My Heart Dr Has Just Prescribed Cartia XT 120 Mg

my heart dr has just prescribed Cartia XT 120 mg capsules for me. I have been taking Dr. Sinatra's products for couple of weeks which include Omega Q complex Is this going to be a problem for me, should I discontinue the Omega Q complex I didn't know I was going to be charged for this. Can't afford that right now. thank you anyway
