- contact the local pharmacist to inform them of the ADR
- stop prescribing the drug for all patients
Report the adverse drug event on a “yellow card” because patient has been hospitalised

- capacity and resources
- concerns about medication
- necessity beliefs about medication
- practical barriers to adherence
- specific beliefs about medication
necessity beliefs about medication
he answers relate to various potential reasons for non adherence
a. Capacity and resources – a practical rather than perceptual barrier
b. Concerns about medication – perceptual barrier to adherence that relates to worries about a potential adverse consequences
c. Necessity beliefs about medication - relates to perceptions of personal need for treatment, in this case to reduce risk rather than make him feel better
d. Practical barriers to adherence - capacity and resource to adhere to treatment
e. Specific beliefs about medication – relates to beliefs about the specific treatment (statin), in this example it is implied that the patient doesn’t fully understand that this is not a treatment to make him ‘feel better’ at present.
A 44 yo man receives penicillin V from his GP for tonsillitis. He becomes very unwell with a rash, flushing, wheezing and he collapses. He is told that he has had an anaphylactic reaction to penicillin. This type of allergic reaction is mediated by which one of the following antibodies?
- IgA
- IgD
- IgE
- IgG
- IgM
IgE
IgA is found in mucosal areas, such as the gut, respiratory tract and urogenital tract, and prevents colonization by pathogens, it is also found in saliva, tears, and breast milk. IgD is found on B cells that have not been exposed to antigens. IgG is the most abundant antibody and responsible for the secondary response. IgM is the most primitive antibody and eliminates pathogens in the early stages of B cell-mediated (humoral) immunity (primary response) before there are sufficient IgG. IgE is in response to parasites and is responsible for anaphylaxis.
