Standard treatment regimens for bacterial vaginosis depend on nitroimidazole agents. When a patient has a documented allergy or intolerance to metronidazole and/or tinidazole, those agents cannot be used — and a specific alternative approach is required.
This protocol addresses bacterial vaginosis in patients with allergy or intolerance to metronidazole and/or allergy or intolerance to tinidazole. Because the most commonly prescribed first-line oral agents are contraindicated or not tolerated, treatment must follow a different route.
When oral nitroimidazoles are not an option, the recommended approach involves an intravaginal antimicrobial therapy. The specific preferred agent, any alternatives, and the complete administration details are set out in the full structured protocol.
The aim of treatment is relief of vaginal symptoms and signs of infection.
