Introduction
Poisoning occurs when the body is harmed after exposure to a toxic substance. Exposure can happen by swallowing, inhaling, or having contact with a substance through the skin or eyes. Common sources include medications, household chemicals, fumes such as carbon monoxide, plants, pesticides, and certain consumer products. Some exposures can be safely managed with guidance from Poison Control, while others require urgent or emergency medical care.
What Counts as Poisoning
Poisoning includes harmful effects from:
- Medications (prescription and over-the-counter), especially when taken incorrectly
- Household products, such as cleaners and chemicals
- Gases and fumes, including carbon monoxide
- Plants, pesticides, and automotive products
- Small consumer items, such as button batteries and magnets
The effects of a poisoning vary depending on the substance involved and how exposure occurred. Some exposures cause mild symptoms, while others are life-threatening.
Common Poisons in and Around the Home
High-quality evidence consistently identifies the following as common household poisoning risks:
- Medicines and vitamins
- Household cleaners and chemicals
- Laundry detergent packets
- Automotive fluids (such as antifreeze)
- Carbon monoxide from fuel-burning appliances
- Button batteries and small magnets
- Pesticides and certain plants
Most poison exposures occur in the home, particularly among young children.
