How should I use sumatriptan (Imitrex)?
Use exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label. Overuse of migraine headache medicine can actually make your headaches worse.
Use sumatriptan as soon as you notice headache symptoms, or after an attack has already begun.
Your doctor may want to give your first dose of this medicine in a hospital or clinic setting to see if you have any serious side effects.
Take one sumatriptan tablet whole with a full glass of water. Do not split the tablet.
After taking a tablet: If your headache does not completely go away, or goes away and comes back, take a second tablet two (2) hours after the first. Do not take more than 200 mg of sumatriptan oral tablets in 24 hours. If your symptoms have not improved, contact your doctor before taking any more tablets.
Sumatriptan nasal spray comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions. Blow your nose to clear your nasal passages before using the nasal spray. Try not to sneeze or blow your nose just after using the spray.
After using the nasal spray: If your headache does not completely go away after using the spray, call your doctor before using a second spray of sumatriptan. If your headache goes away and then comes back, you may use a second spray if it has been at least two hours since you used the first spray. Do not use more than 40 mg of sumatriptan nasal spray in 24 hours. If your symptoms do not improve, contact your doctor before using any more sprays.
