How it works
OnzetraAxert
Onzetra (sumatriptan) is a selective serotonin receptor agonist called a triptan. It's believed that migraine headaches happen when blood vessels are too open and allow too much blood in the brain. Onzetra (sumatriptan) tightens the blood vessels, which relieves the pain.Coming soon.
