I have a old thoroughbred that got EPM 17 years ago. I treated him & he recovered but only to about 85 %. He's now 24 yo it's definitely taken its toll on him. I think it's effecting his brain & a gait irregularitie. I know most horses that get EPM don't live that long. It would be interesting to do a case study.

Thanks Steve, may need to visit you!

Is there a way to treat profolatic like with something like monthly Ivermectin or what ever?

SO? Is EPM like Lyme Disease? Sometimes Doxycycline alone works while sometimes Doxycycline mixed with other drugs work better for humans? In Babesiosis, also. Same thing.

Thank you for this information! I'm curious, is there a reason Toltrazuril is not FDA approved?

Can EPM cause twisting or wringing hocks?

Why can’t you treat EPM like you treat? Malaria with quinine seems a little simple I guess.
