How It Works

CGRP (calcitonin gene-related peptide) is central to migraine:

• Levels increase during migraine attacks
• Causes inflammation and pain sensitization
• Blocking it prevents and relieves migraine

Rimegepant:

• Blocks CGRP receptors
• Reduces migraine-related inflammation
• Works for both acute attacks and prevention

Common Uses

Acute Treatment

• Treatment of migraine attacks as they occur
• Migraine with or without aura
• Alternative when triptans contraindicated or don't work

Preventive Treatment

• Reduce frequency of migraine attacks
• For patients with frequent migraines
• Alternative to daily preventive medications

How to Use

For Acute Treatment

• Dose: 75 mg at migraine onset
• Maximum: 75 mg in 24 hours. Safety of more than 18 doses in 30 days has not been established
• Technique: Place on tongue; dissolves without water

For Prevention

• Dose: 75 mg every other day
• Take consistently for prevention benefit
• Ask for a written breakthrough-migraine plan; count preventive and rescue doses together

Administration

• Remove tablet from blister with dry hands
• Place on tongue
• Tablet dissolves within seconds
• No water needed (but can take with water if preferred)
• Can take with or without food

What to Expect

Acute Use

• Relief typically begins within hours
• Addresses pain and associated symptoms
• Not a vasoconstrictor like triptans, but cardiovascular history still matters

Prevention

• Reduces monthly migraine days
• May take weeks to see full benefit
• Track migraine days and total doses to review the plan with your prescriber

Side Effects

Common

• Nausea
• Abdominal pain/indigestion

Less Common

• Hypersensitivity reactions (rare)

Generally Well-Tolerated

• Lower side effect burden than many preventives
• No triptan-like vasoconstrictive effects; current labeling warns about new or worsening hypertension and Raynaud's phenomenon
• No triptan-like sensations

Advantages of Nurtec

Dual Use

• Only medication approved for both acute and preventive treatment
• Simplifies regimen for some patients
• Flexibility in dosing

Vs. Triptans

• No blood vessel constriction
• May be an option when triptans are unsuitable, but cardiovascular disease and blood pressure history should be reviewed
• Use caution and monitor in patients with hypertension or circulation disorders
• Different mechanism if triptans fail

Orally Disintegrating Tablet

• No water needed
• Good when nausea makes swallowing difficult
• Convenient

Precautions

• Pregnancy: Limited data; discuss with doctor
• Breastfeeding: Human milk transfer appears low (<1% relative infant dose), but infant-effect data are limited; discuss timing and infant age with your clinician
• Severe hepatic impairment: Avoid use
• Drug interactions: Avoid strong CYP3A4 inhibitors and strong/moderate CYP3A inducers. Moderate CYP3A4 inhibitors or potent P-gp inhibitors require at least 48 hours before another dose; ask the pharmacist to check your complete list
• Don't exceed recommended doses

Track Whether It Helps

Record migraine days, disability, total Nurtec doses, other rescue medicines, and any side effects. Agree on a review date and what to take if an attack persists. A new or unusually severe headache, sudden vision loss, weakness, or speech difficulty needs emergency assessment rather than another migraine dose.

Cost and Insurance

• Brand-name medication
• May require prior authorization for prevention
• Often approved more easily for acute use
• Manufacturer savings programs available

Frequently Asked Questions

Can Nurtec be used for both treatment and prevention at the same time?

It has both indications, but your prescriber should define whether and how to use an off-day rescue dose. Never exceed 75 mg in 24 hours, interactions may require longer spacing, and safety above 18 total doses in 30 days is unestablished.

How long until I see preventive benefit?

Preventive effects may take several weeks to become apparent. Continue taking as prescribed and track your migraine frequency.

Is Nurtec better than triptans?

They're different. Triptans are effective and well-established. Nurtec offers an alternative mechanism without triptan-style vasoconstrictive restrictions. Some patients respond better to one than the other.

Can I take Nurtec if I have heart problems?

Unlike triptans, Nurtec does not have triptan-style vasoconstrictive contraindications. However, current labeling warns about new or worsening hypertension and Raynaud's phenomenon, so always discuss your complete medical history with your doctor.

What if Nurtec doesn't work for my acute migraine?

You can only take one dose per 24 hours. If Nurtec isn't effective, discuss alternatives with your doctor. Not every medication works for every patient.

Does the ODT really work without water?

Yes, the orally disintegrating tablet dissolves quickly on your tongue. You can take it with water if you prefer, but it's not necessary.
