ivromectin wormer, cause hardening of liver?

I know that is a side effect but if administerd properly the bennifts out weigh the risk. All you need is a small amunt to control fleas and ticks. But a little more than that to control gastric parasites 1cc of ivomec once a month is all you need. Heart gaurd has ivomectin in it but a very small dose something like.0025%.
One thing ivomec is known for is throat cancer so dilute it with water when shooting down throats which to me is best way of administration. Injection works for cattle but dogs are not cows. So the chance of intravenous administration is high.

To me personaly ivomec is the best thing that happened to dogs. Can even cure some manges under a different regiment of administration
