Metronidazole Antibiotic Pharmacology for Nursing NCLEX

This content covers the pharmacology of metronidazole, an antimicrobial agent within nursing pharmacology, whose primary indications are treatment of Clostridioides difficile (C. diff) infection and sexually transmitted trichomoniasis. The core clinical principle taught is a disulfiram-like drug-alcohol interaction requiring alcohol avoidance during and after treatment, alongside distinguishing benign, expected side effects (dark/discolored urine, metallic taste) from a dangerous adverse reaction (Stevens-Johnson syndrome, presenting as rash and skin peeling) that must be reported immediately.
