What is Vigadrone?

Vigadrone is an anti-epileptic medicine, also called an anticonvulsant.

Vigadrone is used in combination with other medications to treat complex partial seizures in adults and children who are at least 10 years old. This medicine powder for oral solution is used to treat infantile spasms in babies and children between the ages of 1 month and 2 years.

Vigadrone can cause serious side effects and should be used only by people who have been unable to control their seizures with several other medications.

Vigadrone may also be used for purposes not listed in this medication guide.


Taking Vigadrone can cause permanent vision loss, even after you stop using Vigadrone. Tell your doctor right away about any changes in your vision. You must have frequent eye exams before, during, and shortly after taking this medicine.

Some babies treated with Vigadrone have had abnormal brain changes seen on magnetic resonance imaging (MRI). Tell any doctor who treats your baby that the child is taking this medicine.

Some people have thoughts about suicide while taking seizure medication. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor.

Before taking this medicine

Some people taking Vigadrone have developed vision problems within weeks to years after starting treatment. Vision loss caused by this medicine may be permanent, and you may notice only mild symptoms at first. Talk to your doctor about this possibility.

Vigadrone is available only from a certified pharmacy under a special program. You must be registered in the program and agree to have vision exams before, during, and shortly after taking this medicine. Be sure you understand the risks and benefits of taking this medicine.

Tell your doctor if you (or the child taking this medicine) have ever had:

  • vision problems;

  • kidney disease;

  • anemia (low red blood cells); or

  • depression, a mood disorder, mental illness, or suicidal thoughts or actions.

Do not start or stop taking seizure medication during pregnancy without your doctor's advice. Having a seizure during pregnancy could harm both mother and baby. Tell your doctor right away if you become pregnant.

How should I take Vigadrone?

You will need a thorough eye exam before you start taking Vigadrone 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 Vigadrone, 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 Vigadrone 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 Vigadrone suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Follow your doctor's instructions about tapering your dose.
