Flagyl (brand) is metronizazole (generic) and it does nothing for most people (to help with alcohol consumption).. especially if one is of an addictive nature. But because some people do react to alcohol when prescribed metronidazole, it has to be noted as a side effect.
Basic alcohol intolerance is a deficiency of the enzyme Aldehyde Dehydrogenase (ALDH) that is needed to metabolize the alcohol into acetic acid (vinegar). Alcohol unless broken down is toxic to the body. An immediate immune response is triggered and symptoms typical to an allergy occur trying to get rid of the toxins. The adverse reaction to the ingestion of alcohol by taking metronidazole is caused by inhibiting the effect of ALDH.
Metronidazole is an antibiotic used to treat anaerobic bacteria and protozoa, mainly in the vagina, stomach, skin, joints, and respiratory tract.
It is also very successfully used in veterinary medicine for GI disturbances (mainly feline, such as IBD), and has been known to successfully treat canine tetanus.
