Migraine affects millions of people worldwide, often disrupting daily life with intense, recurring headaches and associated symptoms like nausea, light sensitivity, and fatigue. While injectable treatments and daily preventives have helped many patients manage symptoms, a new option offers fast relief without the need for a shot or pill.

Zavzpret (zavegepant) is a nasal spray medication developed specifically for the acute treatment of migraine attacks. Approved by the FDA in 2023, Zavzpret is the first CGRP receptor antagonist available as a nasal spray — designed for people who need fast, convenient treatment during a migraine episode.
How Zavzpret Works
Zavzpret belongs to a class of drugs known as gepants, which target the CGRP (calcitonin gene-related peptide) pathway — a key component in the migraine process. During a migraine attack, CGRP levels rise, triggering inflammation and pain signals in the brain. By blocking CGRP receptors, Zavzpret helps stop the migraine in its tracks.
What sets Zavzpret apart is its intranasal delivery system. This allows the medication to be absorbed quickly, bypassing the gastrointestinal tract. For patients who experience nausea or vomiting with migraines — or who have difficulty swallowing pills — this can be an important advantage.
How Fast Does It Work?
In clinical trials, Zavzpret demonstrated:
Pain relief as early as 15 minutes
Significant symptom reduction at 30 minutes
Sustained relief up to 48 hours for some patients
Zavzpret is designed for acute use, meaning it is taken at the onset of a migraine, not as a preventivetreatment. It can be taken with or without food and does not require routine dosing.
Who Might Consider Zavzpret?
Zavzpret may be a good option for:
Patients who prefer non-oral treatments
Individuals who experience rapid-onset or severe migraine attacks
People who have not responded to triptans or cannot take them due to cardiovascular risks
Patients with migraine-related nausea, where swallowing tablets is difficult
Because Zavzpret does not constrict blood vessels like triptans, it may also be better tolerated in people with heart conditions, though a healthcare provider should assess each case.
Side Effects and Safety
Zavzpret is generally well-tolerated. The most commonly reported side effects include:
Taste disturbance (dysgeusia)
Nasal discomfort or irritation
Nausea
Fatigue
These effects were typically mild and temporary. As with any prescription medication, it’s important to review potential drug interactions and health conditions with a provider before starting treatment.
Access and Availability
Zavzpret is available by prescription in the United States and is manufactured by Pfizer. Some insurance plans may cover it, and patient support programs are available to help with affordability. It comes as a single-use nasal spray device, preloaded for one-time administration.
Final Thoughts
For individuals seeking a fast, needle-free option to manage migraine attacks, Zavzpret offers a clinically proven solution with a unique delivery method. Its rapid onset, convenient use, and CGRP-blocking action make it a promising addition to the evolving landscape of migraine care.
If migraines are interfering with your life, talk to your healthcare provider about whether a CGRP nasal spray treatment like Zavzpret may be right for you.
