The pharmacist as self-care advisor.

A patient's decision to purchase a nonprescription product is driven by several factors, including the manufacturer's advertising claims, the advice of friends or relatives, and past experience with the product. Pharmacists must be well-versed in product- and patient-related factors governing the appropriate use of nonprescription products in order to make appropriate recommendations to their patients and to direct them to a physician or other health care professional when necessary.
