Metronidazole vaginal gel is primarily used for the treatment of bacterial vaginosis, a common vaginal infection caused by an imbalance and overgrowth of certain bacteria in the vagina[1][2][5]. It is an antimicrobial agent that works by stopping the growth of bacteria responsible for the infection[1].
Bacterial vaginosis (BV) usually presents with symptoms such as abnormal vaginal discharge and a fishy odor, though some women may be asymptomatic[5]. Metronidazole vaginal gel is typically administered intravaginally using a special applicator once daily at bedtime, or sometimes twice a day, for 5 consecutive days, depending on your doctor’s instructions[1][2][4]. The gel is not intended for use during menstruation and sexual intercourse should be avoided while using the medicine[2].
Metronidazole vaginal gel may also have an indication for treating trichomoniasis (a vaginal infection caused by Trichomonas vaginalis) in certain cases, but this is less common and not the primary approved use for the gel formulation[3].
