Abstract

Background and Objectives: Pharmacological and non-pharmacological treatments for nipple fissures have been investigated, with a variety of options yielding promising outcomes. Herbal treatments have also shown effectiveness, albeit with contradictory outcomes. Our objective was to evaluate the effectiveness of a topical blend containing lanolin, beeswax, and olive oil (RepoGen cream) in nipple fissure relief. Material and Methods: This study was a randomized, double-blind, placebo-controlled clinical experiment conducted at a teaching hospital in Qom, Iran, between March 2023 and 2024. Participants were mothers with singleton pregnancies who intended to breastfeed their newborns. The intervention group applied RepoGen cream to the nipple area before and after breastfeeding, while the control group applied placebo cream with no active ingredients. At 3 and 7 days postpartum, women and newborns were evaluated for nipple complications and breastfeeding behaviors and function. Results: A total of 133 mother-infant dyads were enrolled, with 63 assigned to the RepoGen group and 70 to the control group. The RepoGen group demonstrated significantly lower nipple pain on both Day 3 (63.5% vs. 42.9%, p < 0.001) and Day 7 (84.1% vs. 71.4%, p = 0.01). The incidence of nipple wounds was also significantly reduced in the intervention group at both time points. Multivariate logistic regression analysis confirmed significantly lower odds of nipple pain, redness, wounds, and bleeding in the RepoGen group on Day 3, with sustained reductions in redness and wounds on Day 7. Although feeding frequency did not differ significantly between groups, the RepoGen group exhibited a significantly lower number of wet diapers on both days (p < 0.001). No maternal or neonatal adverse effects were reported throughout the study period. Conclusion: The current study confirmed the effectiveness of RepoGen cream for routine care in relieving nipple fissure symptoms among breastfeeding mothers without causing adverse effects. These findings suggest that RepoGen is a safe and effective intervention for improving maternal breastfeeding comfort during the early postpartum period. © 2025 Elsevier B.V., All rights reserved.
