What is Polaramine for dogs?

Dexchlorpheniramine (commercially known as Polaramine) is an antihistamine with anticholinergic properties used to treat allergic conditions. As an antihistamine, it acts on the effects caused by histamine, which are mainly associated with allergies, but also with gastrointestinal ulcers. The compound dexchlorpheniramine in Polaramin does not stop the production of histamine in the body, but tries to compete with free histamine, thus alienating the action of the allergen in the body.

Antihistamines form a very large group of drugs and have been used in human medicine for decades with great success. The problem is that they are not as effective in dogs. Therefore, they are usually not the first choice for treating allergies such as allergic dermatitis from flea bites or DAPP, canine atopy or food allergy or shock anaphylaxis, i.e. severe allergic reactions.

What is Polaramine used for in dogs?

Some antihistamines can be used in dogs. Although their efficacy is considered moderate, and they have no immediate antipruritic effect, the veterinarian may prescribe them for mild itching or insect bites, for example. They have been observed to improve the symptoms of atopic dermatitis when administered together with omega-3 and omega-6 fatty acids. This effect may reduce the dose of corticosteroids, the drugs normally used for these allergies.

The antihistamines that have been shown to be most effective in atopic dogs are clemastine, the combination of chlorpheniramine and hydroxyzine, or oxatomide. As we can see, in this case the veterinarian could prescribe Polaramine, although it usually has to be combined with other medications.

There is a debate about the effectiveness of polaramine in dogs. Some say it may not be as effective, but others think it will relieve allergy symptoms in your dog. Polaramine takes effect in the body after only 1-2 hours and your dog begins to recover. However, the progress or full recovery depends on your dog and the type of allergy they have.

Dosage of Polaramin for dogs

Dosage and method of use are the sole responsibility of the veterinarian and depend on the clinical picture of the dog and its size.

Polaramine is also marketed in various dosage forms such as tablets, syrup, injection, or ointment. It is recommended that Polaramine be swallowed whole, as it is formulated to be absorbed slowly by the body. If the dog chews it in small pieces, its effectiveness may be reduced.

The most common way of administration is tablets. The dose is a 2 mg tablet 2-4 times a day for dogs under 15 kg and a 6 mg tablet 2-4 times a day for dogs over 15 kg. Increase the dose only if your veteran allows you to.

Polaramine may also be administered as a liquid syrup through feed or water. However, be sure to measure the dose correctly.
