Drug-Supplement Interactions - 3 Hours



As the popularity of supplement use continues to escalate, health care professionals should ensure that patients are aware of the potential for Drug-Supplement Interactions. It is important for pharmacists to be able to identify  patients who are most at risk. Risk factors for poor outcomes from drug interactions include use of multiple medications and/or supplements, older age, inadequate kidney or liver function, and the use of medications with narrow therapeutic indexes. Patients with these risk factors should be targeted for interventions to prevent drug  interactions with supplements.

Upon completion of this course, pharmacists and pharmacy technicians will be able to:

  • Define the term “dietary supplement.”
  • Describe the regulatory status of dietary supplement in the United States.
  • Describe the prevalence of dietary supplement use in the United States.
  • List determinants of dietary supplement use.
  • List risk factors for drug-supplement interactions.
  • List risk factors for major drug-supplement interactions.
  • Identify potential pharmacodynamic interactions between dietary supplements and drugs.
  • Identify potential pharmacokinetic interactions between dietary supplements and drug.
  • List dietary supplements that have the potential to interact with warfarin.
  • Describe the effect of St. John’s wort on drugs metabolized by cytochrome P450 3A4.
