Nurtec Side Effects: What to Expect and How to Save

Your doctor just prescribed Nurtec ODT for your migraines, and you're staring at a list of possible side effects wondering which ones you'll actually deal with. Fair question — and one that's worth answering with real numbers instead of vague reassurances.

Rimegepant (the generic name for Nurtec ODT) is a CGRP receptor antagonist approved for both acute migraine treatment and preventive use in adults with episodic migraine. It's one of the newer migraine medications on the market, and its side effect profile is considerably milder than older options like triptans. But "milder" doesn't mean "nonexistent," and you deserve to know exactly what the clinical data shows.

Common Nurtec side effects in adults

Clinical trials give us the clearest picture of what to expect. In the pivotal studies submitted to the FDA, side effects were tracked across thousands of patients taking rimegepant 75 mg — the standard dose in every Nurtec ODT tablet.

For acute migraine treatment, the most frequently reported side effect was nausea, occurring in approximately 1.4% of patients versus 0.8% on placebo. That's a small gap, and it's worth noting — many patients who report nausea during a migraine attack would experience it regardless of the medication.

For preventive use (taking Nurtec every other day), the common side effects reported more often than placebo included:

• Nausea — roughly 2.7% of patients
• Abdominal pain or stomach discomfort — approximately 2.4%
• Indigestion (dyspepsia) — around 1.5%

These are gastrointestinal effects, which makes sense given how CGRP receptors function in the gut. For most people, the nausea is mild and tends to settle after the first few weeks of regular use.

Serious side effects and allergic reactions

Serious side effects from Nurtec are uncommon, but they do exist and you should be aware of them.

Hypersensitivity reactions are the primary serious concern. These can include difficulty breathing, rash, and swelling of the face, lips, tongue, or throat. The FDA label includes a specific warning about this. If you experience any signs of a severe allergic reaction after taking Nurtec, stop the medication and get emergency medical help immediately.

These reactions have occurred in a small number of patients, including some with delayed onset (hours after dosing). The risk is higher if you've had allergic reactions to rimegepant previously — which sounds obvious, but it means you shouldn't retry the medication after a reaction without explicit guidance from your doctor.

Nurtec side effects on blood pressure

This is one of the questions that comes up frequently, and the answer is reassuring for most people. Unlike triptans — which constrict blood vessels and carry cardiovascular warnings — Nurtec does not have the same vasoconstrictive mechanism. CGRP receptor antagonists work differently, blocking the CGRP protein rather than narrowing blood vessels.

In clinical trials, rimegepant did not show clinically significant effects on blood pressure in most patients. That said, the prescribing information does note hypertension as an adverse reaction reported during post-marketing surveillance, though the frequency isn't well established.

If you have high blood pressure or cardiovascular concerns, Nurtec is generally considered a safer migraine option than triptans. But "safer" still means "discuss it with your doctor," especially if you're on blood pressure medication.

Does Nurtec cause drowsiness?

Another common concern, especially for people who need to function during a migraine attack rather than retreat to a dark room. Triptans and many older migraine medications come with significant drowsiness warnings.

Nurtec is different. Drowsiness was not identified as a common side effect in clinical trials, and it's not listed as a frequent adverse reaction in the FDA-approved labeling. Some patients do report feeling tired after taking it, but it's difficult to separate that from the migraine itself — fatigue is one of the most common migraine symptoms.

The bottom line: Nurtec is unlikely to make you drowsy, and it doesn't carry the same sedation warnings as medications like amitriptyline or some anti-nausea drugs used for migraine.

Nurtec long-term side effects

If you're taking Nurtec every other day for migraine prevention, the question of long-term safety matters. Here's what we know so far.

The longest controlled trial data comes from a 52-week open-label extension study. In that study, patients taking rimegepant every other day for up to a year showed a safety profile consistent with shorter trials — meaning no new or unexpected side effects emerged with extended use.

Liver enzyme elevations have been flagged as something to watch. In clinical trials, a small number of patients showed increases in liver enzymes (ALT and AST), though clinically significant liver injury was rare. The FDA labeling notes that patients with severe hepatic impairment should avoid Nurtec, and those with mild to moderate liver issues should be monitored.

There's no evidence of medication-overuse headache (rebound headache) with rimegepant at the recommended preventive dosing schedule. This is a meaningful advantage over some acute migraine treatments, where frequent use can paradoxically increase headache frequency.

Nurtec and weight: does it cause weight gain or weight loss?

Weight changes are not listed as a common side effect in Nurtec's clinical trial data. Unlike some preventive migraine medications — topiramate is known for weight loss, while valproate and amitriptyline often cause weight gain — rimegepant appears to be weight-neutral for most patients.

If you're experiencing weight changes while taking Nurtec, it's worth looking at other factors first: dietary changes, other medications, stress, or changes in physical activity related to migraine frequency.

Drug interactions to be aware of

Nurtec is metabolized primarily by the CYP3A4 enzyme in the liver. This matters because several common medications affect CYP3A4 activity:

Strong CYP3A4 inhibitors (like ketoconazole, itraconazole, and clarithromycin) can increase rimegepant levels in your body. If you're on one of these, your doctor may need to adjust your Nurtec dosing or monitor you more closely.

Moderate CYP3A4 inhibitors (like fluconazole, erythromycin, and grapefruit juice in large amounts) also require caution. The prescribing information recommends avoiding a second dose of Nurtec within 48 hours when used with moderate CYP3A4 inhibitors.

