Oral Antibiotics include erythromycin, minocycline and tetracycline. It may be up to six months before you see the full effects of these drugs, although there will probably be some difference after about six weeks. Oral antibiotics are effective in about two thirds of cases of moderate-to-severe acne, and can safely be taken for a year or more. I have taken some of these for a few months, but it did not help much. There have been people completely cured after a six month course though.
Mild-to-moderate acne can often be controlled using antibiotics such as erythromycin applied directly to the skin. These treatments come in bottles with a special sponge applicator, and should be applied over all affected areas, not just individual spots. This will not, however, have any effect on blackheads or whiteheads. This medication worked for a while, but then my face returned to its normal state. For most people it works better. This is a simple and easy to use medication; even though it stopped working after a while, it still was very convenient.
