Adults who have complex partial seizures and children who have infantile spasms may be given vigabatrin. This drug can cause serious side effects, so it is generally not used as a first-line treatment. It comes as tablets (for adults) and as a powder that is mixed with water (for children). Possible side effects of this prescription medicine include fatigue, shakiness, and permanent vision loss.
Vigabatrin (Sabril®) is a prescription medication approved to treat certain types of seizures. In adults, it is approved to treat complex partial seizures, when several other treatments have already been tried unsuccessfully. In young children, it is used to treat infantile spasms. Because of the high risk for permanent vision loss, this drug should be used very cautiously and only when the benefits clearly outweigh the risks.
Prescribers and pharmacists must be registered with the special restricted distribution program for this medication (the "SHARE" program) before prescribing or dispensing it. This program is designed to help ensure that only appropriate individuals receive this medication, and that appropriate vision monitoring is performed. Patients must also be enrolled in the SHARE program.
