Medicines to treat armpit rash include a topical steroid for inflammation, an antibiotic cream or ointment for infection, and oral medication, reports WebMD. An antifungal medication may also be recommended by a doctor, depending on the cause of the rash.
Armpit rashes can be caused by eczema, contact dermatitis, seborrheic dermatitis or candida. Along with an armpit rash, other symptoms of these conditions include redness of the affected area, itching, oily patches of scaly skin and swelling, explains Healthline.
Treatment for eczema involves the use of antihistamines to stop itching and an antibiotic if there is infection. Treatment for contact dermatitis requires cleaning the skin with mild soap and cool water, and using histamines. Patients can control seborrheic dermatitis with anti-inflammatory shampoos and oral antifungal medication, explains Mayo Clinic. Candida, which is a yeast infection not a skin disorder, is treated with antifungal cream.
