Household poisons are common products found in homes that can cause poisoning, especially in children, through ingestion, inhalation, or skin contact. Common household poisons include cleaning products, pesticides, plants, and medications. Signs of poisoning may include nausea, vomiting, seizures, trouble breathing, and abnormal skin color. General first aid treatment involves decontamination and calling a poison control center or emergency department for evaluation and further treatment. Proper storage, labeling, and safety measures can help prevent accidental household poisonings.
