Sumatriptan Orion is a medicine used to treat migraine attacks in adults.
The usual dose for adults is one 50 mg tablet. Some people may need a 100 mg tablet. Always follow your doctor's instructions.
Swallow the tablet whole with water. Take it as soon as you feel a migraine attack starting, but you can take it at any time during the attack.
Do not take more than 300 mg (e.g., six 50 mg tablets or three 100 mg tablets) in a 24-hour period. If symptoms return, you can take a second tablet after at least 2 hours.
