The FDA on Thursday approved a new class of pain medication that provides an alternative to opioids. It will be sold under the brand name Journavx.

Journavx is the first and only approved non-opioid oral painkiller and the first new class of pain medicine approved in more than 20 years.

Despite high demand for an option like Journavx, doctors fear the drug’s price could be a major hangup for insurers, potentially limiting patients’ ability to access it.
