no doesn't sound like it....gluten is the other big trigger, which is much tougher to give up- no wheat, bread, pasta, pizza
before you do that, I would just focus on eating better in general, no sodas, minimize processed foods and just eat whole foods...and try to limit how much white bread you eat, and white pasta
and sometimes when we've overdone the anitbiotics, when you go off and on it can cause issues....Accutane didn't work for me (and antibiotics failed too before that), sadly after 7 months I had no other options but to look at diet and supplements....so I really cleaned up my diet and eliminated dairy and gluten...but I also did the assault with topicals (BP didn't work for me, does for most...lucky me- but I do like salicylic acids and glycolic acids...so there are others you can try) and supplements
for me I keep hitting acne on multiple fronts...I get extraction facials, do regular peels, etc...
you just have to find what is right for you...me personally I would avoid antibiotics...but again you need to find what is right for you
