“Can I give my dog Piriton Tablets?” is a popular question forwarded by many people whose pets tend to suffer from allergies.

While Piriton is formulated for humans, veterinarians sometimes prescribe it to keep pollen allergies in dogs under control. It is also prescribed to alleviate common symptoms of allergies in dogs, like:

  • Itching,
  • Scratching,
  • A runny nose, and
  • Irritated eyes,

which are usually associated with the following problems:

  • Skin allergies
  • Hay fever
  • Hypersensitivity reactions to dust mites
  • Bee and wasp stings

Depending on the nature of your dog’s allergies Benadryl might be an alternative.

How does Piriton work?

Piriton belongs to a group of medications collectively known as antihistamines. It contains the active ingredient chlorphenamine maleate, which is classified as a sedating antihistamine. It functions to prevent the actions of histamine, a substance that is produced by the body in response to the presence of foreign matter (an allergen). Histamine triggers a chain of events that results in the manifestation of classic allergy symptoms. Chlorphenamine works by blocking histamine receptors in the body, thus stopping this chain reaction.


Piriton Dosage For Dogs

Your veterinarian usually takes into consideration your dog’s age and weight, as well as the symptoms presented in computing for the proper dosage. A dog manifesting multiple symptoms of skin allergies may need more Piriton than a dog that is just compulsively scratching. The general dosage of Piriton 4mg for dogs can vary from 0.2 to 0.8 mg per kilogram body weight to be given every 8-12 hours.


Piriton Side Effects in Dogs

Being a sedating antihistamine, common side effects in dogs associated with Piriton administration include the following:

  • Nausea and Vomiting
    These are common responses exhibited by many dogs taking Piriton.
  • Loss of appetite
    The gastric response in dogs may lead to loss of appetite or a general change in the animal’s eating habits.
  • Diarrhea or constipation
    Piriton can also affect a dog’s bowel movements. Generally, more dogs suffer from constipation than diarrhea. Carefully observe your pet’s stools and his elimination habits. Constipation causes a dog to strain during elimination without much success. The dog’s stools may appear smaller and dry.
  • Thirst
    Piriton can cause an inadequate production of saliva by the salivary glands leading to dry mouth in dogs. Affected pets appear to be very thirsty thus there is a noticeable increase in their overall water intake. Other signs that indicate dryness in the dog’s mouth include opening and closing of the mouth and smacking of the lips in an odd manner.
  • Changes in behavior
    A dog taking Piriton may also display certain behavior changes, most of which are commonly confined to the dog’s sleeping habits. Some dogs find it difficult to sleep through the night, while others become more lethargic and drowsy, or even more aggressive.


Precautions When Giving Piriton to your Dog

Piriton tablets for dogs should be prescribed by your veterinarian! It should never be given to pet dogs without them first being examined thoroughly to establish whether the symptoms are caused by an allergy reaction or not.

Some may have adverse reactions to chlorphenamine maleate, the active ingredient of Piriton, which could prove to be life-threatening. Piriton can also react negatively with other medications that a dog is taking.

If your veterinarian has prescribed Piriton for your pet, make sure to discontinue use and call your doctor if he manifests symptoms such as

  • vision problems,
  • fluid retention, and
  • persistent vomiting.
