Correct answer: C — Avoid alcohol during treatment and for a short period after finishing

Alcohol should be avoided with metronidazole because unpleasant reactions such as flushing, nausea, and vomiting can occur. The patient should continue the antibiotic as prescribed and avoid deliberately missing doses. Metallic taste and gastrointestinal upset are recognised adverse effects.
