Metronidazole 400 mg is a prescription-only antibiotic used to treat Bacterial Vaginosis (BV), a common condition caused by an imbalance in the natural bacteria found in the vagina. BV can lead to symptoms like unusual vaginal discharge, a fishy odour, irritation, and discomfort. Metronidazole works internally to clear the infection and restore healthy balance — often within just a few days of starting treatment.
How It Works
Metronidazole belongs to a group of antibiotics that target anaerobic bacteria — the type that thrive in low-oxygen environments like the vagina during BV. The medicine disrupts these bacteria’s ability to grow and reproduce by damaging their DNA. As a result, harmful bacteria are eliminated while allowing beneficial bacteria to return, helping restore a healthy vaginal environment.
The 400 mg tablet is typically taken twice daily for five to seven days. Because the medication is absorbed into your system, it treats the infection throughout the body, not just at the surface. This approach ensures a more complete and lasting result.
Why Choose Metronidazole
Metronidazole is the first-line treatment for BV and is trusted by GPs and sexual health clinics across the UK. It offers a convenient oral alternative to vaginal gels or creams, especially for people who prefer tablets. With proven effectiveness, rapid results, and broad usage history, it’s a reliable solution for many women.
The treatment is discreet, easy to follow, and generally well tolerated. When taken as directed, most people experience full relief without needing additional medications.
Important Note
Avoid alcohol during the course and for 48 hours after the last dose — combining the two can lead to severe nausea, vomiting, and flushing. Always finish the full course even if symptoms improve early, to avoid reinfection or resistance.
