Zavzpret™ (zavegepant) is a calcitonin gene-related peptide (CGRP) blocker. It is approved by the US Food and Drug Administration (FDA) to treat acute (short-term) migraine with or without aura.As of 2023, Zavzpret is the only CGRP nasal spray. This may be helpful for people who cannot take pills, like when migraine is accompanied by nausea and vomiting.1,2
Migraine is the third most common health condition worldwide, affecting over 1 billion people. It is a major cause of disability. Migraine can occur with or without aura. Aura is a change to the senses. It may occur as:1-3
- Visual disturbances, like flashing lights, zigzag lines, or blind spots
- Sensory disturbances, like tingling or numbness
- Speech or language problems
CGRP blockers are a new kind of drug that can help with migraine. They stop CGRP, a protein that plays a role in migraine, from working. They are the first kind of migraine drug that does not make blood vessels in the head get smaller (constrict). CGRP blockers have been shown to have fewer side effects and may also last longer than other drugs used to treat migraine.4
What are the ingredients in Zavzpret?
The active ingredient in Zavzpret is zavegepant.1
How does Zavzpret work?
Zavzpret is a CGRP receptor antagonist (also called a CGRP blocker). It works by blocking the CGRP receptors. This reduces migraine pain, nausea, and sensitivity to light and sound.1
When CGRP levels are high, it can cause inflammation and pain. When Zavzpret blocks the CGRP receptors, it stops the protein from causing inflammation and pain.1,3
Zavzpret is taken as a nasal (in the nose) spray. It is not a cure for migraine. But it can help to reduce how often a person has migraine attacks and how severe the attacks are.1

The most common side effects of Zavzpret are:1
