My wife, 70 years old, had right hip replacement on April 24th, 2015. She suffered through a cellulite infection, taking 500mg Cephalexin and having the surgical area drained of 200+ccs of fluid. The surgery seems to be healing well but my wife is still suffering the remnants of the allergic reaction to the Cephalexin - stopped on May 23. The ortho doctor is against using a 7 Day Pack my wife s MD has suggested, using Allegara, Benadryl cream and Tagament but my wife is still itchy, with hives. Do you have any alternative to this treatment? Sinerely,
