The World Health Organization has issued a warning about the potential for severe allergic reactions to pet allergy medications, including the new cat allergy drug, M-Cat.
According to the W.H.O. the drug, which was approved for use in cats in July, is “not yet effective in humans,” and is “possibly dangerous for some patients.”
The warning was issued after M-cat was first used in a clinical trial in dogs in October, which had a 1 in 8,000 chance of causing a severe allergic reaction.
The W.O.’s statement says the drug’s ingredients are unsafe for human use, and that there is no data showing that it’s safe or effective in cats.
