Common Name: ethosuximide

How does Zarontin work?

This medication is used for the management and prevention of certain types of seizures (those caused by absence [petit mal] epilepsy). It may be used at the same time as other medications that are used to control different types of seizures. It helps to control seizures by working in the central nervous system. Your doctor may choose to use a medication for conditions other than the ones listed in these drug information articles. If you're unsure why you are taking this medication, contact your doctor.

How should I use Zarontin?

Adults: The dose of ethosuximide varies according to the needs and age of the person using the medication and their response to treatment. Often a dose of 1 g to 1.5 g daily in divided doses controls seizures in adults. Children: The dose for children three to six years of age is 250 mg daily; for older children, it is 500 mg daily, taken in divided doses. Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor. It is very important that this medication be taken on a regular schedule as prescribed by the doctor. If you miss a dose of this medication, take it as soon as you remember it. If it is almost time for your next dose, skip the missed dose and carry on with your regular schedule. Do not double-up on doses.
