The company has since recalled over two million of the patches.īagolie Friedman Injury Lawyers, with affiliate offices in Jersey City and Clifton New Jersey, Hollywood Florida and Brisbane, Australia, have begun to review and accept injury cases from surviving family members and individuals who have suffered from Fentanyl overdose. Unfortunately a problem in the seal between the linings was discovered in February 2004, prompting Janssen to initially recall one group of the patches, but an additional four groups of the patch were removed from the market later in April. Sales of Duragesic earned Janssen Pharmaceutica over a billion dollars between the year 2002-2003. The inner lining only lets a certain amount of the drug into the body based on the needs of the patient, typically between 25 to 100 micrograms per hour. This drug is a powerful opiate pain-reliever held in a gel suspension between the two linings of the patch. The patch is applied directly to the skin where heat from the body activates a regular release of fentanyl over a 72 hour period. The fentanyl patch is comprised of an outer impermeable plastic shell and a drug permeable inner lining.
