Hypersensitivity reactions, including facial swelling and urticaria, have occurred in patients treated with ZAVZPRET in clinical studies. If a hypersensitivity reaction occurs, discontinue ZAVZPRET and initiate appropriate therapy [see Contraindications (4) and Adverse Reactions (6.1)].
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.
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.
