I've read up on Azithromycin and have to say that anything that causes heart rhythm problems scares me. Not to mention the cardiac deaths during the first few days of taking it. I saw on PR that it has helped a lot of people, but it's also made some people worse. I don't want to take that risk either. I wonder what would happen if I skipped the Azithromycin and only took the Melpron. I read that taking it alone has effects on malaria -which makes me think it might do something for the Babesia. Or maybe it wouldn't. Has anyone heard of doing this? Of course I would only do so if my doctor agreed with me.
