Health: pharmaceuticals; co-prescribing of naloxone with opioid drugs; require. Amends sec. 17744b of 1978 PA 368 (MCL 333.17744b).
SB 401 requires doctors to co-prescribe naloxone - a medication that reverses opioid overdoses - whenever they prescribe opioid painkillers. This directly affects healthcare providers who prescribe opioids and their patients, mandating that naloxone be provided at the same time as the opioid prescription. The bill amends existing law to make this co-prescribing a standard requirement, not an option. It aims to reduce opioid overdose deaths by ensuring patients have immediate access to naloxone when prescribed opioids. The bill passed the legislature with strong support on July 1, 2025.
