If is is found that the reaction is coming from an external source, you will need to discontinue use of any shampoos or other topical preparations. Also keep in mind cleaning products that you are using, since it is possible that your cat is reacting to floor cleaners, or other cleaning agents. If it is found to be drug based, your veterinarian will find a suitable replacement for the medication. If the diagnosis is Stevens - Johnson syndrome (SJS), or toxic epidermal necrolysis (TEN), both potentially fatal drug based skin reactions, your cat will need to be treated on an inpatient basis. Intensive supportive care and fluid/nutritional support will be administered, and relief for the pain that is associated with these conditions can be given.
For chronic and persistent idiopathic erythema multiforme (EM), a skin disease of unknown cause, azathioprine is often effective. Human intravenous immunoglobulin (IVIG) has been used successfully for severe EM and TEN when not spontaneously resolving, but it is often cost-prohibitive.
Your veterinarian will schedule follow-up appointments with you for your cat, depending on the cause of and severity of your cat’s skin disease. If your cat’s skin condition relapses or worsens, you will need to contact your veterinarian as soon as possible.
