Which statement about metronidazole is accurate for client education?

Metronidazole is an antibiotic and antiprotozoal medication commonly used to treat various infections, including those caused by anaerobic bacteria and certain parasites. It is particularly important to inform clients that metronidazole should not be taken with alcohol due to the risk of a disulfiram-like reaction. This reaction can cause unpleasant symptoms such as flushing, nausea, vomiting, and palpitations, which can lead to a severe and uncomfortable experience.

This interaction occurs because metronidazole inhibits the metabolism of alcohol, leading to the accumulation of acetaldehyde, a byproduct that is typically processed by the body. Advising clients to avoid alcohol while taking metronidazole ensures their safety and comfort during the treatment period.

In contrast, while metronidazole is a useful medication, it is not recommended for use during pregnancy due to potential risks to the developing fetus. It is also not indicated for clients with blood disorders without careful consideration of the risks versus benefits. Lastly, metronidazole is specifically effective against certain bacterial and parasitic infections, but it does not address viral infections, which require different antiviral medications for effective treatment.
