The federal judge managing the multidistrict litigation over the birth control pill Yaz last week declined to certify a proposed national class of users allegedly harmed by the contraceptive, and struck the class action allegations from the complaint. In re: Yasmin and Yaz (Drospirenone) Marketing, Sales Practices and Products Liability Litigation, No. 3:09-md-02100 (S.D. Ill.).

In the opinion, Judge Herndon noted that named plaintiff Plaisance was a 44-year-old citizen of the State of Louisiana who was prescribed YAZ in May of 2006 by her physician. During the summer of 2006, plaintiff was hospitalized due to a deep vein thrombosis (“DVT”) in her left leg. She alleged that the DVT, as well as other adverse effects, were caused by her ingestion of YAZ. Plaintiff sought class certification of a nationwide class of YAZ purchasers who contracted DVT, but in the alternative proposed separate state-wide classes.
