Abstract
AbstractThe peripartal period is marked by alterations in calcium metabolism to accommodate for embryonic skeletal mineralization and support bone development of offspring in early life, and serotonin plays a critical role in modulating peripartal bone remodeling. Selective serotonin reuptake inhibitors (SSRIs) are commonly used as first‐line treatment for psychiatric illness during pregnancy and the postpartum period and considered safe for maternal use during this time frame. In order to evaluate the effect of peripartal alterations of the serotonergic system on maternal skeletal physiology, we treated dams with the SSRI fluoxetine during gestation only, lactation only, or during the entire peripartal period. Overall, we found a low dose of fluoxetine during gestation only had minimal impacts on maternal bone at weaning, but there were implications on maternal skeleton at weaning when dams were exposed during lactation only or during the entire peripartal period. We found that these effects were differential between female mice dosed lactationally or peripartally, and there were also impacts on maternal mammary gland at weaning in both of these groups. Though SSRIs are largely considered safe maternally during the peripartal period, this study raises the question whether safety of SSRIs, specifically fluoxetine, during the peripartal period should be reevaluated.
