Which of the following is NOT typically included on an OTC product label?

An over-the-counter (OTC) product label typically includes essential information to ensure the safe and effective use of the medication. One of the crucial aspects required by regulations is the adequate directions for use, which provide instructions on how to properly use the medication. Additionally, the label must state the net quantity of contents so consumers know how much product they are purchasing. Cautions and warnings of use inform consumers of potential risks or contraindications associated with the product.

While OTC product labels do include information regarding side effects, this information is often described in broader terms, such as "may cause drowsiness" or "common side effects." It is important to note that the primary focus of OTC labeling is on directions for safe usage rather than an exhaustive list of side effects. Therefore, while side effects might be mentioned, they are not typically presented on the label as prominently or in detail compared to the other components. This distinction helps clarify why side effects, while important, may not always be detailed in the most accessible way compared to other label elements such as directions, warnings, and net contents.
