If I am having SOB and chest pain, can I take a Lasix. I am on losartan, metoprolol, colchicine and allopurinol. I have a PMH of CHF, EF 25, HTN,sleep apnea, RBB, multiple abdominal hernia operations. I did not have health insurance for a long time but now I am going for sleep study and PPM with defib implant. I had Cardiac cath, no blocks, no stents placed.
