Self-medication phenomenon is one of the acute health problems more important in women, because they have encountered critical periods such as pregnancy. Current study has been aimed to determine the prevalence of this phenomenon and some of its correlative factors in pregnant women referred to Iranian Hospital-Dubai. In this Descriptive cross - sectional study, 450 pregnant women referred to Iranian Hospital-Dubaiwere selected randomly, and examined using interview and questionnaire. Given the high cost of drug production andunpredicted adverse effects of self-consumption, especially during pregnancy whichcan lead to abnormal birth, it is necessary to raise the level of culture and lack of self-medication, particularly in women.
