If a migraine recurs after the first dose of sumatriptan, what is the maximum daily dose?

Explanation:
Sumatriptan is given to treat acute migraine with a limit on how much you can take in one day. After the first dose, a second dose can be taken after at least 2 hours if the migraine returns, but the total amount taken in 24 hours must not exceed 300 mg. Since each dose is typically 50–100 mg, this means you could have up to three doses in a day (for example, three 100 mg doses), with no single dose exceeding 100 mg. This daily limit helps balance effectiveness with the risk of cardiovascular side effects from the medication.
