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.

• Activated charcoal
• Fluids through an IV
• Medicines to treat symptoms

Outlook (Prognosis)

Recovery is very likely, since the ingredients are generally considered nontoxic.
