Twenty age\u2010gender categories were established. Use of a drug group was defined as filling at least one prescription. The variables studied were age, gender, number of prescriptions and net cost. The prevalence of use, the number of prescriptions and cost issued to each age category were reported.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The overall prevalence of drug use was 74.53% (women 80.93%, men 67.84%). This was higher in the group of 0\u20134\u2003year\u2010olds, and in the \u2265\u200a55\u2003year\u2010olds. Age (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.001) produced a statistically more significant effect than gender (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.05). The most used therapeutic groups were analgesics, nonsteroidal anti\u2010inflammatory drugs, antiulcer drugs, anxiolytics, expectorants and mucolytics. The number of prescriptions and costs per patient rose with age and showed great variation in the use of these groups for patients in different age groups. The risk of prescription in women was 23% higher than in men (RR 1.23, 95% CI 1.11, 1.37, <jats:italic>P<\/jats:italic>\u2003&lt;\u20030.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The majority of subjects were exposed to one or more drugs.
