Products licensed under the Small Animal Exemption Scheme are not licensed for use in food-producing animals such as chickens and it is for that reason that there is no information relating to the withdrawal period for eggs or meat following use of Ivermectin Drops on poultry.

Where there is a licensed alternative, vets will prescribe the licensed product. To treat worms – Flubenvet is the (only) licensed in feed product.

In the absence of licensed alternatives, veterinarians do sometimes prescribe this product for poultry under their own clinical judgement to treat lice in poultry.
