Take ergotamine as soon as migraine symptoms start.

Place a tablet under your tongue and let it dissolve. Take 1 tablet every 30 minutes as needed. Do not use more than 3 tablets in 24 hours. Do not use more than 5 tablets in 7 days.

Overuse of migraine medicine can make headaches worse. Call your doctor if your recommended dose doesn't work, or if your headaches get worse.
