My doctor has prescribed Clotrimazole Cream USP, 1% for a foot fungus. I am allergic to any product which has CHLORO in it. After picking up the product, I read the papers inside and it says the antifungal agent having the chemical name (1-(o-Chloro-a,a-diphenyylbenzyl)imidazole) which alert me. I have not opened the tube yet and feel I should consult with my doctor before using the product. Do you agree?
