Revised IV acetylcysteine (NAC) protocol launching April 1, 2026

The revised protocol will go live on April 1 at 0700 EST.
We recognize that implementation timelines may vary by site. As poison specialists (SPIs) do not have visibility into local transition timing, health care providers are encouraged to share their transition status during consultations to ensure recommendations align with local practice. OPC is committed to supporting safe NAC administration and will work collaboratively with health care providers throughout this transition.
