Correct answer: E — Avoid alcohol during treatment and for a short period after completing it

Patients are commonly advised to avoid alcohol during metronidazole treatment and for a period after finishing because of a possible disulfiram-like reaction and worsening adverse effects. Skipping doses risks treatment failure. Doubling doses increases adverse-effect risk. Counselling should also cover completing the course and seeking advice if symptoms persist.
