A migraine is more than a headache. It often lasts longer (up to 72 hours) and is more severe. There are many symptoms of migraines, including nausea, vomiting, and extreme sensitivity to light and sound. The major symptom is moderate to severe pain that typically occurs on one side of your head.
Certain drugs are available to help prevent migraines. Migraine prevention drugs are different from drugs that treat migraines that have already started. You take migraine prevention drugs every day. They help reduce the number of migraines that you have and also help make these migraines less severe. One of these drugs for migraine prevention is called Topamax.
What is Topamax?
Topamax belongs to a class of drugs called anticonvulsants. A class of drugs is a group of drugs that work in a similar way. Although anticonvulsants are used to treat epilepsy, many anticonvulsants are also effective for other conditions, including migraine.
How Topamax works
The exact way that Topamax works to help prevent migraines isn’t known. It is believed that Topamax calms overactive nerve cells in the brain that lead to migraines.
Topamax is taken every day to prevent migraines. You will likely not notice Topamax working right away when you first start using it. It may take a few months for Topamax to reduce the number of migraines you have.
Topamax comes in an oral capsule and an oral tablet. Topamax is a brand name for the drug topiramate. Topamax is also available as a generic drug. Generic drugs usually cost less.
