What is the most important information I should know about valproic acid (Depakene)?

Valproic acid can cause liver failure that may be fatal, especially in children under age 2 and in people with liver problems caused by certain genetic disorders.

You should not use valproic acid if you have liver disease, a urea cycle disorder, or a genetic disorder such as Alpers' disease or Alpers-Huttenlocher syndrome.

Follow your doctor's instructions about taking this medicine if you are pregnant. Valproic acid may harm an unborn baby, but having a seizure during pregnancy could harm both mother and baby. The benefit of preventing seizures may outweigh any risks to the baby.

Do not use valproic acid to prevent migraine headaches if you are pregnant.

Call your doctor at once if the person taking this medicine has signs of liver or pancreas problems, such as: loss of appetite, upper stomach pain (that may spread to your back), ongoing nausea or vomiting, dark urine, swelling in the face, or jaundice (yellowing of the skin or eyes).

Do not stop using valproic acid without your doctor's advice. Stopping suddenly may cause a serious, life-threatening type of seizure.

What should I discuss with my healthcare provider before taking valproic acid (Depakene)?

You should not use valproic acid if you are allergic to it, or if you have:

  • liver disease;
  • a urea cycle disorder; or
  • a genetic mitochondrial (MYE-toe-KON-dree-al) disorder such as Alpers' disease or Alpers-Huttenlocher syndrome, especially in a child younger than 2 years old.

Valproic acid can cause liver failure that may be fatal, especially in children under age 2 and in people with liver problems caused by a genetic mitochondrial disorder.

Tell your doctor if you have ever had:

  • liver problems caused by a genetic mitochondrial disorder;
  • depression, mental illness, or suicidal thoughts or actions;
  • a family history of a urea cycle disorder or infant deaths with unknown cause; or
  • HIV or CMV (cytomegalovirus) infection.

Some young people have thoughts about suicide when first taking valproic acid. Your doctor should check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.

Do not use valproic acid to prevent migraine headaches if you are pregnant.

If you take valproic acid for seizures or manic episodes: This medicine can harm an unborn baby, and may affect cognitive ability (reasoning, intelligence, problem-solving) later in the child's life. However, having a seizure during pregnancy could harm both the mother and the baby. Do not start or stop taking the medicine during pregnancy without your doctor's advice.

Use effective birth control while using valproic acid, and tell your doctor right away if you become pregnant. Tell your doctor if you start or stop using hormonal contraception that contains estrogen (birth control pills, injections, implants, skin patches, and vaginal rings). Estrogen can interact with valproic acid and make it less effective in preventing seizures.

Seizure control is very important during pregnancy. The benefit of preventing seizures may outweigh any risks posed by taking valproic acid. There may be other seizure medications that can be more safely used during pregnancy. Follow your doctor's instructions about taking valproic acid while you are pregnant.

It may not be safe to breast-feed while using this medicine. Ask your doctor about any risk.
