Which precaution should be emphasized when prescribing metronidazole for trichomoniasis?

• A. It is safe for use during pregnancy
• B. Sexual contact may resume after 48hrs of treatment
• C. Sexual contacts do not require therapy
• D. Alcohol should not be used during treatment

Answer: (D)

The precaution to emphasize is avoiding alcohol during metronidazole therapy. Metronidazole can cause a disulfiram-like reaction when combined with alcohol, leading to flushing, tachycardia, nausea, vomiting, and hypotension. To prevent this, counsel the patient to abstain from all alcohol and from products containing alcohol during the course of treatment and for at least 24 to 72 hours after completing therapy, depending on local guidelines. For effective treatment of trichomoniasis, also ensure sexual partners are treated to prevent reinfection, and advise abstaining from sexual intercourse until therapy is finished.
