Adverse
Drug Reaction Adverse Drug Reaction (ADR) is any
response to a drug which is noxious, unintended, and which occurs at
doses normally used in man for preventive treatment, diagnosis or therapy
of disease or for the modification of physiological function.
People vary in their individual responses to medications. Pre-approval
testing with a limited number of subjects does not reveal all possible
adverse side-effects of the medication being researched. Only when the
new medication hits the market and millions of people use it, ADR becomes
apparent.
If you suspect an adverse drug-related
event, particularly if unusual, report it to us.
