How long can metronidazole stay good?

Metronidazole, like many medications, typically has a shelf life of about 2 to 3 years when stored properly in a cool, dry place away from light. However, it's essential to check the expiration date on the packaging and consult a pharmacist if you have any concerns about its potency after that date. Using expired medication is not recommended, as it may be less effective or potentially harmful. Always follow your healthcare provider's guidance regarding medication use.
