A person usually doesn't go home until after the period of dangerous side effects has passed. The person may have a sore throat for a day or two. If stomach pumping is done because of a poisoning, the home should be checked for poisons such as chemicals, cleansers, drugs, supplements, tobacco, and other toxic substances. These materials should be clearly marked and stored where children cannot get them.
Stomach pumping can cause a person with a strong gag reflex to vomit. This can lead to aspiration, or breathing in the contents of the stomach. This can cause aspiration pneumonia. Nosebleeds may occur when the tube is inserted through the nose.
