How it works
ZomigOnzetra
Zomig (zolmitriptan) is a triptan. It prevents the enlargement of blood vessels in your brain, which causes migraines.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.
