Imitrex Inj

Imitrex Inj Uses

Sumatriptan is used to treat migraines and cluster headaches. It helps to relieve pain and other symptoms of migraines/headaches including sensitivity to light or sound, nausea, and vomiting. Prompt treatment allows you to get back to your normal routine and may decrease your need for other pain medications. It does not prevent future migraines/headaches or reduce how often you may get a headache.

Sumatriptan belongs to a group of drugs called triptans. It affects a certain natural chemical (serotonin) that constricts blood vessels in the brain. It may also block other pain pathways in the brain.

How To Use Imitrex Inj

Read the Patient Information Leaflet available from your pharmacist before you start using sumatriptan and each time you get a refill. Ask your doctor or pharmacist if you have any questions.

Inject the medication just below the skin as soon as the symptoms of your migraine/headache appear. Before injecting each dose, clean the injection site with rubbing alcohol. This medication should never be injected directly into a vein (IV) or into a muscle (IM).

This medication can be injected either by using a syringe and needle or with an auto-injector. Learn all preparation and usage instructions in the product package. If any of the information is unclear, consult your doctor or pharmacist. Make sure you understand the correct technique for injection and how to properly dispose of needles, syringes and unused medication.

If there is no improvement in your symptoms, do not take any more doses of this medication before talking to your doctor. If your symptoms are only partly relieved, or if your headache comes back, you may use a second injection after one hour or as directed by your doctor. Do not use more than 2 injections (12 milligrams) in a 24-hour period. Do not reuse the syringe. If you are using an auto-injector device, it may be re-used.

If your symptoms are only partly relieved, and 2 hours have passed since the injection, you may take a sumatriptan tablet by mouth instead of using a second injection. Do not take more than 200 milligrams of this medication by mouth, or a maximum of 3 doses (2 by mouth and 1 injection), in a 24-hour period.

If you have never taken this medication before and you have risk factors for heart disease (see Precautions), you may need to be monitored for rare but serious side effects (e.g., chest pain) when you take the first dose. Your doctor may ask you to take the first dose in the office.

Your dosage is based on your medical condition and response to therapy. Tell your doctor if your condition does not improve or worsens.
