An Illinois judge approved a $64-million class-action deal involving anti-depressant Paxil. The agreement, under which plaintiffs can get full refunds for their Paxil purchases, settles claims GlaxoSmithKline misled consumers by promoting the drug to children.Parties in the suit originally made the arrangement last November, contingent on a hearing to determine whether the settlement was fair and whether plaintiff’s attorneys were entitled to the $16 million settlement fee they requested. Last year the FDA issued warnings against use of Paxil in children after studies found the drug increased suicidal tendencies while having questionable effects on depression.
