In brief: Not the best choice

An antibiotic must never be used as sole therapy for acne.
Cystic acne may be helped by antibiotic treatment plus a topical agent such as benzoyl peroxide, but usually requires isotretinoin. You've heard the internet scare stories but most people who try this Rx -- which isn't for the faint-hearted -- are very glad. Acne's a grave personal / professional liability; ask if this is right for you.
