Generic name: zolmitriptan (oral) (ZOLE mi TRIP tan)

Dosage forms: oral tablet (2.5 mg; 5 mg); oral tablet, disintegrating (2.5 mg; 5 mg)

Zolmitriptan is a headache medicine that narrows blood vessels around the brain. Zolmitriptan also reduces substances in the body that can trigger headache pain, nausea, sensitivity to light and sound, and other migraine symptoms.

Zolmitriptan is used to treat migraine headaches in adults.

Zolmitriptan will only treat a headache that has already begun. It will not prevent headaches or reduce the number of attacks.

Zolmitriptan should not be used to treat a common tension headache, a headache that causes loss of movement on one side of your body, or any headache that seems to be different from your usual migraine headaches. Use this medication only if your condition has been confirmed by a doctor as migraine headaches.

Zolmitriptan may also be used for purposes not listed in this medication guide.

How should I take zolmitriptan?

Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use zolmitriptan in larger or smaller amounts or for longer than recommended.

Use zolmitriptan as soon as you notice migraine symptoms.

Take the regular tablet whole with a full glass of water.

To take the orally disintegrating tablet (Zomig-ZMT):

  • Keep the tablet in its blister pack until you are ready to take it. Open the package and peel back the foil. Do not push a tablet through the foil or you may damage the tablet.
  • Use dry hands to remove the tablet and place it in your mouth.
  • Do not swallow the tablet whole. Allow it to dissolve in your mouth without chewing. If desired, you may drink liquid to help swallow the dissolved tablet.

After taking a tablet: If your headache does not completely go away, or goes away and comes back, take a second tablet 2 hours after the first. Do not take more than 10 mg of zolmitriptan in 24 hours. If your symptoms have not improved, contact your doctor before taking any more tablets.

Call your doctor if your headache does not go away at all after taking the first zolmitriptan tablet.

Never use more than your recommended dose. Overuse of migraine headache medicine can make headaches worse.

Contact your doctor if you have more than four headaches in one month (30 days). Tell your doctor if this medicine seems to stop working as well in treating your migraine attacks.

Zolmitriptan can raise blood pressure to dangerous levels. Your blood pressure may need to be checked often while you are using this medicine. Your heart function may need to be checked using an electrocardiograph or ECG (sometimes called an EKG).

Store at room temperature away from moisture, heat, and light.
