Warnings:

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), and neurodevelopmental disorders. Valproate is contraindicated for prophylaxis of migraine headaches in pregnant women and in women of childbearing potential who are not using effective contraception. Valproate should not be administered to a woman of childbearing potential unless other medications have failed to provide adequate symptom control or are otherwise unacceptable. In such situations, effective contraception should be used. Life-threatening pancreatitis has been reported in both children and adults receiving valproate. Cases have occurred shortly after initiation as well as several years after use. If pancreatitis is diagnosed, valproate should ordinarily be discontinued .

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 divalproex sodium in patients older than 2 years with hereditary mitochondrial disease.

Classifications:

Therapeutic—

Anticonvulsant

Pharmacologic—

Histone Deacetylase Inhibitor

Chemical—

Valproic Acid (class)

Uses of This Medicine:

Valproic acid is used to treat certain types of seizures (epilepsy). This medicine is an anticonvulsant that works in the brain tissue to stop seizures.

Valproic acid is also used to treat the manic phase of bipolar disorder (manic-depressive illness), and helps prevent migraine headaches.

This medicine is available only with your doctor's prescription.

Before Using This Medicine:

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:

Allergies—

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. 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.

Children—

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.

Older adults—

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.

Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using the medicine, tell your doctor right away.

It is very important to take folic acid before getting pregnant and during early pregnancy to lower chances of harmful side effects to your unborn baby. Ask your doctor or pharmacist for help if you are not sure how to choose a folic acid product.

Liver problems may occur while you are using this medicine, and some may be serious. Check with your doctor right away if you are having more than one of these symptoms: abdominal or stomach pain or tenderness, clay-colored stools, dark urine, decreased appetite, fever, headache, itching, loss of appetite, nausea and vomiting, skin rash, swelling of the feet or lower legs, unusual tiredness or weakness, or yellow eyes or skin.

Valproic acid may cause some people to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. If you notice any of these side effects, tell your doctor right away.

Valproic acid may cause serious allergic reactions affecting multiple body organs (eg, liver or kidney). Check with your doctor right away if you have the following symptoms: a fever, dark urine, headache, rash, stomach pain, swollen lymph glands in the neck, armpit, or groin, unusual tiredness, or yellow eyes or skin.

Check with your doctor right away if you are having unusual drowsiness, dullness, tiredness, weakness or feelings of sluggishness, changes in mental status, low body temperature, or vomiting. These may be symptoms of a serious condition called hyperammonemic encephalopathy.

Valproic acid may cause some people to become dizzy, lightheaded, drowsy, or less alert than they are normally. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

Do not stop using this medicine without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping completely. This may help prevent worsening of seizures and reduce the possibility of withdrawal symptoms.

Before you have any medical tests, tell the medical doctor in charge that you are taking this medicine. The results of some tests may be affected by this medicine.
