sumatriptan (oral/nasal)

What is the most important information I should know about sumatriptan?

Do not use this medicine if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, or tranylcypromine.

Do not use sumatriptan within 24 hours before or after using any other migraine headache medicine.

What is sumatriptan?

Sumatriptan is a headache medicine that narrows blood vessels around the brain. Sumatriptan also reduces substances in the body that can trigger headache pain, nausea, sensitivity to light and sound, and other migraine symptoms.

Sumatriptan is used to treat migraine headaches in adults. Sumatriptan will only treat a headache. This medicine will not prevent headaches or reduce the number of attacks.

Sumatriptan should not be used to treat a common tension headache or a headache that causes loss of movement on one side of your body. Use this medicine only if your condition has been confirmed by a doctor as migraine headaches.

Sumatriptan may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before using sumatriptan?

• heart problems, or a stroke (including "mini-stroke");
• coronary artery disease, angina (chest pain), blood circulation problems, lack of blood supply to the heart;
• circulation problems affecting your legs, arms, stomach, intestines, or kidneys;
• a heart disorder called Wolff-Parkinson-White syndrome;
• uncontrolled high blood pressure;
• severe liver disease; or
• a headache that seems different from your usual migraine headaches.

Do not use sumatriptan if you have used an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, tranylcypromine, and others.

Be sure your doctor knows if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson's disease, serious infections, or prevention of nausea and vomiting. These medicines may interact with sumatriptan and cause a serious condition called serotonin syndrome.

Tell your doctor if you have ever had:

• liver or kidney disease;
• epilepsy or other seizure disorder;
• high blood pressure, a heart rhythm disorder; or
• risk factors for coronary artery disease (such as diabetes, menopause, smoking, being overweight, having high blood pressure or high cholesterol, having a family history of coronary artery disease, or being older than 40 and a man).

How should I use sumatriptan?

Use sumatriptan as soon as you notice headache symptoms. Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

You may receive your first dose in a hospital or clinic setting to quickly treat any serious side effects.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

After using sumatriptan: If your headache does not completely go away, or goes away and comes back, use a second dose if it has been at least 2 hours since your first dose.

Never use more than your recommended dose. Overuse of migraine headache medicine can make headaches worse. Tell your doctor if the medicine seems to stop working as well in treating your migraine attacks.
