There is a close relationship between ceftriaxone, which is a type of antibiotic, and Candida vaginitis, which occurs when patients use large amounts of antibiotics over a long period of time, causing a decrease in the body’s immune function and a dysbiosis in the vagina. Patients are required to apply antibiotics according to their condition in their daily life and not to use antibiotics indiscriminately to avoid causing Candida vaginitis.
