SB 1642 Oklahoma Senate · 2026 Regular Session

Controlled dangerous substances; authorizing divided quantities for certain acute pain opioid prescriptions. Effective date.

SB 1642 allows healthcare providers to issue initial opioid prescriptions for acute pain in "divided quantities" (e.g., splitting a seven-day supply into two parts to be filled on different dates), while still counting as a single prescription under the seven-day limit. It directly affects doctors and other prescribers who treat acute pain with opioids, requiring them to use immediate-release drugs at the lowest effective dose. Key provisions include mandating "do not fill until" dates for the second part of the divided prescription and requiring documentation of the rationale for splitting. The bill maintains existing requirements like seven-day limits, thorough patient consultations about opioid risks, and prescription monitoring checks.

MODERATE
The bill was revised to transition from a House version to a Senate floor version, incorporating specific amendments to Oklahoma's opioid prescription laws. The changes add new requirements for practitioners to conduct thorough medical histories and physical exams before prescribing opioids for acute or chronic pain. It also introduces stricter rules for issuing subsequent prescriptions, such as requiring 'do not fill until' dates and limiting supplies to seven days unless specific conditions like major surgery are met. Additionally, the Senate version adds a requirement for practitioners to discuss drug risks with patients or guardians before issuing the initial and third prescriptions in a treatment course.
Scope change
The scope of applicability remains the same (practitioners prescribing opioids in Oklahoma), but the requirements for when and how those prescriptions can be issued have been expanded and clarified.
REQUIREMENT

Added a mandatory requirement for practitioners to conduct and document a thorough medical history, including substance abuse history, and a physical examination before issuing any opioid prescription for acute or chronic pain.

Added a new requirement for practitioners to enter into a patient-provider agreement with parents or guardians for patients under 18, and with pregnant women.

Modified the rules for subsequent prescriptions by adding conditions such as requiring the prescription to be due to major surgery or 'confined to home' status, and mandating a 'do not fill until' date.

Added a requirement for practitioners to discuss the risks associated with opioid drugs with the patient (or guardian) before issuing the initial prescription and again before issuing the third prescription in a treatment course.

Modified the structure of the statute to clarify that divided quantities of an initial seven-day prescription count as a single prescription for compliance purposes.
