The government is investigating 120 deaths among users of patches that emit the painkiller fentanyl and warned patients Friday to be sure to use the powerful narcotic properly to avoid accidental overdose. The Food and Drug Administration is probing whether any of the deaths are related to inappropriate use of the painkiller or factors related to the product’s quality.At least some may have been accidental overdoses, and reports suggest patients or prescribers weren’t aware of crucial safety information on the drug’s label, said FDA’s Dr. Robert Meyer. That prompted Friday’s unusual public health advisory.
