We followed the prescription of psychotropic drugs by primary health c
are physicians over a 3-year period. The material consisted of 1000 ra
ndomly selected adult primary health care patients. At least one psych
otropic drug was prescribed to one third (n = 307) of the sample durin
g the follow-up period. The most commonly used drug category was that
of benzodiazepines, which was prescribed to 24% of the sample. An anti
depressive was prescribed to 8%, a neuroleptic to 2% and ''other psych
otropic drugs'' to 10% of the sample. The most important predictor for
prescribing psychotropic drugs was recognition of mental problems at
the initial survey, but age and marital status also had an association
with the prescription. No gender difference was found after controlli
ng for mental problems. Psychotropic medication was also prescribed to
13% of the patients who had no sign of mental disorder.
