What is this medication for?

Naratriptan is a selective serotonin receptor agonist. It works by reducing inflammation and reversing the widening of blood vessels in the brain, thereby stopping a migraine headache. It is often used to treat a migraine attack after it begins. It will not prevent a migraine.

How should I take or use this medication?

• Follow your doctor’s instructions as to how many tablets to take when the attack starts. It should work within 1-2 hours.
• If your migraine improves but comes back, wait at least 4 hours before taking the next dose. Do not take more than 2 tablets (5mg) per day.
• If you have kidney or liver impairment, do not take more than 1 tablet in 24 hours.
• Do not use naratriptan too frequently (limit of 10 days per month), as it can cause medication overuse headache (migraine/headache may worsen). Inform your doctor if you need to take naratriptan to treat more than 4 headaches in a 1 month period.
