My lord here we go again

C'mon guys really? Ivomec does not work on ticks. After 2 days the tick was most likely full. Either way by then it has already injected the toxins. Pyrantel does not work on tapes. Would be nice because it is cheap. Perhaps you misread the label and it is Praziquantel.
I mean really. If you are smart enough to get on here and post something. You are smart enough to make a few clicks and do the research on what things do. Ivomec is used and in most heartworm meds. It is used to treat most worms except tapes.
I posted this on another thread but here it is again. This is right from the ivomec sight.
