Stop using antibiotics or not

Patient: I’ve been taking Doxycline antibiottics for about 3 weeks now and I have not noticed much of a difference. I still get acne regularly and my acne was less mild a couple months ago. I feel like I should completely stop taking the pills because it seems like it has more cons than pros. Although, I heard that if you stop antibiotics you will break out severly. Is there any way I can prevent that or should I just keep trying the pills?
