Prescription drugs are an important intervention to decrease the complications of medical conditions, but interactions between prescription drugs and certain foods, supplements and herbs can result in detrimental consequences. Instead of a positive outcome, food-drug interactions can affect the intended action of a medication regimen negatively by decreasing its effectiveness and leading to increased morbidity, extended treatment duration or hospitalization. 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 prescription drug-food interaction continuing education module is to inform dietitians, dietary managers, fitness professionals, health educators and occupational therapists regarding the adverse effects and effectiveness of prescription drugs caused by the intake of certain food, food substances and dietary supplements. After reading this module, the participant will be able to:
  • Identify at least five factors affecting the therapeutic outcome of drug therapy
  • Identify potential grapefruit-drug interactions and the potential effect on the body
  • Discuss dietary monitoring and modifications needed for medications discussed
  • Identify five common herbal preparations or supplements that interfere with the pharmacokinetics of certain drugs
  • Identify one drug classification that herbal preparations or supplements affect
