GLOSSARY OF MEDICAL TERMS IN LAY LANGUAGE





The CSM Working Group on Patient Information recognises that users may not be familiar with the
terms used in patient information leaflets to describe unwanted effects of a medicine.

In order to promote consistency and to aid production of clear and understandable leaflets, the
MHRA and the Working Group have developed the attached list of medical terms with suggested
wording suitable for lay readers to describe possible adverse effects of a medicine. The list is not
comprehensive and further terms will be added in the future.

Principles for developing definitions:


1. How to use these definitions: the wording of each leaflet should be considered individually

to ensure that the specific information for that medicine is conveyed accurately and in a way
that is comprehensible to most of the intended readers. User testing will help to identify if
there are specific problems in comprehension or interpretation. This should focus in
particular on any areas where the patient has to take action if an adverse effect is suspected.


2. When to use lay definitions: definitions should be used when the medical term is not well

known in the general population.

3. Level of detail: it will be appropriate to include more details to enable the reader to identify

possible symptoms of an adverse effect where this is a key safety issue and the patient
should take action to prevent further harm. It may be appropriate to group effects into broad
categories such as “heart problems” and provide a lesser degree of detail for very rare and
minor effects where specific instructions on action are not needed.


4. General format: the standard format is to describe what the condition is and then what a

sufferer may feel. This latter is to help patients in identifying whether they may be suffering
from the effect described. This may not be necessary if the condition is well known or the
symptoms obvious from the description of the condition.


5. Inclusion of medical terms: pharmaceutical companies should also consider including the

medical term where this is an important feature and may help the reader interpret other
sources of information about the medicine.


6. Where to use these definitions: these definitions should be used to describe adverse effects

of the medication. They may also be used in other sections such as warnings but may not be
necessary. For example, a patient suffering from myasthenia gravis would usually recognise
the name of the condition. However, a brief description of the type of condition may be
helpful to other users.


7. Alternative wordings: there may be circumstances where alternative wording is considered

more appropriate, in which case justification should be provided.

8. Serious: use this term to indicate that the condition is usually medically significant (e.g. is

likely to require medical attention, such as hospitalisation). For example, Stevens-Johnson
syndrome causes serious blistering and anaphylaxis is a serious allergic reaction. This is not
necessary when the seriousness of the condition is obvious or well known.


9. Severe: where necessary to distinguish from symptoms or medical effects that might

otherwise be considered as mild (e.g. severe headache, or severe pain accompanying
myocardial infarction).
