CHICAGO (AP)- The federal government's new advice to doctors for helping smokers quit recommends the drug Chantix, which has recently been linked with depression and suicidal behavior. The new guidelines mention the psychiatric risks but also say the popular Pfizer Inc. drug is the most effective at helping people get off cigarettes.

The guidelines mention other options, too, and highly recommend combining counseling and medication. But doctors are encouraged to talk to all smokers who want to quit about trying medication.

The ad campaign for the cholesterol-lowering drug Lipitor that features artificial heart pioneer Dr. Robert Jarvik has been halted by drug maker Pfizer. A U.S. Congressional committee examining consumer drug advertising has been looking into whether the ads misrepresented Jarvik and his credentials.
