This goes back to this.
Metronidazole is often known in the US by the brand name Flagyl. It is an antibiotic that is often prescribed for a number of anerobic infections and sexually transmitted diseases. It has what is called a disulfram-like reaction. Often when you pick up medicine at the pharmacy you may be counseled to avoid taking alcohol with a medication. In some cases this can be due to the fact that combining alcohol with a given medication can be dangerous or even lethal. Taking alcohol with metronidazole won’t kill you, it will however make you wish that you were dead. You’ve been warned.
