What is the correct room temperature range for controlled drugs?

• A. 0-5 degrees C
• B. 15-25 degrees C
• C. 8-25 degrees C
• D. 6-20 degrees C

Answer: (C)

Storing controlled drugs in the right indoor temperature helps maintain their potency and stability. The defined room temperature range of eight to twenty-five degrees Celsius gives a practical buffer for most veterinary settings, ensuring drugs aren’t exposed to freezing or excessive heat that could degrade them. It matches common guidance for medicines stored at “room temperature,” while avoiding too-cold fridge storage (0–5 °C) and staying broad enough to cover typical clinic climates. A range that starts higher or ends lower would miss out on premises where temperatures dip to around eight or rise toward twenty-five, which is why eight to twenty-five degrees is the preferred standard.
