title: Drug side-effects assessed in a 'naturalistic' setting.
abstract: Drug treatment was recorded in 202 outpatients who were also questioned on the presence of 25 symptoms that may be caused by drugs. In only 4 instances was the incidence of symptoms usually attributed to a particular drug significantly higher in patients taking the drug than in patients not taking it. It is important to consider factors not related to drugs as well as the effects of other drugs when commenting on the incidence of a particular adverse reaction attributed to a particular drug.
