Tonsilless --

The Mylan product is indeed a generic fentanyl patch, according to the company's own website . The company describes itself as "the market leader in generic transdermal drug delivery technology" and manufactures only generic products. Its generic fentanyl patch was approved by the FDA in 2005.

The brand-name fentanyl product is Duragesic (in Europe it's Durogesic), initially developed in 1960 by Janssen Pharmaceutica of Belgium and now marketed in the US by Ortho-McNeil Inc. (both are part of Johnson & Johnson).

Gary's post describes a difference between the generic and brand-name products in the way the drug is passed from the patch into the body. Perhaps that can help explain the problems your husband was having.

April 2006: Husband dx by dentist with leukoplakia on tongue. Oral surgeon's biopsy 4/28/06: Moderate dysplasia; pathology report warned of possible "skip effect." ENT's excisional biopsy (got it all) 5/31/06: SCC in situ/small bit superficially invasive. Early detection saves lives.
