Medications not to be refrigerated.

Abstract

A survey of selected drug labelers was conducted to generate a list of drug products that should not be refrigerated. Letters asking for information on products adversely affected by refrigeration were mailed to 109 drug product labelers. A second letter was sent to nonresponders and to labelers providing incomplete information. Responses were received from 97 labelers, 43 of whom stated that none of their products would be harmed by refrigeration. Eleven labelers were unable to provide conclusive data or a list of specific drug products that refrigeration would harm. Lists of drug products not to be refrigerated were provided by 43 labelers, some including explanations of the adverse effects of refrigeration. Pharmacists may find the survey's data useful in their patient education activities.
