DrFirst has been at the forefront of electronic prescribing of controlled substances (EPCS) since it sent the nation’s first electronic prescription of a controlled substance. As EPCS became legalized nationally, many states are considering mandating the use of EPCS for all controlled substances. In addition, to handle the opioid epidemic, prescription drug monitoring programs (PDMPs) are operated and mandated at the state level. Our interactive EPCS map is a useful tool for learning EPCS and PDMP information in your state. Click on a state for more information.
