Defining emergency opioid antagonist as including an expired emergency opioid antagonist for a person rendering aid to another in reasonable need of medical assistance.

HB 2436 allows anyone providing medical assistance during an opioid overdose to use an expired emergency opioid antagonist (like naloxone) up to 10 years past its expiration date. This directly affects bystanders, first responders, and community members administering overdose reversal drugs. The bill amends Kansas law to explicitly include expired antagonists in the definition of "emergency opioid antagonist," ensuring they can be legally used in emergencies. This change increases access to life-saving treatment by removing expiration barriers during urgent situations. The law also maintains existing immunity protections for people seeking help or administering aid during overdoses.
