The FDA has approved a new type of pain pill designed to eliminate the risks of addiction and overdose associated with opioid medications like Vicodin and OxyContin, the first of its kind in 20 years.

The prescription pills, sold under the brand name Journavx and made by Vertex Pharmaceuticals, are taken twice a day and represent the first new class of pain medications in 20 years—and the first non-opioid painkiller since that class first appeared on the market in the 1980s.

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.
