactions: If a serious hypersensitivity reaction occurs, discontinue UBRELVY and initiate appropriate therapy. Severe hypersensitivity reactions have included anaphylaxis and dyspnea. These reactions can occur within minutes, hours, or days after administration. ( 5.1 ) Hypertension: New-onset or worsening of pre-existing hypertension may occur. ( 5.2 ) Raynaud’s phenomenon: New-onset or worsening of pre-existing Raynaud’s phenomenon may occur. ( 5.3 ) 5 .1 Hypersensitivity Reactions Hypersensitivity reactions, including anaphylaxis, dyspnea, facial or throat edema, rash, urticaria, and pruritus, have been reported with use of UBRELVY. Hypersensitivity reactions can occur minutes, hours, or days after administration. Most reactions occurred within hours after dosing and were not serious, and some reactions led to discontinuation. If a serious or severe hypersensitivity reaction occurs, discontinue UBRELVY and institute appropriate therapy [see Contraindications ( 4 ) and Adverse Reactions ( 6.2 )] . 5. 2 Hyper tension Development of hypertension and worsening of pre-existing hypertension have been reported following the use of CGRP antagonists, including UBRELVY, in the postmarketing setting. Some of the patients who developed new-onset hypertension had risk factors for hypertension. There were cases requiring initiation of pharmacological treatment for hypertension and, in some cases, hospitalization. Hypertension may occur at any time during treatment, but was most frequently reported within 7 days of therapy initiation. The CGRP antagonist was discontinued in many of the reported cases. Monitor patients treated with UBRELVY for new-onset hypertension, or worsening of pre-existing hypertension, and consider whether discontinuation of UBRELVY is warranted if evaluation fails to establish an alternative etiology or blood pressure is inadequately controlled. 5. 3 Raynaud’s Phenomenon Development of Raynaud’s phenomenon and recurrence or worsening of pre-existing Raynaud’s phenomenon have been reported in the postmarketing setting following the use of CGRP antagonists, including UBRELVY. In reported cases with small molecule CGRP antagonists, symptom onset occurred a median of 1.5 days following dosing. Many of the cases reported serious outcomes, including hospitalizations and disability, generally related to debilitating pain. In most reported cases, discontinuation of the CGRP antagonist resulted in resolution of symptoms. UBRELVY should be discontinued if signs or symptoms of Raynaud’s phenomenon develop, and patients should be evaluated by a healthcare provider if symptoms do not resolve. Patients with a history of Raynaud’s phenomenon should be monitored for, and informed about the possibility of, worsening or recurrence of signs and symptoms.
