135 - Top Four Medications Myths: BUSTED!

In this episode, we debunk four medication myths that have persisted for decades: metronidazole and alcohol; statins and hepatotoxicity; cidal vs. static antibiotics; and "sulfa" allergies.

Key concepts

  1. Metronidazole does not interact with alcohol (ethanol) and does not cause a disulfiram-like reaction.
  2. Statins can cause transient increases in liver function tests; however, these increases are not associated with hepatotoxicity. Routine LFT monitoring is not recommended unless clinically indicated signs or symptoms of liver injury exist.
  3. The distinction of bactericidal versus bacteriostatic antibiotics is irrelevant. No evidence exists showing that having a bactericidal drug has superior efficacy to a bacteriostatic drug.
  4. A “sulfa” allergy nearly always means an allergy to Bactrim (sulfamethoxazole-trimethoprim). There are many non-antibiotic sulfonamide-containing medications that do not need to be avoided in patients with a sulfa allergy; however, patients with an allergy to any medication have an increased risk of an allergic reaction to other medication classes.
