What can stop metronidazole from working?
The number 1 cause of ineffectiveness for any antibiotic is: overuse. Your body can become immune to its effects if you’re constantly being treated with the same medication (overexposure). Drinking alcohol while taking Metronidazole can also decrease its effectiveness and other medications can interact. Usually your healthcare provider will check to see if there are any possible interactions if you’re taking any other prescriptions before prescribing.
