What Are Histamines ?

Most of the knowledge that we have on this chemical substance has simply been lifted from human pharmaceutical books. Usage of other antihistamines on dogs isn’t well documented either. Before delving into whether can dogs take Allegra, we must first learn how it works. When the body is subjected to allergens, histamine is released. This chemical is produced as a response to inflammation. Once in the bloodstream, it is carried throughout the body where it looks for cells with specific histamine receptors. It attaches itself to these receptors and swelling occurs.

The area may itch and we experience allergy symptoms. We have two types of histamine receptors in the body namely H1 and H2. H1 receptors are present in the smaller blood vessels such as capillaries. Once they come into contact with histamine, they cause the blood vessels to dilate and fluid may leak out. When this occurs, the affected part swells and we may feel an itch.

What About Antihistamines ?

At this stage, we may experience difficulties in breathing too. The second type of histamine receptors increases our heart rate. Hydrochloric acid in the stomach is also secreted and this is how they cause stomach ulcers. Thanks to modern medicine, there are drugs that block how histamine affects our bodies. They are called antihistamines. Allegra is made from an antihistamine. Drugs showcasing antihistamine effects are used in preventing allergies and in reducing stomach acidity.

Antihistamines are classified into two based on which type of receptors they bind to. There are even a few antihistamines capable of binding to both H1 receptors and H2. Allegra specifically inhibits how histamine attaches itself to H1 receptors. When administered to dogs, swelling is prevented and they no longer itch. Allegra is preferred as it has been proven not to cause increased heart rates or stomach acidity.

What About Over The Counter Tablets ?

Even though it is freely available over the counter, you should not administer it to your dog without instructions and supervision from a certified veterinarian. While veterinarians can legally prescribe it for use in animals, it has not yet been approved by the FDA. Allegra finds its primary use in treating common allergic reactions like dermatitis and rhinitis.

For best results, it should be administered to dogs as soon as itching starts and before it gets worse. It should be used consistently. The most common allergens that affect dogs are mold spores, smoke, common pepper, sometimes dander and a few prescription drugs. How do dogs react to allergens? Their skin turns red and it itches, they scratch themselves more often, they sneeze continuously and they may even induce vomiting by eating grass. Older dogs lick the affected parts. Allergens may originate from nature, the food they eat or even from external conditions you may not be aware of. Tracing the source of their problems may at times be a wild goose chase.

What Happens When Allergy Symptoms Strike ?

I think when they struggle with any of the allergy symptoms above, you should take them to the vet. He/she will carry out appropriate tests and advise you on the best treatment. You shouldn’t give them Allegra without an appropriate diagnosis. If you have an allergic dog, you should evaluate your house instead of administering Allegra regularly.

Ensure that all floors are swept and cleaned regularly before dust accumulates on them. Vacuuming rugs and carpets do wonders too. Air purifiers fitted with appropriate filters also eliminate allergens that would have otherwise been hard to eliminate in the regular cleaning routines. Even though Allegra is safe for dogs (when prescribed by vets), a few dog breeds especially the smaller one shave side effects. It should be administered with caution to pregnant dogs and those with kidney disease.

What About Allergy Home Remedies ?

I think they may experience vomiting and sedation when Allegra is administered. Are there any Allegra home remedies? If you notice your dog scratching due to an itch, dissolve two tablespoons of baking powder in water. Apply this mixture to the itchy part. Clean him thereafter with cool water for at least ten minutes. Some pet owners claim that adding mineral oil helps in reducing the itch. Many times, we see vets prescribing Allegra for dogs with allergies. It is worth noting that Allegra doesn’t cure allergy and it is only a temporary solution. You should, therefore, eliminate the source of the allergens that trigger these reactions to your canine friend.

I think a thorough diagnosis of your home will help in eliminating these sources. Vets do not recommend leftover Allegra as it is known to be toxic. You are already aware that different pet allergy drugs are made of different chemicals. Some of the allergy medicines considered safe for human consumption have lethal effects ton pets.


Dogs that have severe allergies should not be given human medicine. Vets argue against administering human medicine as dogs require different dosages. When consulting with a vet, you should also inquire about how much Allegra you should give your pet. As a rule of thumb, dogs need 2 milligrams of Allegra for each kilogram they weigh.

For instance, I think if your dog weighs 80 pounds, he should have 80 milligrams of Allegra. Canines require antihistamines in larger dosages as they are generally less efficient. While dogs can be tolerant to large dosages of Allegra, you should never exceed the recommended dosage in every eight hours. In rare cases have we seen vets recommending over dosages. While Allegra works on humans, you should first consult a vet and be safe rather than being sorry.
