Equanil overdose

Meprobamate is a drug used to treat anxiety. Meprobamate overdose occurs when someone accidentally or intentionally takes more than the normal or recommended amount of this medication.

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 the National Poison Control Center at 1-800-222-1222.

  • Before Calling Emergency

    Determine the following information:

    • Patient's age, weight, and condition
    • Name of the product (ingredients and strength, if known)
    • Time it was swallowed
    • Amount swallowed
  • Poison Control What to Expect at the Emergency Room

    The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national 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 container with you to the hospital, if possible.

    See: Poison control center - emergency number

  • The health care provider will measure and monitor your vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. You may receive:

    • Activated charcoal
    • Breathing support, including tube through the mouth and breathing machine (ventilator)
    • Chest x-ray
    • EKG (heart tracing)
    • Fluids through a vein (by IV)
    • Laxative
    • Medication to treat symptoms
    • Tube from the mouth into the stomach to empty the stomach (gastric lavage)
  • Outlook (Prognosis)

    How well you do depends on the amount of poison swallowed and how quickly treatment is received. The faster you get medical help, the better the chance for recovery.

    With proper care, recovery normally occurs, except possibly in patients with aplastic anemia, because the bone marrow does not produce enough red blood cells.
