Correct answer: C — Avoid alcohol during treatment and for 48 hours after finishing

Metronidazole can cause a disulfiram-like reaction with alcohol, including flushing, nausea, vomiting and palpitations. Alcohol should be avoided during treatment and for a short period after completion. The patient should continue the antibiotic course as prescribed unless advised otherwise.
