Antibiotics Antibiotics are medications used to treat, and in some cases prevent, bacterial infections. It is essential to finish taking a prescribed course of antibiotics, even if you feel better, unless a healthcare professional tells you otherwise. If you stop taking an antibiotic part way through a course, the bacteria can become resistant to the antibiotic.

Antibiotics can destroy many of the harmless strains of bacteria that live in and on the body and in some cases can lead to the development of candida overgrowth and other illnesses, so many people take a good probiotic alongside and after a course of antibiotics to help maintain healthy gut bacteria.
