Interactive Drug Analysis Profiles

Interactive Drug Analysis Profies (iDAPs) are complete listings of all suspected adverse drug reactions reported to the MHRA via the Yellow Card Scheme. These can be accessed from the iDAP section of the MHRA website, along with guidance for their interpretation

The inclusion of a particular reaction on a iDAP does not necessarily mean that it has been caused by the drug. Reporters are asked to submit Yellow Cards even if they only have a suspicion that a medicine may have caused the adverse reaction. Many factors must be taken into account in assessing the likelihood that a drug has caused a reaction, iluding the possible contribution of other medication that a patient may be taking and any underlying disease that the patient may have. There may be reasons an individual or group of individuals might be at greater risk of a reaction.

The number of reports for a particular medicine cannot be used to determine the commonness of a reaction, as neither the total number of reactions occurring, nor the number of patients using the drug is known. It is also known that many factors can influence reporting on a particular medicine, e.g. media references or a raised profile of a medical condition.
