Metronidazole tablets are commonly prescribed antibiotics used to treat a wide range of bacterial and parasitic infections. They are often recommended for conditions such as dental infections, skin infections, stomach infections, bacterial vaginosis, and certain intestinal infections. The medicine works by stopping the growth of harmful bacteria and parasites in the body, helping patients recover faster and reduce infection-related symptoms. Metronidazole 400 mg tablets should be taken exactly as directed by a healthcare professional, usually after food to minimize stomach discomfort. Patients are advised to avoid alcohol while using this medication, as it may cause unwanted side effects like nausea or dizziness.
