My cat scratches her head from food. What medicine can help?

There are no medicine safe for cats over the counter. If the steroid injection helped, then there is a good change it is from an allergy. You will have to talk to your vet about a long term solution such as a diet change or allergy testing to control the signs since long term steroid use can have unwanted side effects such as weight gain and diabetes.

Although not the typical affected areas, make sure flea are controlled as this can contribute to ther allergies. A food change may make a bit different as this can be a food allergy. You want to switch to a hypoallergenic diet; royal canin, Purina and science diet all have good diets for this. From there you may need a low dose of cortisone intermittently to help but cats can build a resistance to long term use and have side effects. There is another immunosuppressive drug known as atopica that is helping some cats now. There is another drug called Apoquel that is not labeled for cats but is showing good relief in several

Thanks for using Petco Pet Education Center, formerly Petcoach! This is likely due to allergies. Benadryl is good as is prednisolone for example. However, these are only going to help with the itch temporarily. However, it is crucial to get rid of the allergic component and treat the allergy as if not, the itch will continue. Also, it is crucial to treat the likely secondary infection. There is no at home treatments as the other medication that can be used in cats for this is a prescription medication called prednisolone. One thing you can do at home besides dealing with the possible allergies is using an e-collar which you can get from your local pet store or online to prevent any further self-trauma. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!

With itching in the face I would be worried about parasites or a food allergy. You can try changing to different formula if fiodbthat contains a different protein source or a hypoallergenic diet. There a promising allergy medicine called Apoquel that can be helpful in cats now. You can apply cortisone cream to the red area until you can talk to your vet about the new options

I can understand being nervous about steroids, but that is what helps with allergies, especially flea allergies. If you clear up all the fleas both on Cody and in your home, then likely only a short course of steroids is needed. I would speak with your vet about your concerns, and discuss trying a course of steroids, which would likely really help him.

Steroids can be indicating is allergic dermatitis but have extreme side effects when used at high doses or long term. I would not recommend this as a long term course. Any steroid over time leads to a resistance where it just won't work anymore and can lead to liver problems and diabetes in cats. Prednisolone is better tolerated and seems to work better in generally in cats compared to dexamethasone. There is a medicine called Atopica or Apoquel that is made for allergic skin disease and does what the steroids do just without the side effects and resistance, so you may be better trying one of those instead. All are prescription medicines so you will have to call your vet to see if they can fill this since they already have a medical report on her. I would stay on the hypoallergenic diet as this can take 2-3 months for max affect and treats count as far as food allergy go, so make sure those are hypoallergenic or don't give any. I would consider a treatment for mange and fleas also. It is not common in cats but causes them to be itchy and it is hard to prove and super easy to just treat to be safe.

If she responded initially to d/d then this confirmed a significant food sensitivity. A hydrolyzed diet such as royal canin hypoallergenic or anallergenic would be recommended, antiinflammatory medications should also be prescribed to provide short term relief
