Several tetracyclines have failed ( doxy, mino, solodyn) as have topicals (evoclin, triaz, duac, retin-a, aczone. I started Bactrim DS 3 weeks ago (2x daily) but I am still experiencing new cysts on my back ( none on my face/chest).
How soon should this stop them? Should I still be getting new cysts 3 weeks in ? They are causing raised scars on my chest & back. I am classified as 'moderate cystic acne with very mild rosacea'. My derm has me taking it until July and re-evaluating at that time.
