It's not often that the FDA gets sued for anything, but a powerful Philadelphia legal firm that handles whistleblower and class action cases throughout the nation, Sheller, P.C., has petitioned the Federal Court to demand the FDA follow through with black box warnings for Johnson & Johnson's drug Risperdal or remove its pediatric approval. The FDA had ignored Sheller's requests to allow the legal firm to release documents held by drug company Johnson & Johnson and its subsidiary Janssen that would prove the necessity of withdrawing the FDA's 2006 approval of Risperdal for pediatric prescriptions or at least demand black box warnings.
