Metronidazole is a common antibiotic used to treat various bacterial and protozoal infections. While it is generally safe and effective when used as prescribed, prolonged use of metronidazole can lead to certain side effects.
One of the potential side effects of prolonged use of metronidazole is a disruption in the balance of beneficial bacteria in the gut, which can result in gastrointestinal issues such as diarrhea, nausea, and abdominal pain. In some cases, long-term use of metronidazole can also lead to the development of antibiotic-resistant bacteria.
It’s important to always follow your healthcare provider’s instructions when taking metronidazole and to not use it for longer than prescribed. If you experience any unusual symptoms or side effects while taking this medication, be sure to consult your healthcare provider immediately.
