What is rimegepant?

Rimegepant is a prescription medicine used by adults to treat migraines (with or without aura) when they occur and also to prevent episodic migraines. Rimegepant works to reduce migraine symptoms of headache, nausea, vomiting, light sensitivity and sound sensitivity, by blocking CGRP receptors. This medicine may reduce the number of monthly migraine days when taken to prevent episodic migraines.

Rimegepant is an orally disintegrating tablet (ODT) that dissolves in the mouth without the need to take it with a glass of water. Because the tablet dissolves in the mouth it is absorbed into the bloodstream quickly, with the highest blood concentrations reached after one and a half hours.


It is not known if it is safe to take rimegepant ODT for more than 15 migraine headaches in 30 days.

Rimegepant ODT can be taken 1 time each day as needed. You should not take more than 1 tablet in 24 hours.

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

If you take too much rimegepant ODT, go to the nearest emergency room right away.

Before taking this medicine

You should not use rimegepant if you are allergic to it.

It is not known whether rimegepant will harm an unborn baby. However, having migraine headaches may cause complications during pregnancy such as dangerously high blood pressure that can lead to medical problems in both mother and baby. The benefit of treating migraines may outweigh any risks to the baby.

It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.

Rimegepant is not approved for use by anyone younger than 18 years old.
