Alvogen Inc. is voluntarily recalling two lots of Fentanyl Transdermal System opioid patches.

A small number of cartons labeled "12 mcg/h Fentanyl Transdermal System patches" actually contained 50 mcg/h patches, so Alvogen is recalling the 12 mcg/h lots.

The 50 mcg/h patches that were included in cartons labeled "12 mcg/h" are individually labeled as 50 mcg/h. This transdermal system is manufactured by 3M Drug Delivery Systems in St. Paul, Minnesota.

Application of a 50 mcg/h patch instead of a prescribed 12 mcg/h patch could result in serious, life-threatening or fatal respiratory depression.

Groups that could face increased risk include first-time recipients of such patches, children and senior citizens.

Alvogen has not received any reports of problems related to this issue.

The product is meant for the management of pain in opioid-tolerant patients and is packaged in cartons of five individually wrapped and labeled pouches.


The affected Fentanyl Transdermal System lots include:

  • Lot 180060 of Fentanyl Transdermal System, 12 mcg/h, expiration date 05/2020.
  • Lot 180073 of Fentanyl Transdermal System, 12 mcg/h, expiration date 06/2020.

The mislabeled product is packaged in a 12 mcg/h primary carton. These lots of Fentanyl Transdermal System were distributed to pharmacies across the country.
