Sorry RLebo, I have no experience with Ezetimibe or know an ITPer who has used it. Almost everything has low platelets or unusual bleeding as a side effect it seems - I think statins may but haven't checked. The problem with checking a platelet count is that on any given day, or hour, it can be this or that, up or down, so who know if Ezetimibe caused the 27k or it was just down at that time and up some time after the test.
What was the count before 44k, how long were you on Ezetimibe when it was checked & 44k, when was it 27k - when was it last checked & the results?
It is important that your hematologist (with a count of 44k I'd want to be under the care of a hematologist) and your cardiologist are in cahoots with each other! When I was diagnosed with Graves I had my hematologist and endocrinologist talking with each other to help decide what the best treatment for me would be. Obviously you are having some problems since you have a cardiologist so you have 2 health issues that need to be worked with as what is best for both.
Good luck and keep us posted!!
