Why is it important to lubricate the suppository or applicator before use?

Lubricating the suppository or applicator before use is vital primarily because it facilitates easier insertion. When a suppository or applicator is adequately lubricated, it can glide more smoothly into the body, which reduces discomfort for the person receiving the medication. This practice is particularly important in ensuring comfort and compliance, as any resistance during insertion can lead to patient distress or anxiety.

While other options may present valid considerations, they do not capture the primary purpose of lubrication. For instance, preventing medication leakage is a secondary benefit, as proper insertion technique and design of the suppository or applicator primarily govern that aspect. Similarly, the reduction of side effects and enhancement of medication effectiveness are not directly related to the act of lubrication but rather hinge on correct dosage and administration techniques. Consequently, the primary importance of lubrication lies in its role in easing the insertion process.
