What is hydroxyquinoline?

Hydroxyquinoline is used to maintain healthy acid pH levels in the vagina, to prevent bacteria from growing and causing odor.

Hydroxyquinoline is used to lubricate and deodorize the vagina, and to prevent the growth of bacteria. Hydroxyquinoline is often used in women who wear a vaginal pessary (a device inserted into the vagina to support pelvic organs in women with prolapsed uterus or other pelvic problems).

Hydroxyquinoline may also be used for purposes not listed in this medication guide.
