ZAVEGEPANT Drug Interactions: What You Need to Know

INTERACTIONS

• Avoid use with drugs that inhibit OATP1B3 or NTCP transporters. ( 7.1 )
• Avoid use with drugs that induce OATP1B3 or NTCP transporters. ( 7.2 )
• Avoid use of intranasal decongestants; if unavoidable, administer intranasal decongestants at least 1 hour after ZAVZPRET administration. ( 7.3 )

7.1 OATP1B3 or NTCP Inhibitors Concomitant administration of ZAVZPRET with inhibitors of the organic anion transporting polypeptide 1B3 (OATP1B3) or sodium taurocholate co-transporting polypeptide (NTCP) transporters may result in a significant increase in zavegepant exposure. Avoid concomitant administration of ZAVZPRET with drugs that inhibit OATP1B3 or NTCP transporters <span class="opacity-50 text-xs">[see Clinical Pharmacology (12.3) ]</span> .

7.2 OATP1B3 or NTCP Inducers Concomitant administration of ZAVZPRET with inducers of OATP1B3 or NTCP transporters may result in a decrease in zavegepant exposure. Avoid concomitant administration of ZAVZPRET with drugs that induce OATP1B3 or NTCP transporters <span class="opacity-50 text-xs">[see Clinical Pharmacology (12.3) ]</span> .

7.3 Intranasal Decongestants Concomitant administration of ZAVZPRET with intranasal decongestants may decrease the absorption of zavegepant. Avoid concomitant administration of intranasal decongestants with ZAVZPRET. When concomitant use is unavoidable, intranasal decongestants should be administered at least 1 hour after ZAVZPRET administration <span class="opacity-50 text-xs">[see Clinical Pharmacology (12.3) ]</span> .

ZAVZPRET is contraindicated in patients with a history of hypersensitivity reaction to zavegepant or any of the components of ZAVZPRET. Reactions have included anaphylaxis [see Warnings and Precautions (5.1) ] . Patients with a history of hypersensitivity reaction to zavegepant or to any of the components of ZAVZPRET. ( 4 )

AND PRECAUTIONS

• Hypersensitivity Reactions: If a serious hypersensitivity reaction occurs, discontinue ZAVZPRET and initiate appropriate therapy. Hypersensitivity reactions including anaphylaxis, facial swelling, and urticaria, have occurred with ZAVZPRET. ( 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 Serious hypersensitivity reactions, including anaphylaxis, facial swelling, and urticaria, have occurred in patients treated with ZAVZPRET. If a hypersensitivity reaction occurs, discontinue ZAVZPRET and initiate appropriate therapy <span class="opacity-50 text-xs">[see Contraindications (4) and Adverse Reactions (6.1 , 6.2) ]</span>.

5.2 Hypertension Development of hypertension and worsening of pre-existing hypertension have been reported following the use of CGRP antagonists in the postmarketing setting. Some of the patients receiving a CGRP antagonist 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 ZAVZPRET for new-onset hypertension or worsening of pre-existing hypertension, and consider whether discontinuation of ZAVZPRET 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. 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. ZAVZPRET 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.
