How to save yourself from poisoning
Call for help.
If you suspect that you have been poisoned, it is key to call for help immediately. The time delay between the poisoning and treatment can mean the difference between life and death in some cases.
Therefore, call emergency medical services (911) immediately, or your local poison control centre for advice on how best to proceed. The phone number for the poison control centre in the united states is 1-800-222-1222.
