Assuming that it could be used in a NON-abortifacient manner, Alice Lloyd correctly noted that Plan B has been used in Catholic hospitals under strict provisos. However. Pro Life physicians/scientists are indicating this to be a misinterpretation/misapplication of Directive 36 of the USCCB's Ethical and Religious Directives for Catholic Health Care Services (ERDS):
- Patrick Yeung Jr., M.D. and Donna Harrison, M.D, have explained "Why Catholic Hospitals Should Not Dispense Plan B."
- Dr. Rebecca Peck and Father Juan Vélez, MD have noted that: "The use of LNG-EC and associated rape protocols should be abandoned, because there is no safe period to give LNC-EC during a woman’s cycle when it may be efficacious to prevent pregnancy without significant likelihood that it will have an abortifacient effect" (National Catholic Bioethics Quarterly, Winter 2013).
- Drs Chris Kahlenborn, Rebecca Peck, and Severs have indicated that "current Catholic rape protocols that allow for the dispensation of LNG-EC if the woman is determined to be in the preovulatory period, appear to be faulty and should be revised" (Linacre Quarterly, February 2015).
