Johnson & Johnson and Procter & Gamble were among the companies hit with a flurry of class action lawsuits in New York, Florida and Louisiana federal courts over their sale of over-the-counter decongestants, following a finding by an FDA advisory panel that phenylephrine, an ingredient in many allergy and cold medicines, is ineffective as a nasal decongestant.

And the attorneys who filed the lawsuits include Darren Kaplan, a partner at Kaplan Gore in New York, who represents a plaintiff, Sandra Yousefzadeh. Yousefzadeh’s filing says she purchased two packages of 24 tablets of Sudafed based on defendant Johnson & Johnson Consumer Inc.’s representation that Sudafed PE was an effective nasal decongestant.
