Swallow the tablets with a drink of water. If your migraine headache returns after one dose, you can take another dose as directed. You must leave at least 2 hours between doses, and do not take more than 100 mg as a single dose. Do not take more than 200 mg total in any 24 hour period. If there is no improvement at all after the first dose, do not take a second dose without talking to your prescriber or health care professional. Do not take your medicine more often than directed.
