What a Pymander AI doctor consult looks like Common questions Sources Related questionsZavegepant is a CGRP receptor antagonist - it blocks a natural substance in the body that causes migraine attacks.
You may know it as Zavzpret. The nasal-spray gepant: acute migraine treatment for people whose attacks come with nausea, or whose pills stay down poorly. It does not prevent attacks.
What does it treat?
Migraine attacks - taken at the first sign.
How do you use it?
One spray into one nostril at the first sign of a migraine - one dose maximum in 24 hours. Your doctor also sets the maximum attacks to treat in 30 days. Read the spray instructions before the first dose - an attack is a bad time to learn a device. Headaches not improving, or coming more often, mean a call - not more sprays. Missed dose: not a concept here - attack-triggered only.
Side effects to know
Common: change in taste or loss of taste, nasal discomfort, nausea, and vomiting.
Serious - call your doctor immediately or get emergency care: the allergic set - rash, hives, itching, difficulty breathing, swelling of the face, throat, or around the mouth or eyes - and fingers or toes feeling numb, cool, or painful or changing color: pale, to blue, to red.
Who should not use it?
Flag severe liver or kidney disease, circulation problems in hands and feet, and every medication you take. Not a preventive: frequent attacks are the daily-preventive conversation. If you become pregnant, call your doctor.
When is it an emergency?
In an emergency, call 911Trouble breathing, face or throat swelling, or blue painful fingers or toes is a 911 call. For an overdose, call Poison Control at 1-800-222-1222. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.

Common questions
Why a nasal spray instead of a pill?
Two wins: migraine attacks often arrive with nausea - a spray does not ask a churning stomach to absorb a tablet - and nasal dosing reaches the bloodstream fast without the gut. For people whose migraines wreck digestion, or who vomit pills back up, the spray is not a preference, it is the difference between treated and untreated.
Why only one spray per 24 hours?
That is the studied and labeled maximum: one dose, one nostril, one day. The 30-day treatment cap sits on top of it - your doctor sets how many attacks per month the spray should treat. Both caps guard against medication-overuse headache, the loop where frequent rescue use starts generating headaches itself. The diary keeps you inside them.
What is with the taste change?
Listed and common: altered taste or lost taste for a while after spraying, with nasal discomfort, nausea, or vomiting as the other locals. The anatomy is simple - the nose drains to the throat, and the spray tastes like itself on the way down. It passes within hours. Persistent or severe nasal symptoms earn a mention at the next visit.
What is the finger-and-toe warning?
Named on the label for the gepant class: fingers or toes turning numb, cold, painful, or changing color - pale to blue to red - is a circulation warning and a call-your-doctor-immediately item, days after a dose counts too. Rare, specific, and worth the ten seconds it takes to remember it.
Can I use it with my other migraine medications?
Your doctor orchestrates the kit - the spray pairs with a daily preventive by design, and the acute options are assigned so they do not stack unsafely. What never flies: exceeding the caps because an attack is stubborn. New headache types - sudden thunderclap, worst-ever, with fever or weakness - get urgent care, not another spray.
What happens if the spray does nothing?
First: confirm technique - the device instructions matter, and a blocked or poorly aimed spray underdelivers. Then: one failure is a data point, a pattern is a medication conversation - other acute options exist. Headaches changing character or multiplying go to your doctor directly, not to more sprays.
