Sulpho-Lac Soap may also be used for purposes not listed in this medication guide.

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Do not take by mouth. Topical medicine is for use only on the skin or scalp.

Wash your hands before and after applying Sulpho-Lac Soap lotion. Also clean and gently dry the skin area to be treated.

Apply a thin layer of sulfur topical lotion to the affected skin up to 3 times per day. Rub in gently. Apply the lotion less often if your skin becomes overly dry or peels.

Do not cover treated skin with a bandage. Heat or bandaging can increase the amount of drug absorbed through your skin and may cause harmful effects.
