Drug-Supplement Interactions


This CE activity was originally published in The Rx Consultant.  If you received credit for it previously, you cannot receive credit for it again.
 
The use of complementary and alternative therapies continues to grow in the United States. The use of dietary supplements (eg, vitamins, minerals, herbal or botanical products) represents the largest segment of these therapies. Surveys show that from 1988-1994, over 40% of the U.S. adult population took supplements. From 2003-2006, about 50% of U.S. adults were found to take supplements.

The prevalence of dietary supplement use may be even higher in certain populations. About 70% of adults over 71 years of age reported using dietary supplements from 2003-2006. In cancer patients, the use of alternative therapies may be as high as 83%, and the use of herbal supplements may be as high as 63%.

Of concern, most supplement users (67%) do not inform their healthcare providers about their supplement use. Among those taking a prescription drug and 1 or more dietary supplements, nearly 70% do not tell their providers about supplement use. In people with chronic medical conditions, about 50% do not disclose dietary supplement usage to a healthcare provider.


The widespread use of dietary supplements, especially among older people, patients with chronic conditions, and those taking prescription medications, suggests that the potential for drug-supplement interactions is high.
