More than 150 women have settled lawsuits against Yale University after suffering severe pain during IVF procedures at its fertility clinic, where a nurse replaced fentanyl with saline. The nurse, Donna Monticone, who was sentenced in 2021 for tampering with a consumer product, had replaced 75% of the fentanyl with saline to fuel her opioid addiction. Plaintiffs reported their concerns were dismissed by staff, leading to prolonged suffering. While the details of the settlements remain undisclosed, lawyers indicated they included significant financial compensation. Yale has since implemented new safeguards to prevent future incidents and acknowledged the need for systemic changes. Plaintiffs expressed hope that this case will lead to better patient protections in medical settings.
