Trends of Over-the-Counter and Prescribed Medication Use During Pregnancy: A Cross-Sectional Study

Abstract

Background: Globally, unjustified medication use during pregnancy, a critical phase in human life, is a threat that compromises the safety of both, the mother and the child. We aim to investigate the prevalence of over-the-counter (OTC) or non-prescription and prescription medication use during pregnancy in women from the city of Riyadh, Saudi Arabia, the level of prior knowledge, and the sources of their information about medication hazard/safety. Methods: A cross-sectional study was performed using a self-administered questionnaire for 287 pregnant women visiting King Saud Medical City (KSMC) – outpatient departments for routine antenatal care during 3 months (1st Mar–31st May 2021). The questionnaire was developed by Navaro et al with 4 sections: socio-demographic data, medication use during pregnancy, level of knowledge, and relevant sources of information. Results: The participants had a mean age of 32.21 years ± 6.41 (SD), and gestational age of 23.67 weeks ± 8.47. About 76.66% of them reported using medication during their current pregnancy: predominantly prescribed (86.36%). Women who used medication during pregnancy were slightly older; the mean difference was 1.97 years (95% CI 0.23–3.71) (P=0.027). Women living in an urban environment as compared with rural had a higher prevalence of medication use (79.01% vs 52%) (P=0.002). Overall, 58.19% reported using non-prescribed medications during pregnancy, with analgesics as the most frequently used class (70.30%). The mild nature of the illnesses and availability of an old prescription and information from pharmacists were the main reasons for self-medication. About 40.77% denied receiving any information about medication use during pregnancy. Conclusion: The prevalence of the medication use during pregnancy in our population is alarmingly high. Analgesics were the most frequently used. Lack of adequate information from treating physicians appears to be contributory to self-medication during this critical time.
