If you suffer from migraine headaches, your healthcare provider may prescribe Zomig. This medication is not designed to prevent migraines, but it can help to relieve migraine symptoms as they occur. Zomig works by narrowing blood vessels in the head that become dilated during a migraine. The medicine comes as a tablet, a nasal spray, and an orally disintegrating tablet that quickly dissolves in the mouth. As with any medication, there are possible side effects, including dizziness, abnormal sensations (such as tingling), and nausea.
In addition to Zomig tablets, Zomig® Nasal Spray and Zomig ZMT® (orally disintegrating tablets that dissolve in the mouth) are also available.
(Click Zomig Uses for more information on what the medication is used for, including possible off-label uses.)
Who Makes Zomig?
It is made by Impax Pharmaceuticals.
How Does It Work?
Zomig is part of a class of migraine medications called 5-HT agonists (or more commonly known as "triptans"). During a migraine headache, some of the blood vessels in the head become dilated (wider than they usually are). This medication works by narrowing these blood vessels, helping them return to their normal state. This action helps to relieve migraine symptoms.
In previous studies, 59 percent to 67 percent of people with migraines had no (or mild) pain within two hours of taking Zomig tablets, compared to only 16 percent to 44 percent of people who did not take it. Similar results were seen in studies of Zomig ZMT tablets and Zomig Nasal Spray.
