Prescription drugs interact with certain foods, supplements, and herbs with detrimental consequences. Instead of a positive outcome, food-drug interactions can negatively affect the intended action of a medication regimen by decreasing its effectiveness and leading to increased morbidity, extended treatment duration, or hospitalization. Food-drug interactions can also lessen quality of life if the medication is not controlling symptoms when the effectiveness of the medication is compromised by food. In certain populations, including older adults and those with compromised organ systems, the effects of food-drug interactions are more significant. The number of people taking prescription drugs increases every year, and healthcare providers need to be well versed in the potential interactions of prescription drugs with food, food substances, and dietary supplements to educate patients appropriately and help lessen potentially adverse effects.


The goal of this continuing education program is to educate healthcare professionals about the adverse outcomes and change in effectiveness of prescription drugs caused by the intake of certain foods, food substances, and dietary supplements. After studying the information presented here, you will be able to:
  • Identify at least five factors affecting the therapeutic outcome of drug therapy
  • Explain the dietary monitoring and modifications needed for the medications discussed
  • Identify potential grapefruit-drug interactions and the potential effects on the body
  • Identify five common herbal preparations or supplements that interfere with the pharmacokinetics of certain drugs
