Zarontin is a prescription drug approved by the U.S. Food and Drug Administration (FDA) to control absence (petit mal) seizures in epilepsy. Zarontin is frequently prescribed for children with childhood absence epilepsy. Zarontin is also referred to by its drug name, ethosuximide.
Zarontin is an anticonvulsant, or in other words, a drug used to prevent and control seizures. It is believed to work in cases of epilepsy by inhibiting nerve signals in the brain.

Do not stop taking Zarontin suddenly. If you decide to stop taking Zarontin, consult your physician for a plan to reduce your dosage gradually.
Zarontin should be taken exactly as prescribed by a physician.
