so you took what like 45mg/kg? for 3 days? The longer the better as the larvae migrate up to 14 days maybe more. Also, through in albendazol for greater effect. It increases the efficacy of praz with leass side effect. One you have felt the spasming death grip of flukes with praz you will NOT wish to repeat it. Take my word. But the dose I took was one and very low.... recipe for disaster.
