A week after Johnson & Johnson recalled millions of its fentanyl-filled painkiller patches in the USA, another firm, Actavis, has followed suit.

Actavis has announced that 14 lots of its fentanyl transdermal system CII patches are being voluntarily recalled as a precaution the firm says. The patches were manufactured by Corium International and sold in the USA and Actavis noted that patches sold in Europe are not affected by this recall.

The fear is that the patches may have a fold-over defect which may cause them to leak and expose patients or caregivers directly to the fentanyl gel. The US Food and Drug Administration noted that exposure to the gel may lead to serious adverse events, including respiratory depression and possible overdose, which may be fatal. The agency added that anyone who comes into contact with fentanyl gel should thoroughly rinse exposed skin with large amounts of water only and not use soap.

The Actavis announcement comes in the wake of J&J’s PriCara unit’s recall all lots of its 25-microgram-per-hour Duragesic CII pain patches that are filled with fentanyl gel. The recalled patches were manufactured by Alza Corp and sold by PriCara and Novartis’ Sandoz unit in the USA and Canada.
