What is sumatriptan injection?
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 and cluster headaches in adults. Sumatriptan will only treat a headache that has already begun. It 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 is the most important information I should know about sumatriptan injection?
You should not use sumatriptan if you have any history of heart disease or coronary artery disease, blood circulation problems, Wolff-Parkinson-White syndrome, uncontrolled high blood pressure, severe liver disease, circulation problems affecting your intestines, history of a stroke, or if your headache seems to be different from your usual migraine headaches.
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 another migraine headache medicine.
What should I discuss with my health care provider before using sumatriptan injection?
You should not use this medicine if you are allergic to sumatriptan, or if you have:
coronary artery disease, angina (chest pain), blood circulation problems, lack of blood supply to the heart;
a heart disorder called Wolff-Parkinson-White syndrome;
a history of heart disease, heart attack, or stroke, including "mini-stroke";
untreated or or uncontrolled high blood pressure;
severe liver disease;
circulation problems affecting your intestines; 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.
To make sure sumatriptan is safe for you, tell your doctor if you have:

How should I use sumatriptan injection?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended. Overuse of migraine headache medicine can actually make your headaches worse.
Sumatriptan is injected under the skin. You may be shown how to use injections at home. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of used needles and syringes.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Use sumatriptan as soon as you notice headache symptoms, or after an attack has already begun.
Your blood pressure will need to be checked often.
Sumatriptan injection comes in a vial (bottle), an auto-injector or prefilled cartridge to be loaded into an auto-injector syringe, or in a needle-free injector device. Each vial, cartridge, or needle-free device is for one use only.
After using an injection: If your headache does not completely go away after the injection, call your doctor before using a second sumatriptan injection. If your headache goes away and then comes back, you may use a second injection if it has been at least one (1) hour since your first injection. Do not use more than two (2) injections in 24 hours. If your symptoms do not improve, contact your doctor before using any more injections.
Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
Store at room temperature away from moisture, heat, and light. Throw away any unused medicine after the expiration date on the label has passed.
What happens if I miss a dose?
Since sumatriptan is used as needed, it does not have a daily dosing schedule. Call your doctor promptly if your symptoms do not improve after using sumatriptan.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms may include tremors, skin redness, scabs or scaly skin where you injected the medicine, weakness, lack of coordination, breathing problems, blue-colored lips or fingernails, vision problems, seizure (convulsions), or loss of movement in any part of your body.

sumatriptan tablets or nasal spray, almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, zolmitriptan; or
