This is a free and confidential service. All local poison control centers in the U.S. 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.

The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. The patient may receive:

• Fluids by IV
• Medicines to treat symptoms
• Activated charcoal
• Laxative
• Medicine (antidote) to reverse the effect of the poison

Recovery depends on the nature of the damage done by the overdose. Survival past 2 weeks is usually a good sign, with full recovery taking 4 to 8 weeks.
