Sumatriptan

Sumatriptan is used to relieve pain and other symptoms associated with migraines and cluster headaches. Migraines are a severe headache experienced as a throbbing pain at the front or side of the head resulting from dilation of blood vessels in the brain. Migraine headaches are often accompanied by other symptoms such as eyesight changes (visual aura, dark or coloured spots, flickering lights), eye pain, sensitivity to light and sound, dizziness, nausea or vomiting.

What makes Sumatriptan different to an ordinary painkiller?

Sumatriptan will only relieve pain resulting from migraine headaches. It is a type of triptan which works to reverse the changes in the blood vessels in the brain which cause a migraine in addition to alleviating the symptoms.
