Order delivery days often come with a sense of dread for pharmacy staff. Totes of new inventory, which are coming into a pharmacy that is already cramped, must be unpacked and put away so prescriptions can be filled. Not only do pharmacy staff not have the time to do so, but there is often a lack of space in buildings that were never updated to be able to store the thousands of new drugs that have become available in recent decades.
There is much more to safe medication storage, however, than just putting it away. Many factors must be considered, including environment, climate, security, rotation, segregation, and documentation at every step of the way.
Environment
The environment in which medications are stored should be large enough to allow for orderly storage, including proper signage, rotation, and cleaning.1 Sufficient lighting and ventilation are also important parts of medication storage.1 Good lighting is required for choosing the correct medication. Space for ventilation is needed to ensure consistency of temperature while in storage, and this also provides room for cleaning.
Of course, cleanliness is required to keep medications from becoming contaminated. Medications should be kept off the floor, and shelves should be dusted regularly.1 The pharmacy should always be free of dust, dirt, vermin, and insects. If any vermin or insects are found, management should be advised to have an exterminator service the premises.

Climate
All medications have storage requirements, such as specific temperature and humidity guidelines, protection from sunlight, and other considerations. Storage requirements help ensure that medications maintain their potency and help reduce the risk of harm to patients. Medication storage requirements may be found on the medication’s label or from a third-party resource.2
Manufacturers must specify the required storage temperature of their products. This may be generalized to room temperature, cool temperature, refrigerated, or frozen. The Table3 provides a guide for temperature management.
The CDC recommends best practices for storing refrigerated medications, including checking and recording the minimum and maximum temperature daily or, if the thermometer does not record minimum and maximum temperatures, checking and recording the temperature twice daily. The CDC also recommends that staff note their initials when documenting temperatures.
Finally, part of these best practices includes acting upon cases of temperature excursions.4 In case of temperature excursions, call the manufacturer of the medication and tell them the length of time the drug has been out of range temperature. They will advise as to how long the product can stay out of range temperature and whether the product can still be used.4
