    Phenytoin is a medicine used to treat convulsions and seizures. Phenytoin overdose occurs when someone takes too much of this medicine.

    This is for information only and not for use in the treatment or management of an actual poison exposure. If you have an exposure, you should call your local emergency number (such as 911) or a poison control center at 1-800-222-1222.

    Before Calling Emergency

    Determine the following information:

    • The time it was swallowed
    • The amount swallowed
    • If the medication was prescribed for the patient

    Poison Control

    In the United States, call 1-800-222-1222 to speak with a local poison control center. This hotline number will let you talk to experts in poisoning. They will give you further instructions.

    This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.

    Take the pill container with you to the hospital, if possible.

    What to Expect at the Emergency Room

    The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. Blood tests will be done to check phenytoin levels. Symptoms will be treated as appropriate. The patient may receive:

    • Activated charcoal
    • Laxative
    • Methods to help with breathing
    • Tube through the nose or mouth into the stomach to wash out the stomach (gastric lavage)

    Outlook (Prognosis)

    How well a patient does depends on the severity of the overdose and how quickly treatment is received.
