I have moderate acne, and my derm put me on 50 mg of doxycycline ONCE a day. this seems really low. will it actually work or is it better to take 100 mg?
I'm just worried that if I start out at a low dose, it'll never be effective.
any ideas?

Well I have fairly moderate acne and I take 100 mg 2x daily. 50 mg seems low to me!
By the way, after using antibiotics since August, my acne is still here... Hopefully it'll work better for you!
