YOU SHOULDN'T MIX ANTIBIOTICS AND ALCOHOL
How wrong is this? Totally, with the exception of the antibiotic metronidazole.
What are the facts? Any interaction of alcohol with virtually all antibiotics is nonexistent, or so small as to be irrelevant. Metronidazole, an antibiotic used for a variety of infections, is the exception to this rule. When mixed with even small amounts of booze, it causes vomiting.
Any related myths? That you should always finish your course of antibiotics. It usually makes little difference.
