Household storage and use of medications in a population served by the family health strategy in Brazil

Objective. To identify families served by the family health strategy (FHS) storing medicines at home, to evaluate storage conditions, and to investigate medicine use practices.Methods. The study was conducted in a municipality in the state of Sao Paulo with two FHS units serving 1 867 households. The sample was selected by means of stratified random sampling. Data collection was conducted through semistructured interviews from July to October 2008.Results. One resident was interviewed in each of the 280 households visited. Medicines were found in 255 households (91.1%). Of 326 storage locations, 217 (75.8%) were inadequate (easily accessible to children or exposed to moisture, light). Of the 2 578 medicines identified, 2 059 medicines (79.9%) in 236 (84.3%) households had safety or identification problems. Of the 280 respondents, 179 (63.9%) used medications. Of these, 24 were self-medicating, only one with an over-the-counter drug. Only 44 users had the prescription for their medication, and 21 did not follow the prescription in terms of dosage or had interrupted the treatment.Conclusions. Non-adherence to recommended treatment can lead to negative outcomes, such as inefficiency (using dosages lower than prescribed), poisoning (using dosages higher than prescribed), and other adverse reactions.Univ Estadual Paulista UNESP, Fac Ciencias Farmaceut, Dept Farmacos & Medicamentos, Araraquara, SP, BrazilUNESP, Fac Ciencias Farmaceut, Dept Farmacos & Medicamentos, Araraquara, SP, BrazilUniv Fed Sao Paulo UNIFESP, Dept Psicol, Sao Paulo, BrazilUniv Fed Sao Paulo UNIFESP, Dept Psicol, Sao Paulo, BrazilWeb of Scienc
