Will daily spraying of 75% alcohol in a room cause poisoning?

Generally speaking, whether daily spraying of 75% alcohol in a room can cause poisoning depends on the specific circumstances. It may not lead to poisoning, but poisoning could occur under certain conditions. Appropriate measures should be taken based on individual situations. The details are as follows:

1. No poisoning

Alcohol at a concentration of 75% is commonly used as medical-grade alcohol. Spraying it can effectively disinfect and kill bacteria and viruses. When used properly under medical guidance, it generally does not harm the body, and daily use typically will not result in poisoning.

2. Possible poisoning

75% alcohol is usually used for skin disinfection or sterilizing medical instruments. Due to its high concentration, it is strongly irritating. If sprayed daily in a room and accidentally ingested, adverse reactions may occur—such as irritation to the throat causing pain, nausea, or other discomforts. Inhaling excessive amounts may even trigger alcohol poisoning.

If symptoms of poisoning occur, treatment under a doctor's supervision with medications such as loratadine tablets, cetirizine hydrochloride capsules, or losartan potassium and hydrochlorothiazide tablets may be necessary to aid recovery.
