What is Trimo-San?

Trimo-San is used to keep healthy acid pH levels in the vagina, which helps prevent bacteria from growing and causing odor.

Trimo-San is used to lubricate and deodorize the vagina and to stop bacteria from growing. This medicine is often used by women who have a vaginal pessary (a device placed in the vagina to support pelvic organs in women with a prolapsed uterus or other pelvic issues).

Trimo-San may also be used for reasons not mentioned in this medication guide.
