Johnson & Johnson has recalled Simponi injection devices because of their potential to deliver a substandard dose of the arthritis treatment, according to a report in Fierce Pharma.

The recalled devices are in the U.S. and Germany, and European officials warned that it could spawn a shortage of Simponi injectors.

However, patients can use prefilled Simponi syringes instead. The Simponi recall stemmed from a manufacturing problem in Switzerland. Dow Jones reported many of the affected lots were set aside before hitting the market, but some 395 of the prefilled injectors made it past the wholesale level. European authorities said new injection pens will be available by the end of the month, but regular supplies won't return until May. They're recommending no new patients start treatment with the pens until the supply issue is resolved.
