Summary
Vigabatrin is used to treat epilepsy, which is a condition causing seizures. It is particularly effective for complex partial seizures, which are seizures affecting a specific part of the brain, and infantile spasms, which are seizures occurring in young children.
Vigabatrin works by increasing the levels of GABA, which is a neurotransmitter that calms nerve activity in the brain. This helps reduce the frequency of seizures by quieting the overactive signals that cause them.
Vigabatrin is usually taken as a tablet twice daily, once in the morning and once in the evening. The starting dose for adults is typically 500 mg twice daily, and the dose may be adjusted by the doctor based on individual needs.
Common side effects of Vigabatrin include fatigue, which is feeling very tired, dizziness, which is feeling lightheaded, and weight gain. These effects can vary from person to person and should be discussed with a doctor if they occur.
Vigabatrin can cause vision problems, including permanent vision loss, so regular eye exams are crucial. It should not be used by people with a history of vision problems. Mood changes, such as depression, which is feeling very sad, can also occur.
