Generic Name: valproic acid (Oral route)
Hepatotoxicity (some cases fatal), usually occurring during the first 6 months of treatment, has been reported in patients receiving valproate and its derivatives. Children younger than 2 years and patients with hereditary mitochondrial disease are at a considerably increased risk of developing fatal hepatotoxicity. Use is contraindicated in patients with known mitochondrial disorders caused by mitochondrial DNA polymerase gamma (POLG) mutations and in children younger than 2 years in which mitochondrial disorder is clinically suspected. Failure of other anticonvulsants is the only indication for valproate use in patients older than 2 years with hereditary mitochondrial disease. Perform POLG mutation screening as clinically indicated. Monitor patients closely and perform liver function tests prior to therapy and at frequent intervals thereafter, especially during the first 6 months. Valproate can impair cognitive development with prenatal exposure and produce major congenital malformations, particularly neural tube defects (eg, spina bifida). Valproate should not be administered to a woman of childbearing potential unless the drug is essential to the management of her medical condition. Life-threatening pancreatitis has been reported in both children and adults receiving valproate. If pancreatitis is diagnosed, valproate should ordinarily be discontinued .Oral route(Tablet, Delayed Release;Capsule, Delayed Release;Tablet, Extended Release)

Before Using Depakene
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of valproic acid in children. However, safety and efficacy have not been established in children with epilepsy younger than 10 years of age, and in children with migraine younger than 12 years of age. Because of valproic acid's toxicity, use in children younger than 2 years of age requires extreme caution.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of valproic acid in the elderly. However, elderly patients are more likely to have unwanted effects (eg, tremors or unusual drowsiness), which may require an adjustment in the dose for patients receiving valproic acid.
