The U.S. Food and Drug Administration (FDA) has approved a new, extended-release version of a medicine called Depakote ER. This pill is approved for the acute, or short-term, treatment of manic or mixed episodes in adults with bipolar I disorder. These episodes are distinct periods of abnormally high, expansive, or irritable mood that can be severe. The approval is based on studies showing it can help manage these symptoms. This approval provides a new once-daily oral option for doctors and patients to consider when managing acute mania. It is important to know that the studies supporting its use for this purpose lasted about three weeks. The drug's label states that its effectiveness for long-term use in preventing future manic episodes (more than three weeks) has not been proven in controlled clinical trials. As with any medication, this one has important safety information. The drug carries a serious warning about the risk of birth defects and is not for use in pregnant women or women who could become pregnant and are not using birth control. The most important step for anyone considering this or any new treatment is to have a detailed conversation with their doctor. A doctor can review your full medical history, discuss all potential benefits and risks, and determine if this treatment option is appropriate for your individual care plan.

Depakote ER is a valproate indicated for the acute treatment of manic or mixed episodes associated with bipolar disorder, with or without psychotic features. A manic episode is defined as a distinct period of abnormally and persistently elevated, expansive, or irritable mood, with symptoms such as pressure of speech, motor hyperactivity, reduced need for sleep, flight of ideas, grandiosity, poor judgment, aggressiveness, and possible hostility. A mixed episode meets the criteria for a manic episode in conjunction with those for a major depressive episode. The drug is also indicated for monotherapy and adjunctive therapy of complex partial seizures and simple and complex absence seizures in patients 10 years and older, and for prophylaxis of migraine headaches.
Depakote ER is an extended-release product intended for once-daily oral administration. Tablets should be swallowed whole and not crushed or chewed. For mania, the recommended initial dose is 25 mg/kg/day given once daily. The dose should be increased as rapidly as possible to achieve the lowest therapeutic dose producing the desired clinical effect or desired plasma concentration. In a placebo-controlled clinical trial of acute mania, patients were dosed to a clinical response with a trough plasma concentration between 85 and 125 mcg/mL. The maximum recommended dosage is 60 mg/kg/day. For migraine prophylaxis, the recommended starting dose is 500 mg/day for one week, thereafter increasing to 1,000 mg/day.
The efficacy of Depakote ER for acute mania is based in part on studies of Depakote (divalproex sodium delayed release tablets) and was confirmed in a 3-week trial with patients meeting DSM-IV TR criteria for bipolar I disorder, manic or mixed type, who were hospitalized for acute mania. The label states there is no body of evidence from controlled trials to guide longer-term management beyond the acute manic episode. The effectiveness of valproate for long-term use in mania (more than 3 weeks) has not been demonstrated in controlled clinical trials.
Because of the risk to the fetus of decreased IQ, neurodevelopmental disorders, neural tube defects, and other major congenital malformations, valproate should not be used to treat women with epilepsy or bipolar disorder who are pregnant or who plan to become pregnant unless other medications have failed to provide adequate symptom control or are otherwise unacceptable. Valproate should not be administered to a woman of childbearing potential unless other medications have failed. For prophylaxis of migraine headaches, Depakote ER is contraindicated in women who are pregnant and in women of childbearing potential who are not using effective contraception.
Depakote ER is indicated for the acute treatment (up to 3 weeks) of manic or mixed episodes in bipolar I disorder. The label explicitly states that the effectiveness of valproate for long-term use in mania (more than 3 weeks) has not been demonstrated in controlled clinical trials. Therefore, healthcare providers who elect to use Depakote ER for extended periods should continually reevaluate the long-term risk-benefits of the drug for the individual patient. It is also a treatment option for certain seizure types and for migraine prophylaxis.
