ADRs & Yellow Card data� As pharmacists we have duty to fill in
yellow cards if we come across an ADR with any drug during med reviews with patients.
� Keep a copy for yourselves and send CMS a copy (looks good on record).
� Sometimes need to know if a particular drug is cause for an ADR –can look at yellow card data though bear in mind that this info is not a true reflection of incidence, but is info on reports submitted
� Yellow card data is (for the majority of cases) better than ringing the company med info dept as they then have a legal right to know about patient details, and there is a risk of breaching patient confidentiality and obtaining consent could alarm patient etc.
� Yellow card data provides an alternative source of info when the BNF & SPC does not mention the ADR.
�Available on the MHRA website �www.mhra.gov.uk�Monographs are called:‘Drug Analysis Prints (DAPs)’
Example of monograph (fluoxetine)Key tip – MHRA website is awful to use. To find DAPs go to main site, and change last digit of web address ‘5’ to ‘742’. Will take you direct to the DAPs page.

Enquiries to refer to Medicines Information
Centres
Enquires that need to be referred to a MI Centre
� Pregnancy & Breastfeeding� Complex renal & hepatic disease� Paediatric (especially neonate) where off-licence
info is required� IV enquiries� Herbal interaction enquiries� Specialist enquiries – psychiatric drugs,
chemotherapy
Ringing Medicines Information� Each hospital has a MI Centre; then there are
regional (specialist centres e.g. Newcastle is specialist for pregnancy & poisoning).
� Some hospitals (e.g. Bradford) are not funded to provide a MI service to primary care so they may try to brush you off (they have an overwhelming number of enquiries to deal with). However, they cannot refuse to take your call as this would be against UKMi protocol.
� Try and ring MI only when the enquiry is complex, and needs specialist input. The more time you can give them to prepare the answer the better response you will get.
� Bradford MI: 01274 364598
MI requirements
� MI Centres tend to ask a lot of questions in order for them to prepare a comprehensive answer for you, so ensure you know all the details and have done the basic looking up.
Key questions to think about
when doing MI
MI Centres will ask you these questions so try to know their answers before ringing them
General questions – for all enquiries
� Is this a general enquiry or is it about a specific patient?
� What is your name?� What is your job/your role/your interest
in this enquiry?� How should I contact you?� When do you need an answer?
Adverse drug reactions� Establish patient’s age if relevant� Ask about the indication for the drug and any relevant
medical history (e.g. renal function)� List all current and recent drugs (include OTC products,
herbal medicines, drug abuse).� Consider any history of ADRs and or allergies.� Ask for the details of the suspected reaction including
signs & symptoms, and severity.� Establish when the suspected reaction began (especially
in relation to starting drug treatment) and whether the drug has been stopped.
� Ask how the patient has managed and how he/she is now.
Remember to check yellow card data when dealing with ADRs
Drug interactions� Which of the drugs is the patient already taking?
How long have they been taken for?� Has the enquirer or patient read about an
interaction somewhere? If so, where?� If the patient is already taking both drugs, have
any problems been identified or investigated?� If there is an interaction, is there any reason why
alternative drugs can’t be used instead?� What is the patient’s liver and renal function?� Is the patient taking any other medicines?� If any ongoing or future monitoring would be
required, who would do this?
Drugs in breast-feeding� Identify drug, indication, dose, frequency, route of
administration and duration of treatment.� What would happen if the drug is stopped, or not used?� Has any alternative been considered or tried?� Has mum already been taking the drug? Has the baby
already been exposed to it in pregnancy or breast-feeding, and if so have any problems been identified?
� How old is the infant, and is he/she premature or full-term?
� Is the baby well? Is there anything to suggest that the infant may be at increased risk of drug harm – such as impaired kidney or liver dysfunction?
� Who is in a position to change therapy if necessary or document your advice in the patient’s notes? Who else needs to know the answer to this enquiry?
Drugs in renal disease� Establish age, weight and height of patient.� Check the degree of renal failure, whether it is
acute or chronic, and whether renal function is stable, deteriorating or fluctuating.
� Is the patient currently taking the drug in question, if so what dose and frequency?
� What is the indication for the drug and have alternatives been considered?
� Which if any, renal replacement therapy is being used?
� Ask about the timing of any renal replacement therapy as necessary.
Drugs in liver disease� Establish the clinical condition of the patient, age, and
presumed diagnosis.� Results of LFTs (including clotting screen), biopsies and
other diagnostic liver tests. Are the LFTs stable or changing?
� What is the patient’s renal function?� If drug-induced hepatotoxicity is suspected, is the
patient currently taking the drug in question, if so what dose and frequency? What other drugs are being taken or were taken recently?
� If requesting advice on dosage or suitability of a drug in hepatic dysfunction, what is the indication for the drug and have alternatives been considered? What agent would normally be used if the patient did not have liver dysfunction?
Pharmacokinetics� Identify the drug, indication, dose, frequency,
route and duration of therapy.� Check the patient’s age, gender, weight,
concurrent medication and medical history including renal and hepatic function.
� Check if any previous drug levels have been taken and if so, check the exact time they were taken in relation to the drug and confirm the units of measurement.
� Have any interacting drugs been started (or stopped) which may affect levels?
Palliative care� If enquirer asks about compatibility of drugs in
a syringe driver, check the drugs, doses, diluent and volume. If you are unable to find compatibility data, think about alternative drugs, routes or separate syringe drivers.
� If enquirer asks about symptom control, establish indication and what drug or non-drug options they have tried already.
