Consumption of medicines in high-risk pregnancy: evaluation of determinants related to the use of prescription drugs and self-medication

The use of drugs during pregnancy still represents a challenge for medicine, since the majority of drugs cross the placental barrier with a potential to cause several congenital problems to the fetus, and most of them have not been clinically tested in pregnant patients. At the same time, the medicalization phenomenon, self-medication, and lack of patient information about the misuse of medicines are additional problems. Thus, the aim of this study was to evaluate the pattern of medicine consumption in high-risk pregnancies and the determinants related to this consumption pattern. In order to do so, a cross-sectional descriptive study was performed with puerperal women who had a history of high-risk pregnancy. Statistically significant associations were found between self-medication and fewer prenatal visits, and cigarette use during pregnancy and a higher number of children. According to these data, the vulnerability of this population to the risks of drug use is evident, demonstrating a gap that requires urgent interventions in health-care education.
