As little as three grams of ferrous sulfate has proved fatal in children. Serious shock may ensue (as late as twenty to forty-eight hours afterward) because of the corrosive effect of the poison on the gastrointestinal tract. Vomiting, abdominal pain, diarrhea due to the local caustic action, weakness, rapid pulse, pallor, and cyanosis may develop rapidly.
WHAT TO DO
While waiting for professional help, have the victim drink a demulcent such as milk or milk of magnesia. Induce vomiting by syrup of ipecac. (see To Induce Vomiting) under PROCEDURE E on THIS POST.
Shock should be treated actively in the hospital emergency room.
