Abstract

The purpose of this study was to explore the benefit of high-dose intravaginal metronidazole as a maintenance therapy in reducing recurrence rates of bacterial vaginosis (BV).

Eighteen women with a history of recurrent BV and symptomatic BV were treated with metronidazole 750 mg suppository intravaginally daily for 7 days. Those in remission by Amsel criteria received metronidazole 750 mg twice weekly for 3 months with further follow-up for 3 months. High-dose metronidazole intravaginally was associated with rare clinical recurrence during the period of use. After cessation of suppression therapy, recurrence was high.
