I am researching placix to see if any of his medications medications are interacting in a negative way. He has a heart stint placed in an artery in his heart in NOV. He did well for several days. Since then, he is having feelings of fullness in Chest, rapid heart beat, shortness of breath, dizziness going from sitting to standing, and can walk to our mailbox (75) feet and he has paleness in face and he has to star or sit before moving further. He takes Prilosec which maybe interacting with the placix. His cardiologist has ordered a prescription, but the druggists had to order it. Do u have any suggestions?
