What is AMERGE used for?

AMERGE is a serotonin (5-HT 1B/1D ) receptor agonist (triptan) indicated for

How does AMERGE work?

How does AMERGE work?

AMERGE is a triptan. It works on receptors in your brain and nervous system that respond to serotonin, a natural chemical in your body that’s thought to play a role in migraines.

When it attaches to the serotonin receptors in the brain, naratriptan tightens the blood vessels in the brain and lessens blood vessel swelling that can cause migraine pain. The medication also stops the release of other pain signals through your nervous system. This helps relieve migraine pain.
