Personalized Management of Hydroxyquinoline Hypersensitivity in Pessary Care: A Case-Based Approach to Tailored...

Background and Clinical Significance: Many women use pessaries to manage their symptoms of pelvic organ prolapse. Hydroxyquinoline is the active ingredient in gels and ointments that are often used to lubricate a pessary prior to vaginal insertion and to provide antimicrobial effects while the pessary is in situ. Case Presentation: A 74-year-old woman with multiple medication allergies develops vulvovaginal erythema and pruritus after increasing vaginal Trimo-San application frequency for pessary care and maintenance. These symptoms are deemed to be consistent with an allergic reaction to hydroxyquinoline, the active ingredient in Trimo-San. Conclusions: This report highlights the importance of personalized treatment in pessary management. It also demonstrates how personalized medicine can optimize outcomes and improve treatment adherence among individuals with complex medical histories.
