Key takeaways:
Reyvow (lasmiditan) is a prescription-only medication approved to treat migraine attacks. The typical Reyvow dosage is 50 mg to 200 mg taken once at the start of a migraine.
You should take just 1 dose of Reyvow per migraine attack, and no more than 1 dose in 24 hours. You should take no more than 4 Reyvow doses per month.
Taking more Reyvow than what’s recommended can lead to increased dizziness, drowsiness, and pins and needles sensations. So talk to your prescriber if Reyvow isn’t working for you. They may recommend adding a preventative migraine medication or trying another medication for migraine attacks.
Living with migraines can be challenging. These often-unpredictable, sometimes-severe headaches can be debilitating. In addition to causing headaches, migraines can cause nausea, vision changes, and sensitivity to lights and sounds.
One way to manage migraines is by taking medication right when you experience migraine symptoms. If over-the-counter pain relievers don’t work well enough, prescription medications may be an option. Reyvow (lasmiditan) is a prescription-only medication that’s FDA approved to treat migraines in adults.
Here, we’ll take a look at common Reyvow dosages for adults, as well as some tips for how to administer Reyvow.
Reyvow is available in 50 mg and 100 mg oral tablets. The typical Reyvow dosage is 50 mg, 100 mg, or 200 mg taken as a single dose when symptoms of a migraine attack begin. In most cases, prescribers recommend 50 mg or 100 mg per dose to start. They may recommend increasing to 200 mg if these lower doses don’t provide enough relief.
Reyvow is only taken to treat migraines once symptoms start. It’s not a medication you take every day to prevent migraines.
You shouldn’t take more than 1 dose of Reyvow for a single migraine attack. Studies found that taking a second dose of Reyvow for the same migraine attack doesn’t provide additional relief. In fact, only 1 dose of Reyvow should be taken within a 24-hour time frame.
The maximum Reyvow dosage is 200 mg per migraine attack.
You shouldn’t take more than 4 doses of Reyvow per month. This means that you shouldn’t use Reyvow to treat more than four migraine attacks per month.
And as mentioned, you should only take 1 dose of Reyvow within a 24-hour time frame, even if you experience more than one migraine during this time.

People with certain health conditions, and those who take certain medications, may need to have their Reyvow dosage adjusted or avoid the medication entirely.
Adults age 65 or older may be more likely to experience Reyvow side effects, such as dizziness, drowsiness, pins and needles sensations, and blood pressure changes. What’s more, increased dizziness and drowsiness can cause falls, which can result in injury and disability, especially in older adults.
For this reason, your prescriber may recommend starting Reyvow at a lower dose (50 mg) if you’re 65 or older.
Reyvow is partially broken down by the liver. So if you have liver disease, your body may have a harder time breaking down Reyvow. This may lead to increased blood levels of Reyvow and a higher risk of side effects.
Reyvow hasn’t been studied in people with severe liver disease. So we can’t say for sure what effects it could have in these cases. For this reason, your prescriber may recommend avoiding Reyvow entirely if you have severe liver problems, since they can’t predict how it will affect you.
Reyvow interacts with several other medications and substances. Some Reyvow interactions increase the risk of certain side effects, like drowsiness, dizziness, and impaired driving ability. Examples of substances that increase the risk of side effects when combined with Reyvow include alcohol, benzodiazepines, and opioids.
Additionally, combining Reyvow with medications that lower heart rate can make a slowed heart rate more likely. Examples of medications that can have this effect when combined with Reyvow include beta blockers and calcium channel blockers.
Always review your up-to-date medication list with your prescriber or pharmacist before you start a new medication. If you take a medication that interacts with Reyvow, your prescriber may lower the dosage of one or both of the medications.
If you’re prescribed Reyvow, keep these tips in mind to help you stay safe and get the most out of the medication:
Take Reyvow exactly as prescribed. Reyvow is a controlled substance. This means it’s more likely to be habit-forming and lead to misuse than medications that aren’t controlled substances. There’s also restrictions around how it can be prescribed and refilled. Taking Reyow exactly as prescribed helps minimize your risk of dependence and misuse.
Wait at least 8 hours after taking Reyvow before performing tasks that require mental alertness. Since Reyvow can cause drowsiness and dizziness, the manufacturer recommends waiting this long to do activities like operating machinery or driving. If you can’t wait this long, you shouldn’t take Reyvow. Your prescriber can recommend another migraine medication.
You can take Reyvow with or without food. You don’t necessarily need to take Reyvow with food. If you experience nausea after taking a dose, however, try taking it with food next time. The tablets should be swallowed whole, so don’t split or cut them.
Taking too much Reyvow increases your risk of side effects, including extreme drowsiness and dizziness. This is one reason why it’s important to limit your Reyvow usage to 1 dose per migraine (and 1 dose every 24 hours).
Additionally, taking Reyvow more often than recommended can cause rebound headaches. These are headaches that occur due to the overuse of migraine medications.
If you find yourself taking Reyvow more often than what’s recommended, speak to your prescriber. If you’re having frequent migraines, they may recommend a preventative migraine medication. Or they may recommend an alternative medication for migraine attacks.
If you think that you’ve taken too much Reyvow, you may need to be treated in a hospital. If your symptoms feel severe, seek emergency care by calling 911, or call Poison Control at 1-800-222-1222.
Reyvow (lasmiditan) is a prescription-only medication that treats migraine attacks. The typical starting dosage of Reyvow is 50 mg or 100 mg taken as a single dose at the start of a migraine. Your prescriber may recommend increasing to 200 mg if your symptoms aren’t relieved with lower doses. The maximum Reyvow dosage is 200 mg per migraine attack.
You shouldn’t take more than 1 dose of Reyvow per migraine attack, or more than 1 dose of Reyvow in 24 hours. And you shouldn’t take more than 4 doses in one month. If you find yourself needing to take Reyvow more often than recommended, talk to your prescriber. They may suggest trying a preventative migraine medication. Or they may recommend an alternative to Reyvow.
