Drugmaker Merck & Co. doesn't have to cover medical-monitoring expenses for Vioxx users who aren't claiming injury from the recalled painkiller, the New Jersey Supreme Court ruled.

Phyllis Sinclair and Joseph Murray sued Merck in 2004, seeking to have the company fund a medical-screening program for U.S. consumers who took Vioxx for at least six weeks. New Jersey law requires plaintiffs to show physical injury, the Supreme Court said in an opinion.

In addition to punitive damages, the suit sought to have the Whitehouse Station, N. J.-based company fund a screening program to provide diagnostic tests for each member of the proposed class and a follow-up with an epidemiologist.