� If the patient is unable to tolerate oral administration, explore other routes with enquirer.
� Check concomitant medication and concurrent disease including renal and liver function.
Alternative medicine� Is the patient already taking the alternative
medicine or do they want to start taking it?� Identify the alternative medicine, indication,
route, strength, dose and frequency. If applicable, how long has it been taken for?
� Has the patient self-diagnosed the condition that they are seeking to treat? If they have, perhaps they should consider speaking to a healthcare professional first.
� Does the patient take any conventional medication? Is there any history of ADRs or allergies?
� Check the past medical history.
Substance misuse� How certain are you that the amount of drug taken and the
frequency of use is correct? Users may lie about the quantities consumed and the purity of street drugs also varies very widely.
� Has a urine screen been organised? What were the results?
� Does use of the drug relate to a single exposure, short-term use, or a persistent habit?
� How is the subject taking the drug (e.g. injection, oral)?� Is the subject taking other drugs? It may be important to
know about other substances (e.g. tobacco, prescribed drugs): some enquirers panic when they hear about an illicit drug, or automatically blame it for all the patient’s problems, and don’t ask further questions.
� If the enquirer has used drug slang terms that you are not familiar with, ask them to clarify.
� Many enquiries concern side effects, interactions or use in pregnancy.
Travel Medicine� Identify the traveller(s).� Check age, concurrent medication and medical history
(e.g. acute illness, immunosuppression, psoriasis, epilepsy, neuropsychiatric disorders, renal or hepatic impairment).
� Check whether any female travellers are pregnant or breast-feeding.
� Identify the exact destination(s) to be visited.� Find out about the nature of the travel and type of
accomodation (i.e. is traveller backpacking through rural areas or staying in a good quality urban hotel?
� Check the length of stay and the proposed travel date.
Immunisation� Identify the vaccine that is to be administered (is it live or
not?)� If it’s not obvious, ask about why the vaccine is required,
and when.� Is the vaccine really necessary? Even if it is necessary,
could delaying vaccination help solve the enquirer’s problem? Does the patient require a primary course or a booster dose?
� If relevant, enquire about which vaccines the patient has had before.
� Does the patient have any contra-indication to vaccination? Consider acute illness, previous allergy or adverse reactions, pregnancy and immunosuppresion.
� Ask about concurrent disease and concomitant medication.
Use the ‘Green Book’ available on the DoH website.
Product availability� Why do you need this product? Why is an
alternative in the BNF not acceptable?� What is the product to be used for?� Establish where the enquirer heard about the
product.� Ask for exact spelling, any known manufacturer,
strength, dosage form and country of origin.� Ask how much is needed, and when it is required.Remember to use UCLH website, can always ring
customer services at drug companies for confirmation about availability.
Unlicensed specialists like IDIS & Durbin may be able to source supply of drug.
Drugs in Pregnancy� Assess whether prospective or retrospective exposure – is the woman
actually pregnant now, or planning to become pregnant?� Identify the drug, indication, dose, frequency, route, and the duration
of exposure.� How many weeks pregnant was the woman when she first started
taking the drug?� How many weeks pregnant is she now?� What drug has the woman taken during previous pregnancies for any
similar condition?� Has the woman taken the drug in question during a previous
pregnancy?� Has the woman had any previous pregnancies and what was the
outcome?� Is there a family history of malformations or history of recurrent
abortions?� Have any investigations been performed (e.g. ultrasound scans)?� For chemical exposure enquiries additional questioning may be
needed to establish substance involved, approximate quantities, duration of exposure per day, protective measures taken etc.
Administration of medicines� If asked about administration of IV drugs think about: dose,
infusion fluid, fluid volume, rate, availability of intravenous access and whether any other drugs are being given IV.
� For drugs put down enteral feeding tubes, ask about: type of tube, where the end of the tube is, & the feeding regimen. Think about alternative administration routes or drugs.
� If the enquiry is about a patient who is NBM prior to surgery establish the drugs & doses, and the duration of expected NBM. Again, think about alternative routes or drugs.
� Similarly if a patient becomes dysphagic, ask about the drugs & doses and when/whether their swallow is expected to improve.
Hospitals have a Wrexham Maelor Hospital & NEEMMC guidelines to deal with crushing tablets enquiries (can ring company too).
Compatibility of parenteral drugs� Which drugs are currently being mixed?� Which drugs are you planning to mix?� What are the concentrations of the drugs, and what diluents
are being used?� How will the drugs be mixed and what types of IV lines are
being used?� Which of the drugs to be mixed are essential? (if not obvious)� What other drugs is the patient being given parenterally?� Is the number of IV access points limited? If so, why?� Can alternative routes of administration be considered? If
not, why?� Establish how the patient is fed – an enteral feed tube offers
a potential alternative administration route; if TPN is being used this can create additional compatibility problems.
Clinical trials
� If you are asked to identify a specific clinical trial, gather as much data as possible about the trial before trying to look for it: drug name, manufacturer, date of publication, disease area, any acronym, authors’ names and so on.
� Check with the drug company / trial rep for further info.
� Check NeLM website for info
Choice of therapy & drug dosing� Check the indication even if it appears obvious
(e.g. don’t assume amitriptyline is for depression) and the preferred route.
� Check the patient’s age and weight if appropriate.� Check the patient’s renal and liver function.� Check the past medical history to ensure the drug
is appropriate for the patient.� Does the patient take any other medicines?� Has the patient tried any other drug/non-drug
therapy already?� Does the patient have any allergies?
