This article reviews preclinical and clinical studies on the repurposed use of disulfiram (Antabuse) as an antimicrobial agent. Preclinical research covered on the alcohol sobriety aid include uses as an anti-MRSA agent, a carbapenamase inhibitor, antifungal drug for candidiasis, and a treatment for parasitic diseases due to protozoa (e.g., giardiasis, leishmaniasis, malaria) and helminthes (e.g., schistosomiasis, trichuriasis). Past, current, and pending clinical studies on disulfiram as a post-Lyme disease syndrome (PTLDS) therapy, an HIV latency reversal agent, and an intervention for COVID-19 infections are also reviewed.

This case report describes a complex trauma patient who developed hyperkalemia secondary to heparin. Heparin is a commonly used drug in trauma patients. Physicians need to be aware of this potentially harmful adverse reaction in these high-risk patients.
