Notes / example
Temperature control
Store between 36°F (2°C) and 140°F (60°C)
Extreme heat may damage medications. Aspirin can break down into vinegar and salicylic acid when exposed to heat, which may cause stomach irritation.
Avoid humidity
Store in a cool, dry place
Kitchens and bathrooms are not ideal due to humidity. Pharmacies must maintain 40%–80% relative humidity to prevent moisture buildup that can lead to spoilage or damage.
Original containers
Keep medications in their original container at home
Preserves labeling, stability, and proper identification.
Special labeling
Clearly label medications requiring special storage
“Refrigerated” should appear next to drugs requiring refrigeration. “Moisture controlled” should appear next to drugs requiring controlled humidity.
