Poisonings typically affect the stomach and central nervous system.
If a child suddenly throws up, that can be more difficult to diagnose. Other signs of poison ingestion can be burns around the lips or mouth, stains of the substance around the child's mouth, or the smell of a child's breath. Suspect a possible poisoning if you find an opened or spilled bottle of pills. If you suspect poisoning, remain calm. For medicines, call the nearest poison control center or your physician.
