What is the 5 percent rule in pharmacy compounding?

The 5 percent rule in pharmacy compounding refers to the guideline that allows pharmacists to compound a medication for a specific patient based on a prescription, provided that no more than 5 percent of the total quantity compounded is distributed to other patients or healthcare providers. This rule is intended to ensure that compounded medications are primarily prepared for individual patients rather than for commercial distribution. It helps maintain the integrity and safety of compounded medications while allowing pharmacists some flexibility in their practice.
