Hi Maria. Malarone is used to treat Babesiosis. I believe it has similar ingredients to the anti-malarial Mepron. Malarone is a pill, and Mepron is a liquid (a thick, gloppy, bright yellow liquid at that!). Artemisinin is also used to treat Babesiosis.
I had a nasty case of Babs and had to treat it more than once. I took Malarone only once. For me, Mepron was more effective but everyone is different.
Good luck with your treatment!
