The issue of labeling is still unresolved. It is considered that the use of the term “controlled room temperature” would be meaningless for certain areas of trade that are not aware of the USP. The more extensive wording of USP, Controlled Room Temperature,is too verbose for most labels and incomprehensible to many areas of the trade. Many companies have retained the old USP definition (15°C–30°C) on their labeling until this is resolved by the FDA.
