A 21-year-old male asked:
how long does it take to start seeing improvement in acne while using bactrim (sulfamethoxazole and trimethoprim) antibiotic?

Dr. Arlo Miller answered
15 years experience Dermatology
Weeks : Nothing works overnight for acne, except perhaps steroid injections into individual lesions.
You might get lucky and see improvement in just a week, but you should be prepared to give it 6 weeks.
