What is the role of lubricant when inserting a suppository?

The role of lubricant when inserting a suppository is primarily to aid in slickness for easier insertion. Using a lubricant reduces friction, which can make the process more comfortable for the individual receiving the suppository. Inserting a suppository can sometimes cause discomfort; thus, lubrication contributes to a smoother experience and decreases the chances of tearing or irritation to the rectal or vaginal mucosa during insertion.

While lubrication can enhance the ease of administration, its primary purpose is not to enhance drug absorption in the body or to cleanse the area. Therefore, a lubricant is not merely optional; its use is considered a best practice to ensure a comfortable and effective administration of the suppository.
