Overview
Pharmaniaga Metronidazole 200mg Tablet contains metronidazole 200mg, an antibiotic and antiprotozoal medicine used to treat infections caused by certain bacteria (particularly anaerobic bacteria) and protozoal parasites. It is commonly used for dental, gynaecological, gastrointestinal, and skin infections, as well as certain protozoal infections.
Metronidazole is activated inside susceptible bacterial and protozoal cells, where it damages the organism’s DNA, preventing it from replicating and leading to its death, while human cells are not affected in the same way.
How it Works
Once inside a susceptible bacterial or protozoal cell, metronidazole is chemically reduced to an active form that binds to and damages the organism’s DNA. This disrupts DNA synthesis and structure, causing the bacteria or protozoa to die, which clears the infection.
Directions for Use
Take Pharmaniaga Metronidazole 200mg Tablet with food or a glass of milk to reduce stomach upset, at evenly spaced times as directed by your doctor. It is important to avoid alcohol during treatment and for at least 48 hours after your last dose, as combining alcohol with metronidazole can cause a disulfiram-like reaction with nausea, flushing, and a rapid heartbeat.
Dosage
The dose and duration of Pharmaniaga Metronidazole 200mg Tablet depend on the type of infection being treated, but a common regimen is 400-500mg two or three times daily for 5-7 days, or a different schedule for protozoal infections. Always complete the full course exactly as prescribed by your doctor.
