In the urban areas under study the overall prevalence of self-medication was 26.2%. Predictive factors for self-medication seem to be, a high level of education, professional status and length of waiting times for a medical consultation in cases of a severe health problem. Further research on this subject is needed to confirm the reproducibility of these results, since potential selection bias could have been introduced due to the method used for patient selection. Pharmacoepidemiologic research is feasible in Portuguese community pharmacies.
