Antibiotics do help. For treatment of acne, over-the-counter Benzoyl Peroxide Gel or cream is helpful. If desired, a doctor can add an antibiotic gel or cream. If more help is needed, prescription retinoids such as Retin-A or differin (adapalene) gel can be used instead of benzoyl peroxide. Oral contraceptives (for women) and oral antibiotics are options also. If acne is quite severe, a dermatologist may prescribe oral accutane.
It canBut not always. Antibiotics taken by mouth and applied over the skin > may help to reduce acne in some patients, but not in all the patients.
