What Are Ubrelvy and Nurtec?
Ubrelvy and Nurtec are both oral gepants, a newer class of migraine medication that blocks a protein called CGRP instead of narrowing blood vessels the way older triptans do. I see patients ask about these two medications constantly, usually because a doctor mentioned one and a friend or forum swears by the other. Ubrelvy contains ubrogepant and is approved only for treating a migraine attack once it starts. Nurtec ODT contains rimegepant and carries a dual approval, meaning it can treat an active attack and also be taken every other day to help prevent future ones. Both drugs work by stopping CGRP from binding to its receptors, which interrupts the inflammation and pain signalling that drive a migraine attack.
How Fast Does Ubrelvy Start Working?
Ubrelvy typically begins easing pain within one to two hours of taking a dose, with peak drug levels in the blood reached at around ninety minutes. It comes as a tablet you swallow whole with water, in 50 mg or 100 mg strengths. If the first dose has not fully resolved symptoms after two hours, I often tell patients they can take a second dose, up to a maximum of 200 mg in twenty-four hours. The option to take a second dose is especially helpful for stubborn migraines.
How Fast Does Nurtec ODT Start Working?
Nurtec ODT is a dissolvable tablet that some patients feel starts working within fifteen to thirty minutes, though it also reaches peak blood levels at roughly the same one-and-a-half-hour mark as Ubrelvy. Because it dissolves on or under the tongue without water, it can feel faster in practice, particularly for someone who is nauseated and struggling to swallow a standard pill. The dose is fixed at 75 mg, taken once for an acute attack, with no approved second dose on the same day.
Which Medication Has Better Clinical Trial Results?
Head-to-head trial data shows the two drugs perform similarly, with neither holding a clear efficacy advantage. According to SingleCare, pooled trial data found around 62 percent of Ubrelvy users reported pain relief at two hours compared with roughly 59 percent for Nurtec, a gap small enough that researchers do not consider it clinically meaningful. A separate large comparative analysis spanning dozens of randomized trials of gepants and other newer migraine medications found no statistically significant difference in two-hour pain freedom or pain relief between Ubrelvy, Nurtec, and Reyvow (a ditan, not a gepant). In practical terms, this means the honest answer to which works better usually comes down to individual response rather than one drug being superior on paper.
What Is the Difference in How Long Relief Lasts?
Nurtec tends to provide longer lasting relief because of its longer half-life, while Ubrelvy clears the body somewhat faster. Nurtec’s half-life runs around eleven hours compared with five to seven hours for Ubrelvy, and some patients report pain relief extending toward the forty-eight-hour mark after a single Nurtec dose. Ubrelvy’s shorter half-life is part of why a second dose is built into its dosing schedule for attacks that resurface.
Can Nurtec Be Used to Prevent Migraines Too?
Yes, Nurtec ODT is the only one of the two approved for both acute treatment and prevention of episodic migraine. Patients using it preventively typically take 75 mg every other day regardless of whether a migraine is active. Ubrelvy does not carry this dual approval and is intended strictly for treating an attack that has already started. As reported by GoodRx, this difference is often the deciding factor for people who experience frequent migraines and would rather manage one medication instead of separate treatment and prevention drugs.
What Are the Side Effects of Ubrelvy vs Nurtec?
Both drugs cause broadly similar mild side effects, most commonly nausea, sleepiness, and dry mouth. Nurtec ODT has also been associated with abdominal discomfort and indigestion in some patients, according to Healthline. Serious allergic reactions are uncommon with either drug but have been reported, so any swelling, rash, or difficulty breathing after a dose needs urgent medical attention. Neither drug causes the blood vessel narrowing associated with triptans, which is why both are generally considered safer options for people with cardiovascular risk factors, though this should always be confirmed with a prescriber first.
Can I Switch Between Ubrelvy and Nurtec, or Take Them Together?
I do not recommend combining Ubrelvy and Nurtec on the same day, since they work on the same CGRP pathway and stacking them raises the risk of side effects without adding meaningful benefit. Switching from one to the other is generally safe under medical guidance if the first option is not controlling symptoms well. Some patients are prescribed both as part of a structured plan, for example Nurtec every other day for prevention with Ubrelvy reserved for breakthrough attacks on the off days, but this kind of combination therapy should only be set up by a prescriber who knows the full picture.
Which One Should You Choose?
There is no universal winner between Ubrelvy and Nurtec, and the right choice depends on your migraine pattern and personal preference. If you need only acute treatment and like the reassurance of a second dose option, Ubrelvy may suit you better. If you get frequent migraines and want one medication that treats and prevents, or you struggle to swallow pills during an attack, Nurtec’s dissolvable format and dual approval often make more sense. I always encourage patients to bring their migraine frequency, nausea patterns, and any heart or liver conditions to this conversation with their prescriber, since that context matters more than any head-to-head statistic.
FAQS
Q1. Is Nurtec or Ubrelvy better for migraines?
Neither drug is consistently better than the other in clinical trials, since both show similar two-hour pain relief rates. The better choice depends on whether you also need migraine prevention, which only Nurtec offers, and on your personal tolerance for each drug’s side effects.
Q2. How long does it take Ubrelvy to work?
Ubrelvy typically starts easing migraine pain within one to two hours, with peak blood levels reached around ninety minutes after a dose. A second dose can be taken after two hours if the first has not fully worked.
Q3. Can Nurtec be used for both treating and preventing migraines?
Yes, Nurtec ODT is FDA approved for both acute treatment of an active migraine and prevention of episodic migraine when taken every other day. Ubrelvy is approved for acute treatment only.
Q4. Can I take Ubrelvy the day after taking Nurtec?
Taking these medications on separate, non-overlapping days is generally considered acceptable under medical guidance, but they should not be taken on the same day. Always confirm timing with your prescriber, especially if you are using one preventively and the other for breakthrough attacks.
Q5. Which one is better if my migraines come with nausea?
Nurtec ODT’s dissolvable tablet can be easier to take during a nauseated migraine attack since it does not require swallowing water. Ubrelvy is still effective for nausea related migraines but requires swallowing a standard tablet.
Q6. Has anyone tried both Ubrelvy and Nurtec, and which worked faster?
Patient experiences vary widely, and this mirrors what clinical trials show, since neither drug has a consistent speed advantage over the other. Some people feel Nurtec’s dissolvable form act faster subjectively, while others find Ubrelvy’s swallowable tablet more reliable for their attack pattern.
Call to Action
If migraines are disrupting your life, you are not alone, and understanding your options is the first step toward better control. I have written more on migraine triggers, prevention strategies, and other treatment classes over on pharmahealths.com, and I would encourage you to explore those articles alongside this one before your next appointment. Before you go, take a moment to note how often your migraines occur, how quickly they build, and whether nausea affects how you take medication, as this can help your doctor choose the right treatment faster.
