A randomized open-label trial, including 834 pregnant women, examined efficacy and recorded adverse events of ivermectin (ivc) and albendazole (alb) alone and combined (comb) on soil-transmitted helminth infections (STHs) in the second trimester of pregnancy. One abortion occurred in the alb group and 10 stillbirths (1, 5, 3, and 1) in the ivc, alb, comb, and the reference group (ref) with no STHs, respectively. Two babies were born with congenital abnormalities (1 [ivc] and 1 [ref]). The prevalence of anemia at first antenatal care (ANC) visit was 20.6% (23.7% [ivc], 21.1% [alb], 22.2% [comb], and 16.1% [ref]). Anemia was reduced to 8.5% at 36 weeks of gestation with 10.9% (ivc), 11.5% (alb), 7.7% (comb), and 6.9% (ref). Hookworm cure rates were 29.4% (ivc), 95.5% (alb), and 92.6% (comb). No severe adverse events were reported by the women after the administration of ivc, alb, or comb during the second trimester of pregnancy, but long-term pharmacovigillance is needed to assess safety of ivc, alb, or comb in pregnancy.
