Pfizer/Warner-Lambert

FTC approves planned merger but requires divestiture of an overlapping consumer product marketed only in the U.S., Pfizer announces May 25. While neither company would say which product must be divested, Pfizer calls the requirement "baffling." The merged firm most likely will have to "rid" itself of either the Rid or Nix pediculicides, which had a combined 58.1% dollar share in the lice category for the 52 weeks ended Dec. 26, according to data from Chicago-based Information Resources, Inc. Both companies also market mouthwashes, W-L with Listerine and Pfizer with Plax. The closing is targeted for early to mid-June, Pfizer says
