Why is this medication prescribed?

Sumatriptan injection is used to treat the symptoms of migraine headaches (severe, throbbing headaches that sometimes are accompanied by nausea and sensitivity to sound and light). Sumatriptan injection is also used to treat the symptoms of cluster headaches (severe headaches usually on one side of the head or around one eye). Sumatriptan is in a class of medications called selective serotonin receptor agonists. It works by narrowing blood vessels in the brain, stopping pain signals from being sent to the brain, and blocking the release of certain natural substances that cause pain, nausea, and other symptoms of migraine or cluster headaches. Sumatriptan does not prevent migraine attacks or reduce the number of headaches you have.

How should this medicine be used?

Sumatriptan injection comes as a solution (liquid) to inject subcutaneously (just under your skin). It is usually used at the first sign of a migraine headache. If your symptoms improve after you use sumatriptan but return after 1 hour or longer, you may use a second dose of sumatriptan. However, if your symptoms do not improve after you use sumatriptan, do not use a second injection without talking to your doctor. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use sumatriptan exactly as directed. Do not use more or less of it or take it more often than prescribed by your doctor.

Sumatriptan injection comes in a pre-filled auto-injection device and in vials to be used with disposable syringes. If you are using vials of sumatriptan injection, your doctor or pharmacist will tell you what type of syringe you should use. Do not use any other type of syringe because you may not get the right amount of medication.

You can inject your sumatriptan in the outer side of your thigh or upper arm. Do not inject sumatriptan through clothing. Never inject sumatriptan into a vein or muscle.

You may use your first dose of sumatriptan injection in a doctor's office or other medical facility where you can be monitored for serious reactions. Carefully read the instructions that come with your device, and ask your doctor or pharmacist to show you how to use it.

Call your doctor if your headaches do not get better or occur more frequently after using sumatriptan injection.

If you use sumatriptan more often or for longer than the recommended period of time, your headaches may get worse or may occur more frequently. You should not use sumatriptan injection or take any other headache medication for more than 10 days per month. Call your doctor if you need to use sumatriptan injection to treat more than four headaches in 1-month period.

Do not use prefilled injection devices or vials of sumatriptan injection more than once. Dispose of used syringes in a puncture-resistant container. Ask your doctor or pharmacist how to dispose of the puncture-resistant container.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
