Divalproex Sodium

Depakote™, Depakote ER™

What It's For & How To Take

Divalproex is an anti-seizure medication. This medication works by decreasing nerve signals in the brain. This process helps restore normal nerve activity.

Divalproex is used to prevent and control seizures. This medication is also used to help stabilize the mania portion of bipolar disorder.

Divalproex is sometimes used to prevent or decrease the frequency of migraine headaches. Divalproex will not treat a migraine once it is occurring. If you already have a migraine, treat it as directed by your healthcare provider.

This medication is sometimes used to treat other conditions. Talk with your doctor or pharmacist if you are prescribed this medication to treat something that is not listed here.

Divalproex comes in two forms, a delayed release form called Depakote™ and an extended release form called Depakote ER™. These two products are not interchangeable and are not bioequivalent. When changing from one product to another, the dose will need to be adjusted. Depakote™ is usually taken 2-3 times daily while Depakote ER™ is usually taken once daily unless directed otherwise by your doctor.

This medication may be taken with food. Take your dose at evenly spaced intervals in order to maintain a constant level of medication in your body. Swallow the tablets whole. Do not crush or chew the tablet because it will irritate the throat and change the delayed or extended release mechanism of the medication.

Your dose is based on your condition, weight, and how well you respond to treatment. Do not stop taking this medication without talking with your doctor first. Some conditions may worsen if this medication is stopped quickly.

If you forget to take a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.
