Can pregnant women use concentrated metronidazole mouthwash?

Patient's question:

No

Doctor's answer:

Hello, pregnant women should not use concentrated metronidazole mouthwash. The liquid can still be absorbed by the human body, which may affect the child. Concentrated metronidazole mouthwash is primarily used as an adjunctive treatment for oral diseases such as gingivitis, pericoronitis, and periodontitis caused by anaerobic bacterial infections.
