Acute treatment of migraine with or without aura in adults. It is not used for migraine prevention and should be taken at the onset of a migraine attack.
Lasmiditan is a selective serotonin 5-HT1F receptor agonist that works on neurons in the trigeminal pain pathway. It reduces the release of pain-signaling chemicals and neurogenic inflammation associated with migraines.
Key safety concerns include significant dizziness and sedation; patients must not drive or operate machinery for at least 8 hours after taking it. Unlike triptans, it does not cause vasoconstriction, making it an option for patients with cardiovascular contraindications. Common side effects may include dizziness, fatigue, and tingling sensations.
