What is the primary use of pessaries?

Pessaries are primarily used for vaginal administration. They are medical devices that are inserted into the vagina and can serve various purposes, such as delivering medication, providing support for pelvic organ prolapse, or managing conditions like urinary incontinence. The design and function of a pessary allow for localized treatment directly at the site of action, which can enhance the effectiveness of the medication while minimizing systemic side effects that might occur with other forms of administration.

In contrast, oral treatment involves medications taken by mouth, intravenous delivery requires insertion into a vein, and topical application pertains to medication applied to the skin's surface. Each of these methods differs fundamentally from the use of pessaries, which are uniquely tailored for vaginal use.
