The recommended dose of IMITREX Tablets is 25 mg, 50 mg, or 100 mg. Doses of 50 mg and 100 mg may provide a greater effect than the 25-mg dose, but doses of 100 mg may not provide a greater effect than the 50-mg dose. Higher doses may have a greater risk of adverse reactions [see Clinical Studies (14)].
If the migraine has not resolved by 2 hours after taking IMITREX Tablets, or returns after a transient improvement, a second dose may be administered at least 2 hours after the first dose. The maximum daily dose is 200 mg in a 24-hour period.
Use after IMITREX Injection: If the migraine returns following an initial treatment with IMITREX (sumatriptan succinate) Injection, additional single IMITREX Tablets (up to 100 mg/day) may be given with an interval of at least 2 hours between tablet doses.
The safety of treating an average of more than 4 headaches in a 30-day period has not been established.
