Depakene (valproic acid) is an antiepileptic used to treat various types of seizure disorders. Depakene is sometimes used together with other seizure medications. Depakene is available in generic form. Common side effects of Depakene include diarrhea, constipation, upset stomach, dizziness, drowsiness, weakness, hair loss, blurred/double vision, changes in menstrual periods, enlarged breasts, ringing in the ears, shakiness (tremor), unsteadiness, weight changes, or unusual or unpleasant taste in your mouth. You may have suicidal thoughts while taking Depakene. Tell your doctor if this occurs.

For adults and children over 10 years of age, initial dose of Depakene is 10 to 15 mg/kg/day. The dosage should be increased by 5 to 10 mg/kg/week to achieve optimal response. Maximum optimal dose is usually below 60 mg/kg/day. Cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for depression or anxiety can add to sleepiness caused by Depakene. This drug may also interact with topiramate, tolbutamide, blood thinners, aspirin or acetaminophen, zidovudine, clozapine, diazepam, meropenem or imipenem and cilastatin, rifampin, or ethosuximide. Depakene is not recommended for use during pregnancy. It may cause birth defects. However, since untreated seizures are a serious condition that can harm both a pregnant woman and her fetus, do not stop taking this medication unless directed by your doctor. Your doctor may switch the type of medication you use during pregnancy. This medication passes into breast milk. While there have been no reports of harm to nursing infants, consult your doctor before breast-feeding.

Our Depakene (valproic acid) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Tell your doctor immediately if you or your family/caregiver notice any unusual/sudden changes in your mood, thoughts, or behavior including signs of depression, suicidal thoughts/attempts, thoughts about harming yourself.

Severe (sometimes fatal) brain disorder (encephalopathy) has rarely occurred, particularly in patients with certain metabolic disorders (urea cycle disorders). Tell your doctor immediately if you develop unexplained weakness, vomiting, or sudden mental/mood changes (such as confusion).

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

What is Prescribing information?

The FDA package insert formatted in easy-to-find categories for health professionals and clinicians.

Depakene FDA Prescribing Information: Side Effects
(Adverse Reactions)

SIDE EFFECTS

The following serious adverse reactions are described below and elsewhere in the labeling:

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/Multiorgan hypersensitivity reactions [see WARNINGS AND PRECAUTIONS]

Somnolence in the elderly [see WARNINGS AND PRECAUTIONS]

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice.

Epilepsy

The data described in the following section were obtained using Depakote (divalproex sodium) tablets.

Based on a placebo-controlled trial of adjunctive therapy for treatment of complex partial seizures, Depakote was generally well tolerated with most adverse reactions rated as mild to moderate in severity. Intolerance was the primary reason for discontinuation in the Depakote treated patients (6%), compared to 1% of placebo-treated patients.

Table 3 lists treatment-emergent adverse reactions which were reported by ≥ 5% of Depakotetreated patients and for which the incidence was greater than in the placebo group, in a placebo-controlled trial of adjunctive therapy for the treatment of complex partial seizures. Since patients were also treated with other antiepilepsy drugs, it is not possible, in most cases, to determine whether the following adverse reactions can be ascribed to Depakote alone, or the combination of Depakote and other antiepilepsy drugs.

Table 4 lists treatment-emergent adverse reactions which were reported by ≥ 5% of patients in the high dose Depakote group, and for which the incidence was greater than in the low dose group, in a controlled trial of Depakote monotherapy treatment of complex partial seizures. Since patients were being titrated off another antiepilepsy drug during the first portion of the trial, it is not possible, in many cases, to determine whether the following adverse reactions can be ascribed to Depakote alone, or the combination of Depakote and other antiepilepsy drugs.
