My wife was cleaning with bleach and ammonia today, and now has a horrible headache what can make it stop?
You absolutely cannot mix bleach and ammonia. It can kill you. She was lucky she only got a headache. Please tell her never to do this again or even to have the two cleaners in the same room.
Please call the Poison Control Center (in the United States National Poison control number 1-800-222-1222) or go to the Emergency Room. The combination of bleach and ammonia creates a poisonous gas and she should have medical attention as soon as possible. These two chemicals should never be combined.
Please take care of her right away.
