Pharmaceutical companies facing more than 100 lawsuits in federal court over improperly labeled birth control pills want the plaintiffs to provide pre-discovery information linking their claimed injuries to the defendants’ products.

Pantheon and Endo Pharmaceutical subsidiary Vintage Pharmaceuticals filed the request Monday in a consolidated litigation over the contraceptive Cyclafem, which faced a recall over its packaging in 2011. According to the defendants, the motion for a “Lone Pine-style” order is aimed at weeding out plaintiffs with nonmeritorious claims.
