Basic Pharmacology & Drug Nutrient Interactions

Presenter: Debbie Grayson

The aim of this one-day workshop is to understand more about which supplements are safe to use with prescribed medication and how drugs interact with the body. This course is recognised by the British Association for Applied Nutrition and Nutritional Therapy (BANT) and provides 7 CPD hours towards therapists’ annual accreditation and certification is provided.

By the end of the session, practitioners will:

  • Understand how drugs are distributed around the body (pharmacokinetics);
  • Understand how drugs exert their effect (pharmacodynamics);
  • Know which resources are best for finding this information;
  • Know which resources are available for checking drug/nutrient interactions;
  • Understand how to assess the relevance of an interaction;
  • Know which actions to take when using supplements that interact with medication.


I have attended Debbie’s drug interaction course and it was a real revelation. As a health practitioner you will come across clients who are taking different medications on a regular basis. How to proceed here can be really tricky and you need to know exactly what you can safely do to help them and where you get into dangerous territory. This course has really opened my eyes and now I know exactly where to find the crucial information and what to do with it. I am so glad I went and I highly recommend this course to anybody who is working in the health industry.

Debbie Grayson, an experienced pharmacist and nutritional therapist, will give practitioners an understanding of how drugs interact with the body and how commonly used nutritional supplements and foods can affect this.

The course objective is to give practitioners practical examples of interactions between common pharmaceutical drugs and supplements. Consequences of certain drug and nutrient interactions can be life threatening, for example Warfarin and high dose fish oils could result in a client having a catastrophic bleed.

Attendees will gain confidence in making safe decisions about when supplements can be used and how to proceed if there is a potential interaction problem.
