Objective to evaluate antiviral treatment, duration, and side effects on pregnant women based on gestational age and severity of COVID-19 infection. Method: a systematic review of antiviral treatment, duration, and side effects on pregnant women based on gestational age and severity of COVID-19 infection. Systematic review was conducted following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) Statement. Result 948 papers accessed through Pubmed, Scopus, Science Direct, Cohcrane, and other with keywords “Antiviral”, “Pregnancy” “Pregnant” “Coronavirus” “COVID-19” “SARS-CoV-2”. Duplicate papers were excluded (n=302), topics and abstracts that do not meet the criteria (n=612), and 25 papers that did not meet the inclusion criteria. 9 papers that meet the inclusion criteria (case reports and cohort retrospective case study) discussed 20 pregnant women with COVID-19 infection (16 moderate and severe cases received Remdesivir, 3 moderate and mild cases received Lopinavir-ritonavir combination, and 1 moderate case received Arbidol). Conclusion, remdesivir is an antiviral frequently used in pregnancy on trimester II and III with severe COVID-19 infection with a duration of treatment of 5-10 days. Remdesivir should be monitored because some show side effects of increasing liver function. Key word: Antiviral, Pregnant, COVID-19
