Sumagrain is used to treat acute migraine headaches. It works to reduce pain and headache symptoms by affecting the blood vessels in the brain, as it helps to narrow the dilated blood vessels that are believed to play a role in the onset of migraine attacks. It also helps to reduce the release of some chemicals that cause pain and inflammation during an attack. It is preferable to use
Sumagrain as soon as migraine symptoms begin to achieve the best effectiveness. It is not used to prevent migraine attacks or as a long-term treatment for this condition, but is intended only to relieve symptoms during an attack.
