If you or someone you know has swallowed or breathed in a poison, and you or they have serious signs or symptoms (nausea, vomiting, pain, trouble breathing, seizure, confusion, or abnormal skin color), you must either call an ambulance for transport to a hospital emergency department or call a poison control center for guidance.
