A six (6)-day treatment is recommended to help restore normal pH levels and normal vaginal flora. If, after six (6) days, you are still experiencing symptoms or if your symptoms worsen while using Prevegyne®, please consult a healthcare professional.

How does Prevegyne® work?

Prevegyne®’s special vaginal formulation slowly releases a moderate quantity of vitamin C over several hours. This reduces the risk of irritation of the vaginal walls that can occur with high concentrations of vitamin C.

Prevegyne® helps restore vaginal flora by decreasing intravaginal pH (≤ 4). A pH below 4 favours good bacteria like lactobacilli (major constituents of the normal vaginal flora), capable of growing even at pH values ≤ 4. Decreased vaginal pH also limits the survival of pathogenic bacteria that negatively affect vaginal environment.

Dosing form

Prevegyne® is supplied in the form of controlled-release vaginal tablets. Each tablet contains 250 mg of ascorbic acid (vitamin C).

Each box contains 6 tablets, 1 plastic vaginal applicator and the consumer information leaflet.
