If you suspect possible poisoning, seek emergency medical care immediately.

Call 1-800-222-1222 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 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 any containers with you to the emergency room, if possible.

The patient will be given medications to treat the symptoms and may be forced to vomit. A procedure called gastric lavage may also be performed.

If the patient has convulsions and coma, the outlook for recovery is not good. Those who do recover take several weeks or longer to overcome some of the toxic effects.
