Different medicated soaps contain different chemicals, each of which can have an entirely different action. Antibiotics present in the soap can be expected to change the bacterial flora on the surface of the body and may lead to overgrowth of fungi. It is theoretically possible, though rare, for the chemical in the soap to be absorbed from mucous membrane or breach in the skin. It then reaches other parts of the body through blood, to produce effect at remote sites. However get it checked up.
