Sumatriptan is used for:
The treatment of migraine headaches with or without aura (eg, flashing lights, wavy lines, dark spots). It may also be used for other conditions as determined by your doctor.
Sumatriptan is a serotonin 5-HT 1 receptor agonist ("triptan"). It works by narrowing blood vessels in the brain, which helps to relieve migraines.
Do NOT use Sumatriptan if:
- you are allergic to any ingredient in Sumatriptan
- you have a history of ischemic heart disease (eg, angina, heart attack), coronary artery disease (CAD), other moderate to severe heart problems, brain blood vessel disease (eg, stroke, transient ischemic attack), or other blood vessel disease (eg, Raynaud syndrome, ischemic bowel disease)
- you have uncontrolled high blood pressure or severe liver problems
- you have certain types of migraines (eg, hemiplegic, basilar)
- you are taking or have taken a monamine oxidase inhibitor (MAOI) (eg, phenelzine) within the past 14 days
- you have used certain other migraine medicines within the past 24 hours (eg, an ergot derivative [eg, dihydroergotamine, methysergide], another serotonin 5-HT 1 receptor agonist [eg, eletriptan, rizatriptan])
- you are taking sibutramine
Contact your doctor or health care provider right away if any of these apply to you.
How to use Sumatriptan:
Use Sumatriptan as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- An extra patient leaflet is available with Sumatriptan. Talk to your pharmacist if you have questions about this information.
- Take Sumatriptan by mouth with or without food.
- Swallow Sumatriptan whole. Do not break, crush, or chew before swallowing.
- It is best to take a dose of Sumatriptan as soon as you notice symptoms of a migraine attack.
- If your migraine symptoms go away and then come back, or if you have a partial response to the first dose, you may take a second dose as directed by your doctor. Wait at least 2 hours between doses.
- If your symptoms do not improve after the first dose, do not take a second dose for the same attack. Contact your doctor.
- Do not take more than the amount prescribed by your doctor in a 24-hour period or treat more than 4 headaches within 30 days without checking with your doctor.
- If you miss a dose of Sumatriptan and you still have a headache, follow your doctor's dosing instructions. Contact your doctor immediately if you are unsure of what to do if you miss a dose. Do not take Sumatriptan more often than prescribed. Do not take 2 doses at once.
