REYVOW (lasmiditan) is the first and only FDA-approved ditan—a high-affinity 5-HT1F receptor agonist1
5-HT1F receptors, involved in modulating pain signaling, are present on both the peripheral and central pain pathways.2,3 Based on the location of 5-HT1F receptors, REYVOW is believed to act both centrally and peripherally.3
In preclinical studies:
REYVOW is a Selective 5-HT1F Receptor Agonist1
REYVOW is not a triptan. In preclinical studies, REYVOW was shown to have more than 440-fold greater selectivity for the 5-HT1F receptor than for the 5-HT1B and the 5-HT1D receptors.1,4
Activation of 5-HT1F receptors has been observed in preclinical studies to:2,5,6
SELECT IMPORTANT SAFETY INFORMATION
Medication Overuse Headache
Overuse of acute migraine drugs may lead to exacerbation of headache (i.e., medication overuse headache). Medication overuse headache may present as migraine-like daily headaches or as a marked increase in frequency of migraine attacks. Detoxification of patients including withdrawal of the overused drugs and treatment of withdrawal symptoms (which often includes a transient worsening of headache) may be necessary.
INDICATION AND USAGE
REYVOW is indicated for the acute treatment of migraine with or without aura in adults.
Limitations of Use: REYVOW is not indicated for the preventive treatment of migraine.
IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
REYVOW may cause significant driving impairment. In a driving study, administration of single 50 mg, 100 mg, or 200 mg doses of REYVOW significantly impaired subjects' ability to drive. Additionally, more sleepiness was reported at 8 hours following a single dose of REYVOW compared to placebo. Advise patients not to engage in potentially hazardous activities requiring complete mental alertness, such as driving a motor vehicle or operating machinery, for at least 8 hours after each dose of REYVOW. Patients who cannot follow this advice should not take REYVOW. Prescribers and patients should be aware that patients may not be able to assess their own driving competence and the degree of impairment caused by REYVOW.
Central Nervous System Depression
REYVOW may cause central nervous system (CNS) depression, including dizziness and sedation. Because of the potential for REYVOW to cause sedation, other cognitive and/or neuropsychiatric adverse reactions, and driving impairment, REYVOW should be used with caution if used in combination with alcohol or other CNS depressants. Patients should be warned against driving and other activities requiring complete mental alertness for at least 8 hours after REYVOW is taken.
In clinical trials, reactions consistent with serotonin syndrome were reported in patients treated with REYVOW who were not taking any other drugs associated with serotonin syndrome. Serotonin syndrome may also occur with REYVOW during coadministration with serotonergic drugs. Serotonin syndrome symptoms may include mental status changes, autonomic instability, neuromuscular signs, and/or gastrointestinal signs and symptoms. The onset of symptoms usually occurs within minutes to hours of receiving a new or a greater dose of a serotonergic medication. Discontinue REYVOW if serotonin syndrome is suspected.
Medication Overuse Headache
Overuse of acute migraine drugs may lead to exacerbation of headache. Medication overuse headache may present as migraine-like daily headaches or as a marked increase in frequency of migraine attacks. Detoxification of patients including withdrawal of the overused drugs and treatment of withdrawal symptoms (which often includes a transient worsening of headache) may be necessary.
The most common adverse reactions associated with REYVOW (≥2% and greater than placebo in clinical studies) were dizziness, fatigue, paresthesia, sedation, nausea and/or vomiting, and muscle weakness.
