Metrogyl 400 Tablet
Description
Metrogyl 400 Tablet is a prescription medicine used to treat diarrhoea, dysentery, and infections caused by bacteria, parasites, and other harmful microorganisms. It contains metronidazole, an antibiotic that works by stopping the growth of infection-causing organisms and preventing them from spreading in the body.
You should take Metrogyl 400 Tablet exactly as prescribed by your doctor and for the full duration of treatment. It is best taken with meals to reduce the chances of stomach upset. Skipping doses or stopping treatment too early may reduce its effectiveness and increase the risk of the infection returning.
While using Metrogyl 400 Tablet, some people may experience side effects such as nausea, metallic taste, or stomach discomfort. These are usually mild and temporary. However, if you experience persistent or severe side effects, consult your doctor immediately. Always follow your doctor’s advice for the safest and most effective use.
This medicine is not recommended for use during pregnancy and breastfeeding, unless specifically advised to do so by a doctor. Elderly patients should use Metrogyl 400 Tablet with caution, as they may be more sensitive to its effects. Before starting treatment, it is essential to inform your doctor about your complete medical history and all other medications or supplements you are taking to prevent potential drug interactions.
Other medicines, such as Metrogyl 200 tablets, Metron 400, and Metropar 400, also contain metronidazole as the active ingredient and may be prescribed for similar infections. Always use the brand and dose recommended by your doctor for the best results.
