Is palliative sedation allowed in Catholic teaching?
Yes. The clearest statement is the 2020 Vatican letter Samaritanus bonus. It says the Church "affirms the moral liceity of sedation as part of patient care." The point is "to ensure that the end of life arrives with the greatest possible peace and in the best internal conditions." It adds that this "holds also for treatments that hasten the moment of death (deep palliative sedation in the terminal stage)." Consent still counts, "always, to the extent possible, with the patient's informed consent."
One boundary stays in place. Sedation must not aim directly at causing death, "even though it may accelerate the inevitable onset of death."
The 2025 Ethical and Religious Directives set out conditions rather than a ban. Directive 63 spells them out. Say a patient is in the terminal phase and typical pain management is not working. Then steps that induce temporary or on-and-off loss of consciousness are allowed. Three things must be in place. The first is proper consent. The second is a plan of care that covers the degree and length of sedation. The third is a chance for the person's own religious preparation for death.
That last point is worth raising with the team in advance, if the sacraments matter to the patient or the family. It is a normal request, and palliative teams make room for it.
