Reyvow: Questions you may have

Here are some common questions about Reyvow and brief answers to them. If you’d like to know more about these topics, ask your doctor.

Will Reyvow make me feel ‘high’?

Possibly. In rare cases, Reyvow may cause euphoria as a side effect. Euphoria can be described as feeling “high” or having a sense of extreme happiness.

Euphoria was not commonly reported in clinical studies of Reyvow. However, medications that cause euphoria as a side effect often carry a risk of misuse. (With misuse, a drug is taken in a way other than how it was prescribed by a healthcare professional.)

Due to this risk, Reyvow is a controlled substance. To learn more, see “Why is Reyvow a controlled substance?” below.

Why is Reyvow a controlled substance?

Reyvow is a Schedule V controlled substance. This means the drug has approved medical uses, but it also carries a risk of misuse. (With misuse, a drug is taken in a way other than how it was prescribed by a healthcare professional.)

Controlled substances have specific regulations that doctors must follow when prescribing them. Keep in mind that drugs with a lower schedule number have a greater risk of misuse than drugs with a higher schedule number. For example, Schedule II drugs have a greater risk of misuse than Schedule III drugs.

In clinical studies, Reyvow was shown to have a risk of misuse. In addition, certain rare side effects of Reyvow may increase its risk of misuse. Examples include hallucinations and euphoria (feeling “high”).

Other factors can also increase the risk of misuse with Reyvow. For example, people who have drug dependence or alcohol use disorder may have a higher risk for misuse of the drug. If you have these conditions or had them in the past, talk with your doctor. They’ll advise whether it’s safe for you to take Reyvow.

Can I drive after taking Reyvow?

No, you should not drive soon after taking Reyvow. In fact, it’s recommended that you avoid driving for at least 8 hours after taking a dose of the drug.

This is because Reyvow can cause slowing of the central nervous system (CNS) as a side effect. Reduced activity of the CNS may lead to severe dizziness or drowsiness. These side effects could be dangerous if they occur while you’re driving. For this reason, it’s best not to drive or perform activities that require you to be alert within 8 hours after taking Reyvow.

If you’re unable to avoid driving for at least 8 hours after taking Reyvow, talk with your doctor. They can recommend treatments other than Reyvow for your condition.  

Reyvow: How it works

Reyvow is approved to treat migraine episodes that happen with or without aura in adults. To learn more about this condition, see the “Reyvow: Use for migraine” section above.

Reyvow belongs to a class of drugs called serotonin receptor agonists. (Serotonin is a chemical produced in your brain.)

The exact way Reyvow works to treat migraine isn’t known. The drug is thought to attach to serotonin receptors (binding sites) in the brain. By doing this, Reyvow may help block pain signals that cause migraine episodes. As a result, Reyvow helps ease the symptoms of a migraine episode.

How long does Reyvow take to start working?

Many people using Reyvow in clinical studies reported an easing of their migraine symptoms within 2 hours of taking a dose.

How long does Reyvow last in your body?

Reyvow likely stays in your body for about 1 day.

This is based on Reyvow’s half-life. (A drug’s half-life is the amount of time it takes for half of a drug’s dose to leave your body.) Reyvow’s half-life is about 5.7 hours. This means it takes about 5.7 hours for half of a drug’s dose to leave your body.

It usually takes about five half-lives for a drug to leave your body completely. For Reyvow, this means the drug stays in your body for about 28.5 hours. 

Reyvow: Consuming alcohol during treatment

You should not drink alcohol while taking Reyvow.

This is because both Reyvow and alcohol can cause slowing of the central nervous system (CNS), which may lead to dizziness or drowsiness. Taking Reyvow with alcohol could worsen these side effects.

In addition, drinking alcohol can trigger a migraine episode for some people. (Reyvow is used to treat migraine episodes.) If you drink alcohol and it is a known trigger for your migraine episodes, it may be best to avoid drinking it while taking this medication.

If you have questions about drinking alcohol while taking Reyvow, talk with your doctor.
