I have on Camzyos for 2 -3 years now. It works really well for me at the 5mg dose. If I forget to take it I really notice the moment I go for a walk. The difference is huge. I have no side effects that I am aware of although I did for the first week or two. Just minor things, minor dizziness and some tingling in the legs. If I forget to take it becomes immediately obvious upon exertion. Hoping that it continues to be a solution for me.
