My cat is 4 l/2. He constantly scratches his neck and licks and grooms. He also shakes his head some. He had been getting depot shots for a couple of years to treat his allergies; then his doctor took him off and told me to give him Prednisone. When I gave him Revolution 5 days ago, he had a reaction and was very uncomfortable. Constantly itching and biting himself. He must be allergic to the Revolution? What else could he be allergic to?

Hi BBtoo,

If you think your cat has had a reaction to the Revolution medication please contact your vet for help. Prednisone is a steroid medication. This article Allergies - Skin may be helpful before you talk to your vet about your cat's problems.

Take care!

It is possible to be allergic to anything, including Revolution. You can have your cat tested for allergies (intradermal skin testing) by a veterinary dermatologist but it may not change the way your cat is treated. It's interesting that your veterinarian took your cat off long-acting anti-inflammatory injections (which are correctly called "repositol" injections but sometimes referred to as "depot" injections as the medication's brand name is "Depo-Medrol") and put him on oral Prednisolone. This isn't usually as effective but can have fewer side effects if that's a concern. However, most cats rarely have side effects to either drug (not true of dogs or people.) Ask your veterinarian what she thinks.
