Ethosuximide is used to control absence (petit mal) seizures (a type of seizure in which there is a very short loss of awareness during which the person may stare straight ahead or blink his eyes and does not respond to others). Ethosuximide is in a class of medications called anticonvulsants. It works by reducing abnormal electrical activity in the brain.
Ethosuximide comes as a capsule and as a syrup (liquid) to take by mouth. It is usually taken one or more times a day. Take ethosuximide at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ethosuximide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will probably start you on a low dose of ethosuximide and gradually increase your dose, usually once every 4 to 7 days.
Ethosuximide may help to control your condition, but will not cure it. Continue to take ethosuximide even if you feel well. Do not stop taking ethosuximide without talking to your doctor, even if you experience side effects such as unusual changes in behavior or mood. If you suddenly stop taking ethosuximide, your seizures may worsen. Your doctor will probably decrease your dose gradually.
This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.
