In this scenario, a GP trainee seeks advice about a patient who is experiencing side effects whilst taking naproxen and is now reluctant to continue with their medication. The pharmacist will take a history, offer solutions, and answer any questions the GP trainee has. 

Please ensure that this scenario and mark scheme aligns with the most up-to-date guidelines from the UK NICE and the BNF when using it for your OSCE assessment. 

You will need a student pharmacist and an actor for this OSCE station.
