The parasites ivermectin treats don’t cause itching as far as I can tell. And the most common infection with the symptom, pinworm infection[0] isn’t treated with it. I’d also be careful with scaling medication just by weight. Just because that’s how it’s often done in humans, it doesn’t work across species, because it usually depends on some enzyme’s activity levels, and they can vastly differ. That’s why almonds kill dogs, for example. 0: https://en.wikipedia.org/wiki/Pinworm_infection https://en.wikipedia.org/wiki/Pinworm_infection
