Summary
Felbamate is used to treat seizures, which are sudden, uncontrolled electrical disturbances in the brain. It is particularly effective for Lennox-Gastaut syndrome, which is a severe form of epilepsy, and partial seizures, which affect only one part of the brain. It is often used when other medications have not worked.
Felbamate works by affecting brain chemicals, which are substances that help transmit signals in the brain. It blocks certain signals that can trigger seizures, which are sudden bursts of electrical activity in the brain. This helps reduce the frequency and severity of seizures.
Felbamate is usually taken by mouth, which means swallowing it as a pill or liquid. Adults typically start with 1,200 mg per day, divided into three or four doses. The maximum dose is 3,600 mg per day. For children, the dose is based on body weight.
Common side effects of felbamate include insomnia, which is trouble sleeping, nausea, which is feeling sick to your stomach, and dizziness, which is feeling lightheaded or unsteady. These effects vary from person to person and may not affect everyone.
Felbamate can cause serious blood disorders, which are problems with the cells in your blood, and liver problems, which affect how your liver works. Regular blood tests are needed to monitor your health. It should not be used if you have a history of these conditions or are allergic to felbamate.
