Bactrin is a very powerful antibiotic. It will probably help her acne, but if she should get a more serious infection at some point, she might have a harder time finding a medication that works.
For about 20 years, many doctors have been saying that treating with antibiotics (except in extreme cases) is a bad idea. Antibiotics have the power to save lives, but taking them for months at low dosage, as for acne, is a pretty good way to grow antibiotic-resistant bugs in and on your body. These bugs are a threat to everybody, but most of all a threat to the person harboring them and his family and frienRAB. So, why are we still doing this
Because antibiotics cure pimples very well. The benefits are visible and immediate, the drawbacks are years down the line. The patient is happy, the dermatologist is paid, and life goes on.
