Divalproex Sodium is available as a 125 mg, 250 mg and 500 mg delayed-release oral tablet.

Divalproex Sodium is an antiepileptic and is used to treat bipolar disorder,
seizures (focal impaired awareness seizure, absence seizure), and migraine prevention.

Divalproex Sodium is an antiepileptic. It’s not exactly clear how this medication works to prevent migraines or treat mania episodes in bipolar. But in order to control seizures, Divalproex Sodium signals your brain to make more of a chemical called gamma-aminobutyric acid (GABA). GABA helps to reduce the bursts of activity in your brain, which prevents seizures.

Divalproex Sodium is typically taken by mouth in divided doses up to a maximum dose of 1000 mg per day.
