I don't know about prazi but they did administer it with the nitaxanide if I'm not mistaken. I think it was the peruvian study, but I do remember it being used as a binder for it and a lotion.
I did that with albendazole and it was brutal. My skin just burned and burned. I guess the albendazole just wasn't designed for it. When I did it with the nitaxanide (daxon) I never got any strange sensations from it. But, that's just me.
That's what happened to me.
