Take this medication by mouth as directed by your doctor, usually once daily. You may take it with food if stomach upset occurs. Swallow the tablets whole. Do not crush or chew the tablets. Doing so can release all of the drug at once, increasing the risk of side effects.

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.

Tell your doctor if your condition does not improve.
