Good Morning from the west coast.
I am on a 5mg dose for now. 5 mg seems to be a common starting dose (although I think 2.5 is the smallest dose). I had my one month "echo" 5 days ago and my cardiologist maintained the 5mg dose for me. I think that i will have monthly echocardiagrams for another couple of months and then less often. I am so grateful for Canada's socialized medical system!
All the best!
