What is the recommended storage condition for Aztreonam (Cayston)?

  1. Room temperature

  2. Refrigerated

  3. Freezer

  4. Heated environment

The correct answer is: Refrigerated

Aztreonam (Cayston) should be stored in a refrigerated condition. This is because it is a liquid medication that contains delicate compounds and could easily degrade if exposed to extreme temperatures. Keeping it refrigerated helps to maintain its stability and effectiveness. Room temperature (option A) may vary and could sometimes become too warm for storage, while freezing (option C) could cause the liquid to expand and potentially damage the container. A heated environment (option D) could also cause the medication to deteriorate. Therefore, option B is the recommended and safest storage condition for Aztreonam (Cayston).
