i'm taking antibiotics rite now but it not doxycycline it is septra ds. i take 2 time a day and it made me break out alot too. so far i'm on my 2nd week of taking it my dermatologist say i should see result in 3 weeks. i was also wondering how does these antibiotics pills treat acne ? does it make you break out for the first couple week and then your face start clearing after the 3rd weeks.