Strong CYP3A4 inducers (like rifampin, phenobarbital, and St. John's Wort) can decrease rimegepant levels, potentially making it less effective. Concurrent use should generally be avoided.

How Nurtec compares to other migraine medications on side effects

Understanding Nurtec's side effects in context helps. Here's how it stacks up against common alternatives:

Medication	Common Side Effects	Cardiovascular Risk	Drowsiness
Nurtec ODT (rimegepant)	Nausea (1.4–2.7%), stomach pain, indigestion	Low — no vasoconstrictive effects	Unlikely
Sumatriptan (Imitrex)	Tingling, chest tightness, drowsiness, dizziness	Higher — contraindicated in cardiovascular disease	Common
Ubrelvy (ubrogepant)	Nausea (2–5%), drowsiness (2–3%)	Low	Possible
Topiramate (Topamax)	Tingling, cognitive dulling, weight loss, taste changes	Low	Possible
Aimovig (erenumab)	Injection site reactions, constipation	Low	Unlikely

Nurtec stands out for its relatively clean side effect profile and the fact that it can serve double duty — treating acute attacks and preventing future ones with the same medication.

What Nurtec ODT costs without insurance

Here's where things get uncomfortable. Nurtec ODT is a brand-name medication with no generic equivalent currently available in the US. The wholesale acquisition cost puts a 30-day supply (for preventive use) in the range of $900 to $1,100 depending on the pharmacy.

For acute treatment only — say eight tablets per month — you're still looking at roughly $75 to $100 per tablet at most US retail pharmacies without insurance.

The rimegepant patent situation is evolving. Biohaven (now part of Pfizer) holds patents that extend protection for several more years, but the regulatory landscape for CGRP antagonists is competitive. When a generic becomes available, prices will drop substantially — but that's not helpful if you need the medication now.

How to manage Nurtec side effects

If you're experiencing side effects, a few practical steps can help:

For nausea: Try taking Nurtec with a small amount of food. While it's an orally disintegrating tablet designed to be taken without water, having something in your stomach can reduce GI irritation. Ginger tea or ginger chews before dosing is a low-risk strategy some patients find helpful.

For stomach discomfort: If indigestion or abdominal pain persists beyond the first two weeks of preventive use, talk to your doctor. The discomfort often resolves as your body adjusts, but persistent GI issues may warrant switching to an alternative.

For any allergic symptoms: Don't push through it. Rash, swelling, or breathing difficulty means stop the medication and call your doctor or go to the ER. These reactions can escalate.

General advice: Keep a simple log of when you take Nurtec and any side effects you notice. Patterns matter — and your doctor can make better adjustments with concrete data rather than vague recollections at your next appointment.

The bottom line

Nurtec ODT has one of the milder side effect profiles among migraine medications. Nausea and stomach discomfort are the most common issues, affecting a small percentage of users, and serious reactions are rare. For people who can't tolerate triptans or have cardiovascular concerns, it's a meaningful alternative.

The bigger challenge for most patients isn't the side effects — it's the cost. Without insurance, Nurtec is expensive, and that reality shouldn't be an afterthought. Cash-pay pricing through networks like CanAmerica Plus can make a real difference for uninsured and underinsured patients who need this medication.

Talk to your doctor about whether Nurtec is right for your migraine pattern, and don't settle for sticker-shock pricing without exploring your options.

Frequently asked questions

Is Nurtec safe to take every other day for prevention?

Yes — the FDA specifically approved Nurtec ODT for preventive use at a dose of 75 mg every other day. Clinical trial data covering up to 52 weeks of use at this schedule showed a consistent safety profile with no new concerning side effects emerging over time. Your doctor may still want to monitor liver function periodically, especially if you have pre-existing liver conditions.

Can I take Nurtec with other migraine medications?

Nurtec can generally be used alongside most preventive migraine medications (like beta-blockers, antidepressants, or anti-seizure drugs). However, you should avoid taking it with other CGRP-targeting medications (like Aimovig or Ajovy) without your doctor's guidance, as the combined effect on the CGRP pathway isn't well studied. Also watch for CYP3A4 drug interactions — check with your pharmacist if you're on multiple medications.

How quickly do Nurtec side effects appear?

Most side effects — particularly nausea and stomach discomfort — appear within the first few hours of taking a dose. Allergic reactions can also be delayed, occurring hours after dosing. If you're starting Nurtec for the first time, take your initial dose when you're somewhere you can monitor how you feel, rather than right before an important meeting or long drive.

Does Nurtec cause rebound headaches?

Based on current clinical evidence, rimegepant does not appear to cause medication-overuse headache (rebound headache) at the recommended dosing schedule. This is a notable advantage over triptans and combination analgesics, which can worsen headache frequency when used more than 10–15 days per month. That said, if your migraine frequency increases while on Nurtec, discuss it with your doctor.

Will my insurance cover Nurtec?

Coverage varies widely. Some commercial insurance plans cover Nurtec with prior authorization, often requiring documentation that you've tried and failed other migraine treatments first (step therapy). Medicare Part D plans may also cover it, though the out-of-pocket cost can still be significant depending on your plan's formulary tier. For patients without coverage or facing high copays, cash-pay pricing through services like CanAmerica Plus is worth comparing — it's sometimes cheaper than the insurance copay itself.
