Your dog may have been prescribed a drug called Cytopoint, which is a convenient monthly injection for dogs. The active ingredient is a monoclonal antibody (Lokivetmab), which targets a protein called canine interleukin-31 (IL-31). This inhibits IL-31 from contributing to inflammation and in doing so, provides relief from pruritis (itchiness) associated with allergic dermatitis, and the treatment of clinical manifestations of atopic dermatitis in dogs.
It is important that any potential allergens are avoided or eliminated including skin parasites. Complicating factors such as skin infections must be treated concurrently.
Over time the product is gradually broken down by the body so repeated injections are required to continue the effect. Most patients will respond to the first injection though some will take two doses before significant benefit is seen. There is no benefit in trying a third dose if no beneficial response has been seen from the first two.
It is only licenced for use in dogs over 3kg in weight. Side effects are extremely rare and include hypersensitivity reactions, vomiting/diarrhoea, neurological signs or immune mediated disease. It is safe to use with most other medications.
