Depakote (divalproex sodium) affects chemicals in the body that may be involved in causing seizures. Depakote is used to treat various types of seizure disorders. This medicine is sometimes used together with other seizure medications.

Depakote is also used to treat manic episodes related to bipolar disorder (manic depression), and to prevent migraine headaches. Depakote may also be used for purposes not listed in this medication guide.

Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start taking divalproex sodium and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth as directed by your doctor. You may take it with food if stomach upset occurs. Swallow the tablet whole. Do not crush or chew the tablet, which can irritate the mouth or throat.

The dosage is based on your age, weight, medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day to keep the amount of medication in your blood constant.

If this medication is used for seizures, do not stop taking it without consulting your doctor. Your condition may become worse if the drug is suddenly stopped. Your dose may need to be gradually decreased.

Divalproex sodium does not relieve acute migraine headaches. Take other medications as directed by your doctor for acute attacks.

Inform your doctor if your condition does not improve.

Depakote can cause liver failure that may be fatal, especially in children under age 2 and in people with liver problems caused by certain genetic disorders.

You should not use Depakote if you have liver disease, a urea cycle disorder, low platelet counts, or a genetic disorder such as Alpers' disease or Alpers-Huttenlocher syndrome.

Follow your doctor's instructions about taking this medicine if you are pregnant. Divalproex sodium 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 risks to the baby.

Do not use Depakote to prevent migraine headaches if you are pregnant.
