Herbal-Drug Interactions Important in Dentistry - L0790


About Course #L0790

Release Date: November 2, 2016

Expiration Date: November 1, 2019

In the United States and Europe, over-the-counter natural herb products constitute a rapidly growing market, having joined prescription and over-the-counter medicines that were originally derived from herbs. Interest in herbal medicine has been facilitated by multiple factors, including the perception that pharmaceutical medications are expensive, overprescribed, and often dangerous. Alternatively, herbal medicines are often perceived as being "natural," and therefore safe.

This basic-level course describes the prevalence and risk for interactions involving herbal medicines and lists the herbal medications and drugs of greatest concern to dental professionals. A stoplight approach to risk assessment is discussed and a general strategy to avoid the most common herbal-drug interactions is suggested. Critical patient populations (including women who are pregnant or breast feeding) are emphasized and specific herbal-drug interactions that can lead to increased bleeding, decreased blood glucose levels, and sedation changes are discussed.
