The national poison control center hotline is a resource that connects the caller to nurses, doctors and pharmacists who are specially trained to respond to a poison emergency. As of 2015, the phone number is 1-800-222-1222, and it is available 24 hours a day, seven days a week.
In 2013, the 55 poison control centers in the United States received a combined total of 2.2 million calls regarding poisoning emergencies, such as food poisoning, snake bites and carbon monoxide. The hotline provides confidential medical advice and educates callers on in-home treatments, which helps prevent emergency room visits. The local poison control centers work with the American Association of Poison Control Centers to provide alerts on the latest poisoning sources, which include bath salts, liquid nicotine exposure and synthetic marijuana.
