Maxat and Maxalt-MLT will start to work for a migraine headache within 30 minutes for some patients. By 2 hours, there is a 60% to 70% chance of having a headache response (no pain or mild pain) in patients being treated with Maxalt or Maxalt-MLT.

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

  • In studies with Maxalt (rizatriptan), there was a 20% probability of achieving a migraine headache response (no pain or mild pain) with a 10 mg dose after 30 minutes compared to about 10% probability with the 5 mg dose or a placebo (an inactive pill).
  • At 2 hours after taking a dose, the probability of a headache response increased to 65% to 70% in patients using Maxalt, compared to about 40% in the placebo group.
  • In studies evaluating Maxalt-MLT, the orally-disintegrating form of Maxalt, there was a 20% probability of achieving a headache response (no pain or mild pain) with a 10 mg dose after 30 minutes compared to about 15% probability with the 5 mg dose and 10% probability with a placebo (an inactive pill).
  • At 2 hours after taking a dose, the probability of a migraine headache response increased to 60% to 70% in patients using Maxalt-MLT, compared to about 35% in the placebo group.

In all studies with Maxalt or Maxalt-MLT (5 or 10 mg), more patients achieved a significant headache response 2 hours after treatment when compared to the group taking a placebo.
