Non-prescribed drug use and predictors among pregnant women in Ethiopia: systematic review and meta-analysis

Background The use of non-prescribed drugs are common to pregnant women. It may lead to undesirable effects, such as birth defects. Study results on the occurrence and predictor of non-prescribed drug use among pregnant women throughout Ethiopia are highly variable and inconsistent. Therefore, the objective of this systematic review and meta-analysis was to estimate the pooled prevalence of non-prescribed drug use and predictors among pregnant women in Ethiopia. Methods We systematically searched studies from the international databases, including PubMed, EMBASE, Web of Science, Science Direct, Google Scholar, the Cochrane Library and others. The meta-analysis was conducted using Stata15. I-2 test and Egger's test were used to assess the heterogeneity and publication bias respectively. The random-effect model was used to estimate the pooled prevalence of non-prescribed drug use at a 95% CI. Results Eleven studies with a total of 4492 pregnant women fulfilled the inclusion criteria and were included. The pooled national level non-prescribed drug use among pregnant women was 30.38% (95% CI: 20.28, 40.48). The highest use of non-prescribed drug among pregnant women was observed in Amhara region 36.71%, while the lowest was in Tigray region 9.67%, respectively. The most frequently consumed non prescribed drugs by pregnant mothers were paracetamol 34.38%, amoxicillin 14.73%, aspirin 4.25%, metronidazole 2.81% and ciprofloxacin 2.80%. Maternal previous history of self-medication, maternal illness during pregnancy and maternal marital status were significantly associated with women non-prescribed drug use during pregnancy. Conclusions The overall prevalence of non- prescribed drug use among pregnant women in Ethiopia is relatively high, and varies across different regions. The most frequently consumed non- prescribed drug by pregnant mothers was paracetamol. Maternal; previous history of self-medication, illness during pregnancy and marital status were significantly associated with pregnant women non-prescribed drug use. Awareness of the possible side effects of taking non-prescribed drugs for all pregnant women is very relevant in the media and in the maternity ward. In particular, it is important to make clear to mothers who have a history of self-medication, to those who have a history of illness during pregnancy and to those who are pregnant, unmarried or divorced.
