Interactions: Learning outcomes

Last updated: Monday, November 15, 2021

After completing this tutorial, you will be able to:
  • Describe common mechanisms by which drugs interact.
  • Adopt a practical approach to identifying, managing, and monitoring interactions.
  • Talk to patients about drug interactions.

You can download a PDF of the whole tutorial (without interactive elements such as the Learning exercises) and a one-page summary of key points.

You should allow 90 minutes to complete this tutorial, including the Learning exercises.


This tutorial is aimed at hospital trainee pharmacists, and will help you achieve GPhC learning outcomes such as these:
  • LO 5 Proactively support people to make safe and effective use of their medicines and devices
  • LO 12 Take an all-inclusive approach to ensure the most appropriate course of action based on clinical, legal and professional considerations
  • LO 16 Apply professional judgement in all circumstances, taking legal and ethical reasoning into account
  • LO 27 Take responsibility for the legal, safe and efficient supply, [prescribing] and administration of medicines
  • LO 29 Apply the principles of clinical therapeutics, pharmacology and genomics to make effective use of medicines for people [including in their prescribing practice]
  • LO 30  Appraise the evidence base and apply clinical reasoning and professional judgement to make safe and logical decisions which minimise risk and optimise outcomes for the person
  • LO 34 Apply the principles of effective monitoring and management to improve health outcomes
  • LO 48 Actively take part in the management of risks and consider the impacts on people

If you are a foundation pharmacist, this tutorial may help you meet competencies from the RPS framework including:
  • 1.4  Selection of the medicine (medicine-medicine, medicine-patient, medicine-disease interactions)
  • 1.7  Monitoring medicine therapy
  • 3.2  Knowledge (drug interactions)
  • 3.3  Analysing information
  • 3.4  Providing information

Continuing professional development

Finally, here are some CPD activities you could consider:

★  Have you ever found it difficult to talk to a doctor about an interaction? If so, reflect on why this was the case. How might you do it better next time?
★  Write up an account of an interaction that you managed in practice and present it as a case study at your work journal club, or as part of your diploma. Highlight how your intervention had an impact on patient care.
★  Sit down with a pharmacist colleague to discuss an interaction that you prevented or managed on your ward. Did your colleague agree with your approach? What did you learn from sharing your experiences?
★  Are there any aspects of this topic that make you feel uncertain, or where you know you need a better understanding? If so, then find a relevant review to read, and write up what you learn as a CPD exercise.
