Question 44

The oral formulation of Metronidazole is contraindicated with alcohol.

Metronidazole should not be taken with alcohol due to the risk of a disulfiram-like reaction, which can cause severe side effects including flushing, nausea, and vomiting.

A) Metronidazole

This option is correct because Metronidazole is well-known for its interaction with alcohol. Patients are advised to avoid alcohol during treatment and for at least 48 hours after completing the medication, as the combination can lead to unpleasant and potentially dangerous effects.

B) Vancomycin

Vancomycin does not have a known contraindication with alcohol. While it is important to monitor kidney function during treatment, there is no evidence suggesting that alcohol consumption affects the efficacy or safety of Vancomycin.

C) Clotrimazole

Clotrimazole is an antifungal medication that does not have any significant interactions with alcohol. Therefore, it is not contraindicated and can be used without concern regarding alcohol consumption.

D) Azithromycin

Azithromycin does not have any documented contraindications with alcohol. While patients should always be cautious with alcohol use during any medication regimen, Azithromycin is not specifically affected by alcohol.

Conclusion

Metronidazole is the only drug listed that is contraindicated with alcohol due to the serious risk of disulfiram-like reactions. The other options—Vancomycin, Clotrimazole, and Azithromycin—do not present similar risks, making them safe to use alongside alcohol. Thus, understanding specific drug interactions is crucial for safe medication practices.
