I recently read that Journavx is used short term, like after surgery. And the price is outrageous...$15.50 per pill and the usual dosage is 2 a day. Medicare does not cover it. Not sure about other insurance.
This is from the Vertex site... "Vertex is also evaluating suzetrigine in peripheral neuropathic pain (PNP). The company’s Phase 3 pivotal program for suzetrigine in patients with painful diabetic peripheral neuropathy is ongoing, "
But unless insurance starts covering it, $31 a day is probably out of most people's reach.
