Final answer:
The PDR number, which stands for Physicians' Desk Reference, is not typically found on medication labels. Medication labels usually feature the supply dosage, a control number, and label alerts but not PDR numbers.
Step-by-step explanation:
The item on a medication label that is not typically found is the PDR number. A medication label will usually include the supply dosage, which indicates how much and how often the medication should be taken, and the control number, which is a unique identifier for that particular batch of medication. Also, a label alert may be present to provide critical information about the medication such as potential side effects or interactions with other drugs. However, the PDR number, which stands for the Physicians' Desk Reference number, is not commonly found on medication labels as this is a reference book containing information about drugs.
