What is stiripentol?

Stiripentol is used to treat seizures associated with Dravet syndrome. Dravet syndrome is a rare chronic form of epilepsy that begins in the first year of life and causes frequent or prolonged seizures.

Stiripentol is for use in adults and children at least 2 years old who also take another medicine called clobazam.

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

Important Information

Stiripentol can cause drowsiness, especially if you also drink alcohol or take other medicines that can make you sleepy. Tell your doctor about all your current medicines and any you start or stop using. Avoid driving or hazardous activity until you know how stiripentol will affect you.

A small number of people have thoughts about suicide while taking stiripentol. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor.

Do not start or stop taking seizure medication during pregnancy without your doctor's advice. Stiripentol may harm an unborn baby, but having a seizure during pregnancy could harm both mother and baby. The benefit of preventing seizures may outweigh any risk. Tell your doctor right away if you become pregnant.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Always take stiripentol during a meal.

Swallow the capsule whole and do not crush, chew, break, or open it.

You may need to take two different strengths of stiripentol capsules to make up your correct dose. Follow your doctor's dosing instructions very carefully.

Take the capsule with a full glass of water.

Dissolve one packet of the powder in 3 ounces of water. Stir and drink this mixture right away. Add at least 1 ounce more water to the glass, swirl gently and drink right away.

Stiripentol doses are based on weight. Your dose needs may change if you gain or lose weight.

Stiripentol can cause nausea, vomiting, loss of appetite, and weight loss. Weigh yourself often, and tell your doctor if you begin to lose weight. Your medication doses may need to be adjusted.

Do not change your stiripentol or other seizure medication doses or dosing schedules without your doctor's advice.

Decreased appetite and weight loss may affect growth in a child. Your doctor will need to check your child's growth rate at regular intervals.

Stiripentol can increase your risk of bleeding or infection. You will need frequent medical tests.

Store at room temperature away from moisture, heat, and light.

Do not stop using stiripentol suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Follow your doctor's instructions about tapering your dose.
