RxCheck provides states the ability to easily participate in the growing movement of nationwide Prescription Drug Monitoring Program (PDMP) data sharing and integration. RxCheck was developed with support from the U.S. Bureau of Justice Assistance (BJA), using the Prescription Monitoring Information Exchange (PMIX) National Architecture specifications. RxCheck was designed with the involvement of state PDMP administrators, private industry, and the federal government. RxCheck is currently operated by BJA and is governed by the RxCheck Governing Body consisting of PDMP representatives from participating states.
