How should I take vigabatrin?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.
You may take vigabatrin with or without food.
Vigabatrin powder must be mixed only with water, and can be given to the child with a meal. Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.
Anyone taking vigabatrin can develop vision problems that could get worse, even after you stop using this medicine. The more you take vigabatrin, the more likely you are to develop severe vision problems.
You will need a thorough eye exam before you start taking vigabatrin and then every 3 months during treatment, even if your vision seems normal. Eye exams may not fully prevent vision damage, but they will help your doctor decide whether to change your treatment plan. Stay alert to any changes in your vision and report them to your doctor right away.
If you stop taking vigabatrin, you should have another eye exam about 3 to 6 months after your last dose.
It may be more difficult to test vision in a baby or young child. However, your doctor may still prescribe vigabatrin for the child if the benefit of preventing seizures outweighs any risk. Tell the doctor right away if you think your child's vision may be changing.
Call your doctor if your complex partial seizures do not improve after 3 months of treatment, or if your baby's infantile spasms do not improve after 2 to 4 weeks of treatment.
Do not stop using vigabatrin suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Follow your doctor's instructions about tapering your dose.
Store vigabatrin in the original container at room temperature away from moisture and heat.
