Which of the following medical supplies should be refrigerated?

Aureomycin, also known as chloramphenicol, is an antibiotic that is sensitive to heat and light, which can compromise its efficacy. Refrigeration helps maintain its stability and effectiveness, ensuring that it remains potent for use as prescribed. Proper storage at cooler temperatures is essential to prevent degradation, which can potentially lead to ineffective treatment in patients.

Other choices, such as Vaseline jelly, Paregoric, and Hydrogen Peroxide, do not require refrigeration. Vaseline jelly is a petroleum product that remains stable at room temperature. Paregoric is a medication that can be stored at room temperature without losing its integrity. Similarly, Hydrogen Peroxide can also be kept at room temperature as long as it is stored in a dark container to prevent light exposure, which can degrade its properties.
