I had a bad experience with Mepron, but that's just me. When I started treating my Babesia with that and Azythromycin, after one month I had a terrible anaphalyatic reaction after drinking soy milk. (Which, by the way, I am NOT allergic to) I stopped all my abx and started treating with herbs.
I did not take it long enough to notice any difference in my symptoms. But it was VERY expensive, I remember that. Sorry I can't help you there.
