Background Nitazoxanide shows adequate in vitro activity against coronavirus. The aim of this study was to describe the behavior of coronavirus disease 2019 (COVID-19) in pregnant women treated with nitazoxanide. Methodology This cross-sectional study included the files of COVID-19 positive pregnant women treated with nitazoxanide 500 mg every 6 hours, levofloxacin every 12 hours, and clarithromycin 500 mg every 12 hours. Results The data of 51 women (mean age: 27.4 ± 7.2 years) were analyzed. Eleven (21.56%) patients had to receive medical attention in the intensive care unit. There were 22 (43.13%) preterm deliveries, 21 by cesarean and one by vaginal delivery. The medical attention of this population was as follows: 31 cesareans, five vaginal deliveries, nine still pregnant, two requiring manual vacuum aspiration, two ectopic pregnancies, one requiring curettage, and one requiring hysterotomy. There were seven (13.72%) cases of preeclampsia, and there were two (3.92%) deaths. Conclusion Nitazoxanide prescription could be an option against COVID-19 in pregnancy due to its safety profile.
