Camzyos changed my life. I am very sensitive to drugs as well. I was nervous to try it and my cardiologist gave me great information to help me feel confident in starting Camzyos. I have been on it for 9 months now and had a few difficult moments when I didn't feel well. I am currently on 15 mg once a day and my Valsalva went from 86 to 19. (lower than 30 is normal) I feel better and am able to walk regularly, read out loud to students without losing my breath and generally function at a higher level. (i used to have to park very close to the entrance of a building, couldn't use the stairs, and absolutely could not walk uphill) I take Metoprolol 75 mg twice a day. I travel a fair amount and my heart feels way better now as i fly. I hope you find the information you need to try Camzyos. It really is a hassle to have an ECHO so often as they track your results, but I have found the effort quite worth my results. Since we have so many similarities, I want to add that I am 61 years old, work full time , do not drink alcohol or take any other drugs except my heart meds. I hope my experience helps you. I find the MAYO clinic blog very helpful on this journey.
