Although antibiotics are, in general, considered safe and well-tolerated, they have been associated with a wide range of adverse effects. Side-effects are many and varied, and can be very serious depending on the antibiotics used and the microbial organisms targeted. The safety profiles of newer medications may not be as well established as those that have been in use for many years. Adverse effects can range from fever and nausea to major allergic reactions including photodermatitis and anaphylaxis.
One of the more common side-effects is diarrhea, sometimes caused by the anaerobic bacterium Clostridium difficile, which results from the antibiotic's disrupting the normal balance of the intestinal flora, Such overgrowth of pathogenic bacteria may be alleviated by ingesting probiotics during a course of antibiotics
