Tetracycline antibiotics are often used to treat acne, specifically minocycline, doxycycline, and tetracycline. Solodyn is also used. Since being on this board I have also heard of others such as Bactrim being prescribed. The dosing is obviously up to the physician that prescribes them, I have been on antibiotics that I have taken once a day and I have been on some that I have taken twice a day. It just depends on the dosage your doctor feels you need. Some people have better results with antibiotics while others do well with topicals and still others don't respond with either, just depends on the person and their skin. In my personal experience, antibiotics have helped with more severe outbreaks. Best of luck to you!

stay away from antibiotics!
