Sumavel for the treatment of migraine headaches: an introduction
The injection doesn’t need a needle, but uses a burst of gas to shoot the drug underneath the skin.
Sumavel DosePro is for treating adults with acute migraines and cluster headaches. It is not approved for preventing migraines, for preventing other types of headaches or for treating other types of headaches.
Why an injection
Many people who suffer from migraines also experience nausea and vomiting, this makes it difficult to swallow and digest pills. The injection doesn’t require swallowing the medication so that the medicine won’t be vomited. Also, migraine attacks can arise quickly. Injected medication gets into the body quicker than drugs that are taken by mouth and digested in the stomach. Sumavel DosePro’s manufacturer says some people feel relief from migraine symptoms within 10 minutes, with most feeling better in two hours.
How the medicine in Sumavel DosePro works
The active ingredient in Sumavel DosePro, sumatriptan, works by narrowing the blood vessels in the brainstem. It also reduces substances that can trigger migraine symptoms of head pain, nausea, sensitivity to light and sensitivity to sound, and other bothersome symptoms. the medication works best if it is taken as soon as migraine symptoms appear. It will only treat a headache that has started. It will not prevent a migraine attack or reduce the number of attacks you have.
