Applications of Oclacitinib Maleate

  • Oclacitinib is labeled to treat atopic dermatitis and itchiness (pruritus) caused by allergies in dogs, though it has also been used to reduce the itchiness and dermatitis caused by flea infestations. It is considered to be highly effective in dogs and has been established as safe for at least short-term use. Its efficacy equals that of prednisolone at first, though oclacitinib has been found to be more effective in the short term in terms of itchiness and dermatitis, long-term safety is unknown. It has been found to have a faster onset and cause fewer gastrointestinal issues than cyclosporine. While safe in the short term, oclacitinib’s long-term safety is unknown. While some say it is best only for acute flares of itchiness, others claim that it is also useful in chronic atopic dermatitis.
