Physician decision: This is in common use for acne in various protocols. The dose/frequency & duration is determined by the prescribing physician after a thorough review of the case.

2-3 weeks: You may wish to add topical Clindamycin with or without a retinoic acid derivative. If you do not get a satisfactory result after 6 weeks, consider a dermatology consult for the big guns -- more unpleasant and more dangerous but hugely effective. This is the 21st century and nobody needs to have unwanted acne. Good luck.

Can doxycycline treat acne? How long it's going to take to treat acne?

Not by itself: I see that you also have thrush and if you do, perhaps this isn't the best time to start on doxycycline. I trust you have been using topical benzoyl peroxide and this is the basis of your treatment. Usually you see good results in a few weeks with an effective anti-acne combination. Spironolactone, the birth control pill, or topical clindamycin are other possibilities.
