McNeill PPC and the FDA have issued a voluntary recall of brand name only Zyrtec, Tylenol, Benadryl, Motrin.  The recall is referencing "NDC #s" not individual lot #s and expiry dates.  The NDC #s can be found on the upper right of the product label, just above the product name. 

The FDA and McNeill PPC are stating that these products "may contain a higher concentration of active ingredient than is specified; others may contain inactive ingredients that may not meet internal testing requirements; and others may contain tiny particles". 

See the FDA release for specific product NDC #s.  (http://www.fda.gov/Safety/Recalls/ucm210443.htm)
