Insys

Opioid manufacturer Insys Therapeutics has filed for Chapter 11 bankruptcy protection, just five days after agreeing to pay $225 million to settle the federal government's criminal and civil cases against the company for bribing doctors to prescribe its fentanyl-based painkiller.

Two months ago, Paul Lara saw a letter from his doctor to his insurance company. He recalls looking at the bottom of the page, next to the doctor's signature, "It says: Does this patient have cancer? He marked yes."

Only one problem: Paul Lara has never had cancer.

After decades as a commercial fisherman in Texas, Lara was badly injured on the job. In 2013, his doctor prescribed a high dose of an opioid called Subsys for Lara's back and neck pain. The fentanyl-based spray can be up to 100 times stronger than morphine.
