Merck & Co. was stung with two major legal setbacks over the withdrawn painkiller Vioxx on Thursday when a federal jury in New Orleans ordered the drugmaker to pay $51 million to a heart attack victim, and a state judge in New Jersey overturned a November verdict favoring the company.

In New Orleans, the jury found that Merck “knowingly misrepresented or failed to disclose” information about Vioxx to retired FBI agent Gerald Barnett’s doctors. It said Barnett, of Myrtle Beach, S.C., should get $50 million in compensatory damages. And it added $1 million in punitive damages, saying Merck “acted in wanton, malicious, willful or reckless disregard for the plaintiff’s rights.”
