I have serious doubts about usinng Daliresp due to side effects. I am a 72 yr old male with COPD Stage 4, hypertension(treated), AFib (treated with Flecainide), glaucoma, and arthritis. I am currently taking atenolol for heart rate, montelucast, the aforementioned Flecainide, ranitidine for mild stomach upset, a diuretic, and Eliquis for blood thinner.
