Abstract

Objective Neutropenia developed after continuous intravenous infusion of ritodrine hydrochloride (Yutopar) for preterm uterine contractions in a twin pregnancy. We successfully returned the low neutrophil count to the normal range after discontinuation of infusion of ritodrine and treatment with granulocyte colony stimulating factor (G-CSF). Case Report A 34-year-old woman with twin pregnancy was treated with ritodrine for preterm uterine contractions at 27 weeks and 6 days gestation. Neutropenia developed after continuous intravenous infusion of ritodrine for about 4 weeks. We ceased the ritodrine infusion immediately and treated the neutropenia with G-CSF. A cesarean delivery was performed the day after cessation of the ritodrine infusion because of uncontrolled preterm labor. There were no adverse side effects or infectious complications in the mother or the newborns. The maternal neutrophil count recovered to the normal range 4 days after administration of G-CSF. Conclusion Based on prior case reports and the clinical presentation of our case, G-CSF may be a useful treatment for pregnant women with ritodrine-induced neutropenia. However, more clinical studies are required to confirm the safety and efficacy of this treatment.
