Adverse Reaction: The reporting vet advised me that another vet had prescribed Boss Pour-On insecticide for the 2 horses for the control of ectoparasites. The owner administered the product on both horses' backs as per instructions for cattle. This product is not licensed for horses. Quantity administered is unknown , but should have been in the order of 39ml as per cattle weight recommendations. Approximately 5 days later, the horses were observed to have hair loss starting over the back then progressing to the underline. Pruritus was also reported; it is not known if the horses were pruritic prior to treatment. The reporting veterinarian examined both horses on 20 Oct 2010 and also noted numerous oral ulcers 1-2cm in diameter. No ectoparasites were found, but both horses were subsequently treated with 3 weeks oral Sulfa Trimethoprim, a double dose of ivermectin and Drikill (rotenone) ectoparasite dusting powder. The condition of the animals has not changed since the reporting veterinarian's first examination. Case closed.
