USES: Penicillins are antibiotics used to treat a wide variety of bacterial infections.
HOW TO USE: This medication must be used as directed by your doctor. Clean area before administering. Antibiotics work best when the amount of medicine in your body is kept at a constant level.

This medication may rarely cause a severe intestinal condition (pseudomembranous colitis) due to a resistant bacteria. This condition may occur while receiving therapy or even weeks after treatment has stopped.
