RT Book, Section A1 McQueen, Cydney E. A2 Sutton, S. Scott SR Print(0) ID 1179737069 T1 Herbal and Nonherbal Dietary Supplements T2 McGraw Hill’s NAPLEX® Review Guide, 4e YR 2020 FD 2020 PB McGraw-Hill Education PP New York, NY SN 9781264258062 LK accesspharmacy.mhmedical.com/content.aspx?aid=1179737069 RD 2024/04/20 AB Many patients regularly use or occasionally try supplements, either along with prescription and over the counter (OTC) therapies, or in place of some therapies. Because pharmacists must educate and advise patients on drug therapies, it is essential to have a basic understanding of dietary supplements (DS) in order to assist in avoiding harm, whether from drug interactions (Table 74-1), use of a contraindicated supplement, or a poor quality product. Pharmacists do not control access to these products, but can provide essential advice and recommendations.
