What temperature should a pharmacy refrigerator maintain according to USP standards?

The correct temperature range for a pharmacy refrigerator, as specified by USP standards, is 36 to 46 degrees Fahrenheit. This range is essential for preserving the stability and efficacy of various medications, particularly those that are temperature-sensitive, such as vaccines and certain biologics. Maintaining the temperature within this specified range helps ensure that these medications do not degrade or lose potency due to improper storage conditions.

Other options fall outside the recommended range, which could jeopardize medication quality and safety. For example, temperatures above 46 degrees Fahrenheit could cause degradation of medicines, while temperatures below 36 degrees could lead to freezing of certain products, affecting their integrity. Therefore, adhering to the USP standards of 36 to 46 degrees F is crucial for effective pharmaceutical care and patient safety.
