Prescribers in need of new controlled substance prescription forms should ensure they order from an approved printer listed on the DOJ website. New prescription forms with serial numbers formatted in the manner prescribed by SB 149 may be available by early to mid-2020. Confirm with the printer that the form meets California’s serial number requirements for 2021 before ordering forms. Consider moving to e-prescribing for controlled substances which is expected to be mandatory January 1, 2022.
