A prescription drug with no storage requirements is best stored at:

• A. In a freezer
• B. At controlled room temperature
• C. In a refrigerator
• D. In direct sunlight

Answer: (B)

Storing a drug with no special storage needs at controlled room temperature keeps it in a stable, practical environment without exposing it to extremes that could affect potency. Freezing is unnecessarily cold for most medicines and can cause physical or chemical instability; refrigeration is also more cool than needed for these drugs and isn’t required unless specified. Direct sunlight can trigger degradation through light exposure, reducing effectiveness. Controlled room temperature—roughly 68–77°F (20–25°C) with typical allowable variation—provides a safe, stable setting for these medicines, making it the best choice.
