Antibiotics are moderately effective for acne and are frequently used for acne treatment. They are often prescribed for months or years, because acne is a chronic skin condition. However, many physicians are concerned about the use of antibiotics for acne, mainly because of reports of increasing rates of bacterial resistance to antibiotics.
Bacterial resistance and serious infections including cellulitis, pneumonia, tuberculosis and diarrhoeal illnesses are a global threat. New, more expensive antibiotics are often less well tolerated than older agents and are unavailable in many countries. Very few new antibiotics are being discovered or brought to market.
If you are prescribed antibiotics for acne, discuss these concerns with your doctor. Make sure your acne treatment is reviewed regularly. It's best to limit a course of antibiotics to 3 months, if possible. Apply topical benzoyl peroxide and/or a topical retinoid to areas affected by acne while on antibiotics and after they have been stopped. Find out if other, non-antibiotic treatment might be suitable for you.
