Can I Give My Dog Allegra?

Can I give my dog Allegra?Skin irritations, runny eyes, and sneezing are some signs that may indicate an allergy, and you might be considering Allegra for your dog. When we are exposed to allergens that are common in the environment we are in, some of us who are hypersensitive to those common allergens develop allergic symptoms such as those previously mentioned.

In the same way, dogs have certain allergies, too, and it is fairly easy to identify when they are having an allergic reaction because of the obvious symptoms of wheezing, itchy eyes, stuffy nose, and even skin reactions. While humans rely on antihistamines to reduce the effects of allergy in their bodies, is it also safe to give dogs an antihistamine such as Allegra?

Allegra is a popular brand name of Fexofenadine or Fexofenadina in Spanish. It is an antihistamine known for effectively reducing the effects of histamine, including itching, watery eyes, and sneezing due to certain allergens. Although allergens are mostly harmless substances in our surroundings, dogs with allergies are affected in many ways when they inhale or ingest these allergens.

Can I Give My Dog Allegra? Answer: Yes

Some of the most common allergens in dogs are dander, mold spores, dust, feathers, cigarette smoke, some food ingredients, and prescription drugs. If you see your dog manifesting these symptoms: red and itchy skin, watery eyes, increased scratching, sneezing, vomiting, diarrhea, and constant licking, they are most probably showing signs of allergies.

Taking your dog to the vet is the first thing to do when allergic reactions arise. Your vet will most probably conduct a thorough examination of your dog to identify what is causing the allergy. This then will lead to knowing the best treatment for them. A standard medication that vets give to dogs suffering from an allergic reaction is an antihistamine such as Allegra. The antihistamine works to block the effects of a substance or chemical that triggers the allergy symptoms.

Dog allergies are not uncommon. Seeing your dog suffer from the symptoms of certain allergies is quite bothersome because we know that itchy eyes, runny nose, constant sneezing, and skin irritations can bring so much discomfort. Dog allergies come in different types, based on what causes the allergy. It can be external allergies, food allergies, and/or environmental allergies. This is why taking them to the vet for a thorough check-up will help you identify what your dog is allergic to and how you can best treat your dog.

To reduce the effects of the symptoms, vets usually prescribe over-the-counter antihistamines like Benadryl, Claritin, and Allegra. Allegra has been given to dogs with allergy, and has been proven safe and effective as long as it is given for the right purpose and within the correct dosage.

According to Drugs.com, the use of Allegra in dogs showed, “no evidence of toxicity was observed at oral doses up to 2 mg/kg.”

Other Side Effects of Allegra in Dogs

Among all antihistamines in the market that are prescribed to dogs with allergies, Allegra is considered to have the fewest side effects. Your dog might experience mild stomach upsets and dizziness, but this is rare when given medication under proper administration. If your dog manifests severe side effects after taking Allegra such as coughing and vomiting, contact your vet right away.

K9 Allergies & Your Environment

When your dog has an allergy, it might be a sign for you to accomplish some tasks for your home. Make a strong effort to clean your home by sweeping and mopping the floors, and vacuuming rugs and furniture. Pet dander can reach every part of your home and so try to eliminate them to the best of your ability. Try getting an air purifier with a HEPA filter to help catch the allergens that cannot be eliminated with simple cleaning.

Home Remedies for Dog Allergy

Skin irritations will definitely cause a lot of itching and scratching. Get rid of that by mixing baking soda in cool water, and pour it on the itchy parts. Try bathing your dog in oatmeal dissolved in cool water for about ten minutes to also lessen the itching. Mineral oil might also help in reducing the itchiness in a certain area. Just pour it on a cotton ball and swab it in and around the area.

Thank you for the answer. Is there a way to know the correct dosage to give a dog? My dog is 24 pounds and I have the 10mg Allegra tablets.

Hi Angie. I’m going to do some more research and post the suggested dosage within the next couple of days. I realize this is really important. Thanks for asking.

Angie because your dog is small you have to start out with a low dose. A 10mg tablet would be the max I’d start out with. Try to see if you notice a difference with just one.

Hi. My Cocker Spaniel weighs 33 pounds and I´m giving her 80mg daily. I chose Allegra because is the only one that works except for cortisone.

I am considering an increase in the dose to 120mg daily. What do you think about it? Thanks!

James September 25, 2013

Breno in my opinion 80mg should be working if your dog is 33 pounds. Do you not see any results at this dosage? Do you notice anything different at all? I would be very careful about increasing that Allegra dose but I am not a vet.

My vet did ok giving my 10# min pin 2.5mg of Zyrtec, but I was looking to switch to a pediatric dose of Allegra due to inclusion of a decongestant. My min pin has congestive heart failure due to cardiomyopathy and I’m just trying to get her some relief from the symptoms, generally unrelated to allergies, but similar symptoms.

Please do not confuse congestive heart failure as having anything to do with allergies, or a condition that would be relieved by a decongestant. Congestive heart failure requires digoxin to make the heart beat more effectively, and Lasix to pull off extra fluid stressing the heart. A antihistamine such as Allegra or Benadryl will work for itching, scratching, compulsively licking the paws.

If your dog is not having these symptoms, it doesn’t need an antihistamine and CERTAINLY not a decongestant. Remember that the products with the “D” for which you have to sign, relieve sinus congestion in people. Truly, the symptoms may seem the same, but clinically they are VERY different. Also, keep in mind how small your dog is…given that her heart is enlarged you don’t want to do anything that would stress the liver or the kidneys. Please speak with your vet so that you have a better understanding of the interplay of the organs most especially in a dog the size of yours.

Hi, my Labrador has been constantly dealing with allergies and leaks his paws. We have tried Benadril but it makes him drowsy. I was thinking of switching to Allegra which comes in 180mg tablets since I take it myself. Can you recommend the right doze for his weight? – he is 76 lbs.

Judy February 16, 2014

In my own experience, Benadryl did nothing for my dog. She had actually chewed a wound into her hind quarter, and as she walked she would bring up her hind legs as though to scratch.

I called the vet and got her some Atarax, an otherwise very effective antihistamine, but like the Benadryl, it did nothing to relieve her symptoms. After reading as much as I could about the Allegra for dogs, I tried the 180 mg tab for my 75 lb Airedale, She has been symptom free since.

Thanks for your feedback, Judy

My dog started on Cyclosporine (generic and cheaper [at Costco] version of Atarax) and it worked great for about 2 years. Now it has no effect. Tried Benadryl with no results and I’m looking for the info you provided. Here’s hoping my boy can get some relief.

BTW, if you’re not a Costco member, you are still allowed to get your meds there. Just tell them you’re going to the pharmacy. It’s a couple of dollars more without a membership but much cheaper than most other pharmacies.
