If the migraine returns after being relieved, they can use another dose two hours after the last dose. The dosage should not exceed 200 mg in any twenty-four-hour period. In case you are taking the tablets after using an injection, a single dose up to 100 mg a day can be used after two hours of the first doses. It should not be used more than 200 mg in a 24 hour period. In children no average dosage information is provided. Only the doctor can say about the appropriate dose for them.
• If the patient can also take nasal spray as an alternative option for Imitrex tablets, to treat migraine headaches. He can take 5 milligrams (mg) (1 spray into one nostril) or 10 mg (2 sprays in one nostril or 1 spray in each nostril) or 20 mg (1 spray into one nostril) if he is adult. If headache doesn’t remove, he should not take another spray (5 mg, 10 mg, or 20 mg) for the same migraine attack right away. He can take it for a migraine that occurs at a later time.

The maximum dosage of injection is two 6-mg injections in a twenty-four-hour period (one day). On the other hand, some people may be directed to use no more than two 6-mg doses in a forty-eight-hour period (two days). Children should consult the doctor for appropriate dose.
