Zomig® (zolmitriptan)

Zomig® (zolmitriptan) is a medicine used to treat migraines in adults. It is a type of drug called a serotonin receptor agonist. Zomig provides symptom relief, but it does not prevent future migraines.^1,2

Zomig was first approved as a swallowable tablet. It is now also available in a dissolving tablet (Zomig ZMT) and as a nasal spray. The tablets and dissolving tablets are available in generic forms under the name zolmitriptan.^3,4

What are the ingredients in Zomig?

The active ingredient in Zomig is zolmitriptan.²

How does Zomig work?

Zomig is classified as a triptan. This means it specifically targets (5‑HT)1B/1D serotonin receptors. The zolmitriptan in Zomig binds (sticks) to these receptors. Researchers believe that Zomig works by binding to these receptors in neurons (nerve cells) and on blood vessels in the brain. This causes the blood vessels to constrict and blocks chemicals that would increase inflammation.^1,2

Zomig also reduces substances that trigger head pain and may be involved in migraine, such as nausea, sensitivity to light, and sensitivity to sound. Zomig works best when it is taken at the first sign of a migraine. It does not prevent a migraine or reduce the number of migraines you have.^2,3

Zomig can be used for migraines with or without aura. Aura is the visual or sensory symptoms some people with migraines experience before the head pain.²
