the prophylactic (prevention) dose i use is 10 mg per 100 pounds body weight – weekly – orally. (also vit. d, c, and zinc) many months and zero side effects.
the 1% sterile injectable solution is 10 mg per ml.
i use the one labeled for cattle and swine, but 1% sterile ivermectin solution is 1% sterile ivermectin whatever the brand name. there are lots of brands available at the feed store. “agri-mectin,” “ivermax,” “endomectin,” etc. etc. they’re all 1% sterile solution of ivermectin. it’s the same dosage i’ve been using for years for heartworms in dogs, the heartworm dose is 10 mg/100 lb body weight, orally – but monthly. (it seems to work on ALL parasites, internal and external. my dogs haven’t been bothered by fleas or ticks for years.)
