How long does it take for D..

I think ive been on it for about a lil over a week. Does anyone know when it will start clearing up my acne? Is this suppose to make me worse before better? Ive been on differin for almost a month now so that should be taking care of bringing everything out. Just curious..thanks

A couple of weeks; if you have been on it longer than 3 weeks then you have a very bad case because it can take 6-8 weeks for it to become effective. If you have noticed an increase in your acne then you need to contact your doctor; you may be suffering an allergic reaction.

According to Med Help: http://www.medhelp.org/forums/Dermatolog...

"This drug is a reasonable choice, but if any treatment hasn't worked in 2-3 months, it's time to try something else."

According to: http://www.acneway.com/doryx_acne_side_e...

"For controlling acne, Doryx is normally taken over a period of 12 weeks.

If you do not complete the full course prescribed by your doctor, the infection may not clear completely or your symptoms may return.

For treating infections, Doryx is usually taken for one to two weeks"

According to: http://www.aafp.org/afp/20040501/2123.ht...

"Oral Antibiotics. When acne is resistant to topical therapies, oral antibiotics may be used. Oral antibiotics commonly are initial therapy in patients with moderate to severe inflammatory acne. Systemic antibiotics decrease P. acnes colonization and have intrinsic anti-inflammatory effects. First-line oral antibiotics have included tetracycline and erythromycin. Because P. acnes resistance to erythromycin is increasing, this antibiotic is becoming a second-line agent that is used when treatment with tetracycline or other macrolide antibiotics fails or is not tolerated.20
