What an on-call pharmacist could advise...

You need to quickly assess and prioritise the web sources of information and advice. 

The guidelines that you find online from other NHS Trusts vary in their quality: some lack references, others are missing authors and publication dates. Those that do include references often cite a paper published in the BMJ several years ago. 

The Parkinson's UK website signposts you to the PDMedCalc tool. 

You decide to dismiss the opinions you find in several discussion forums as you can’t assess their accuracy.


The patient was taking co-beneldopa dispersible 25/100 QDS and ropinirole 2mg TDS.
PDMedCalc: recommends rotigotine 6mg/24 hour using patches. 


Therefore you advise that the patient be prescribed transdermal rotigotine 6mg/24hours. If at any stage you had felt out of your depth with this question you could have phoned a more senior pharmacist for advice: maybe a neurology, elderly care, or MI pharmacist. If not confident about your answer, you could also have asked Dr Kotecha if the answer could wait until the next working day for you to discuss with a colleague if clinically appropriate.

Follow up 

The next morning you document your recommendation and speak to the pharmacist looking after the patient. She has already seen the patient on the ward round this morning. They will titrate the dose as necessary according to the patient’s response.


Maybe this scenario makes you think you could do with a 'refresher' on solving these kind of problems. If so, then you might want to look at the Administration tutorial.
