Use "Imigran" as directed by your doctor.
This medication should be taken twice daily, with the doses 7 hours apart. The first dose should preferably be taken in the morning upon waking up, unless directed otherwise by your doctor.
Do not suddenly stop taking Imigran . You may have an increased risk of side effects (e.g., angina attacks). If you need to stop ISMO or add a new medicine, your doctor will gradually lower your dose.
