CVS pulling some cough and cold medications containing phenylephrine

CVS is pulling some cough and cold medications from the shelves - in the wake of a Food and Drug Administration warning saying they simply aren't effective.
Those drugs contain phenylephrine as the only active ingredient - and it's found in popular drugs like Benadryl, Advil and Tylenol - amongst others.
Nearly $2 billion worth of products containing that ingredient were sold in the United States just last year.
