Dr. Wolff's V-san Lactic Acid Pessaries help prevent vaginal infections by maintaining and restoring natural vaginal pH levels. They are quick and effective, acidifying the vaginal environment and balancing it to the natural pH level after menstruation, sexual intercourse, or sweating. These pessaries contribute to daily vaginal health and provide natural protection against infections. They can be safely used during pregnancy and breastfeeding and are suitable for long-term use. To use, insert one pessary as deep as possible into the vagina in the evening before bed. Moisten the pessary under running water before insertion for easier application.
