I am currently useing a bz cream for my face and have always used doxycycline for my acne too. This is a pill that i have always liked using and like the results. But someone told me i should take some breaks from pills every now and then like 2 months for a 2 week break. This is suppose to keep my body from getting use to it. But when i get off the pill my acne intends to come back. Maybe i just have to suck it up for a couple weeks and then continue using the pilll after the break. Any suggestions on what i should do or any info i could get on this subject. This can go for any acne pill no just doxycycline.
