Description

Valproic acid (also called Depakote® or Depakene®) is used to prevent seizures. It is also used to treat some psychiatric illnesses and to prevent migraine headaches. Valproic acid is available in several forms taken by mouth:

Special instructions

  • Do not stop taking this medicine until your doctor tells you to do so. If you stop taking it without being told, your chances of having a seizure may increase.
  • Store valproic acid at room temperature.
  • The doctor will slowly increase your dose of valproic acid when you first begin taking it.
  • This medicine may cause you to feel dizzy and drowsy. Do not operate heavy equipment or drive a motor vehicle until you see how this medicine will affect you.
  • If you develop a rash after starting valproic acid, you may be allergic to this medicine. Call your doctor, pharmacist, or nurse right away.
  • It is very important that you take valproic acid exactly as directed. This will keep the blood levels constant during the day and night. If you miss a dose, follow these guidelines:
    • If the next dose is not due for at least 4 hours, take the missed dose right away.
    • If the next dose is due in less than 4 hours, do not take the missed dose. Take the next dose at the scheduled time. Never take a double dose unless your doctor or pharmacist tells you to do so.
