Brief Answer: Metronidazole Detailed Answer: Hello, The metalic taste is due to metronidazole. It will go off in a weeks after stopping metronidazole. All other symptoms are non specific and may not be related to Pylera. So my advise is not to stop pylera and continue the full course of treatment prescribed by the doctor. It is usually prescribed for two weeks. Regards.
