Flagyl ER, also known as metronidazole, is a commonly prescribed antibiotic medication used to treat a variety of bacterial and parasitic infections. It belongs to a class of drugs known as nitroimidazoles and works by stopping the growth of bacteria and parasites in the body.

Flagyl ER is often prescribed to treat infections such as bacterial vaginosis, trichomoniasis, and certain types of skin infections. It is also used to prevent infections after certain types of surgery. The extended-release formulation of Flagyl ER allows for a slower release of the medication into the body, which can help maintain a consistent level of the drug in the bloodstream.

As with any medication, it is important to follow your healthcare provider’s instructions when taking Flagyl ER. This includes taking the medication at the prescribed times and for the full duration of treatment, even if you start to feel better before the medication is finished. Skipping doses or stopping treatment early can lead to the development of antibiotic-resistant bacteria.

Common side effects of Flagyl ER may include nausea, vomiting, diarrhea, and a metallic taste in the mouth. If you experience any severe or persistent side effects while taking Flagyl ER, it is important to contact your healthcare provider right away.

It is also important to inform your healthcare provider of any other medications or supplements you are taking before starting Flagyl ER, as certain medications may interact with this drug. Overall, Flagyl ER is a safe and effective medication when used as directed by a healthcare provider.
