It is available in the form of a tablet that is typically taken twice a day. There is also an injectable form that can be administered intravenously in certain situations. Headaches, dizziness, and nausea are common side effects reported with this medication.

How Does It Work?

Seizures are the result of brief changes in how the brain's electrical system works. It is not known exactly how Vimpat works for treating seizures. Studies suggest that it may work by affecting sodium channels in the brain, preventing the abnormal activity from "firing" and spreading to other parts of the brain. This action helps control seizures.

Clinical Effects

This medication has been thoroughly evaluated in clinical studies. These studies evaluated Vimpat in people with partial-onset seizures whose seizures were not adequately controlled with their current medications. In one study, adding Vimpat significantly reduced seizure frequency by up to 40 percent, compared to only 10 percent in those people who were given a placebo (a "sugar pill" that does not contain any active ingredients) in addition to their regular seizure medications.
