Vancomycin is the only other medication (antibiotic of last resort) available for the treatment of Clostridium difficile. Think of it as the Federal Reserve Bank of the United States banking system. Wow, no comfort there!
Bottom line; more and more antibiotic resistant bacteria are popping up everyday, especially in hospitals.
Doctors MUST avoid unnecessary prescribing of antibiotics. Antibiotics are often prescribed for viral illnesses that aren't helped by these drugs. Take a wait-and-see attitude with simple ailments. If you do need an antibiotic, ask your doctor to prescribe one that has a narrow range and that you take for the shortest time possible.
