Some common medications used to treat pemphigus in cats include:

  • Pain medication: Pain medication may be prescribed to help manage pain and discomfort associated with the lesions and ulcers.

A high-quality commercial cat food that is formulated for your cat's age, health status, and activity level is generally recommended.

Some veterinarians may also recommend supplements, such as omega-3 fatty acids, to help support your cat's skin health.
