Rimegepant (Nurtec®) is a dissolvable oral medication used to treat acute migraine attacks when they happen. It belongs to a class of treatments called gepants, which are small molecule oral CGRP antagonists.
Rimegepant (Nurtec®) is unique in that outside of Canada it has been approved for both the acute and preventive treatment of migraine.

Rimegepant (Nurtec®) is used for the acute treatment migraine attacks.
It is taken daily as needed after a migraine attack starts.
In other countries (e.g., the United States), rimegepant (Nurtec®) is also approved for the prevention of migraine.
At the Ottawa Headache Centre, we consider rimegepant (Nurtec®) when:
there is a high frequency of migraine attacks risking medication-overuse headache
the side-effects of triptans are poorly tolerated
triptans have not been effective in stopping migraine attacks
there are contraindications to using triptans (e.g., high risk of stroke or heart attack)
there is concurrent medication-overuse headache
multiple different acute treatments are needed
patients need better control of menstrual-related migraine
it fits as an off-label preventive strategy
Currently, rimegepant (Nurtec®) does not have coverage under the Exceptional Access Program.
Individual drug plans vary regarding their coverage of gepants for migraine.
If you are having poorly controlled migraine attacks, then ask for a referral to the Ottawa Headache Centre. We can explore whether gepants can play a role in the acute treatment of your attacks.
Rimegepant (Nurtec®) blocks the action of CGRP, a chemical involved in migraine pain signaling.
By reducing CGRP activity, it:
Lowers the likelihood that a migraine attack will persist.
Decreases the severity of migraine attacks.
Lowers the pain associated with migraine attacks.
As a gepant, the benefits of rimegepant (Nurtec®) include that it:
does not cause medication overuse headache
does not constrict blood vessels
is generally very tolerable for most people
is safe for many people who cannot take triptans
Rimegepant (Nurtec®) can be a useful medication to stop migraine attacks and prevent migraine attacks from occurring.
If you are considering Nurtec® (or have been referred), our consultation helps:
confirm whether rimegepant (Nurtec®) fits your migraine profile
understand the benefits and short-comings of gepants, especially when compared to other acute medications (i.e., triptans)
and place it into a broader, individualized care plan (including acute and non-medication strategies).
Ask your doctor for a referral to the Ottawa Headache Centre if you want to learn more about your migraine-specific preventive options.
Rimegepant (Nurtec®) is generally well tolerated.
Possible side effects include:
Constipation
Nausea
Fatigue
Drowsiness
Serious side effects are uncommon.
Not currently.
Rimegepant (Nurtec®) is not recommended during pregnancy due to limited safety data.
If pregnancy is planned:
Rimegepant (Nurtec®) should be stopped at least 1 week before pregnancy
This allows time for the medication to fully clear from the body.
If you are pregnant or planning pregnancy, we will help you find alternative migraine strategies.
Data on gepant use and breastfeeding are limited but growing. Small case series suggest the amount of gepants - including rimegepant (Nurtec®) in breastmilk is small.
We help guide the discussion around gepant-use during breastfeeding and lactation to help you make an informed decision.
From a medical perspective, rimegepant (Nurtec®) can be used:
Alone
Alongside triptans
Alongside other oral preventive medications
Alongside other CGRP preventive antagonists
Concurrently with Botox® for chronic migraine
Data are lacking regarding safety and efficacy of combining rimegepant (Nurtec®) with ubrogepant (Ubrelvy®), or atogepant (Qulipta®).
