What is Metronidazole 0.75% Vaginal Gel?

Metronidazole 0.75% vaginal gel is an antibiotic treatment used to treat bacterial vaginosis. It is applied inside the vagina and helps reduce the overgrowth of bacteria linked to the condition, which can improve symptoms such as unusual discharge and odour.

This product page refers to metronidazole 0.75% vaginal gel supplied on a private prescription following an online consultation.

How does Metronidazole Vaginal Gel work?

Metronidazole works by damaging the DNA of susceptible anaerobic bacteria and other microorganisms. In bacterial vaginosis, the vaginal gel helps reduce the overgrowth of bacteria linked to the condition and supports recovery of the normal vaginal environment.

What is Metronidazole 0.75% Vaginal Gel used for on this page?

On this product page, metronidazole 0.75% vaginal gel is used specifically for:
