Johnson & Johnson’s PriCara unit has voluntarily recalled all lots of 25-microgram-per-hour Duragesic CII pain patches that have an expiration date of on or before December 2009. The recall is due to a possible cut in the lining of the internal reservoir that could cause the gel to leak. Direct exposure to the fentanyl drug can cause serious events, such as breathing problems, or even a potentially fatal overdose.
