What Is Piriton?

Piriton is the brand name of over the counter medication containing the antihistamine chlorpheniramine which is a antihistamine that is commonly used to relieve the symptoms of allergies and hayfever, insect bites and stings and skin rashes and hives. Piriton and chlorphenamine works in both humans and dogs by interfering with the action of histamine, a chemical that is released by the body of humans and dogs during allergic reactions, thereby reducing allergy symptoms like sneezing, runny eyes and nose, sneezing and itching.

Piriton, available over the counter in the UK in forms like tablets and syrup, requires a consultation and a veterinarian's prescription for animal use. While it's commonly used to treat allergic reactions in humans, Piriton can cause drowsiness due to its sedative effects. Therefore, if you are considering administering a antihistamine for dogs, it is crucial to consult your vet and follow their guidance before administering Piriton to your dog

Histamine, Allergic Reactions and How Piriton Can Ease Your Dog's Allergy Symptoms

Can dogs have Piriton?

Allergies, those pesky and often irritating immune responses in your dog that usually come on in the warmer summer months, are your dogs body's way of reacting to foreign proteins like pollen or insect venom. These proteins, actually named allergens, are typically harmless to most humans and dogs, however, if your dog happens to be sensitive or allergic to a specific protein i.e. grass pollen for example, their immune system transforms into a hypersensitive sentinel constantly seeking out and dealing with the invading proteins. It is this state of high alert or sensitivity that results in a cascade of allergic reactions if even the tiniest amount of the allergen enters the body and histamine takes center stage in these reactions.

When your dog's immune system identifies an allergen, it goes into overdrive to deal with the it, launching a full-scale attack on the foreign protein. This attack results in the release of histamine into your dog's system, which then sets off a series of responses. In most cases, the symptoms triggered by histamine release in your dog are localised, meaning they are confined to a specific area of your dog's body like it's eyes or nose or body. This localised response is your dog's body's way of containing the perceived threat. For example, if your dog is allergic to pollen, histamine release might cause itching, redness, and swelling in your dog's eyes and nose, a classic hay fever response. Believe it or not, food can cause allergies in some dogs and a well balanced, non allergenic diet for your dog is important for their long term health. High quality, bespoke dog foods like Different Dog, Tuggs or Butternut Box (read our Butternut Box review here and use our Butternut Box discount code to get 50% off your first two boxes) can be tailored specifically to your dog to ensure that it is allergen free and that they are eating a perfectly balanced diet.

Anaphylactic Shock In Dogs

In severe cases of allergy, your dog's immune system's reaction may not limited to a particular body part as the histamine release is severe and widespread. it goes global. This dramatic response by your dog's body to an allergen is known as anaphylaxis, and can be a potentially life-threatening emergency. During anaphylactic shock, histamine and other inflammatory substances flood your dog's bloodstream, affecting nearly every system in your dog's body. Anaphylaxis can cause a range of potentially severe symptoms, which can include:

  1. Breathing Difficulty: The airways constrict, making it hard to breathe.

  2. Drop in Blood Pressure: This can lead to dizziness and a feeling of impending doom.

  3. Skin Reactions: Hives, itching, and flushing are common.

  4. Nausea and Vomiting: Gastrointestinal symptoms can be severe.

  5. Loss of Consciousness: In severe cases, anaphylaxis can cause unconsciousness.

Whilst fairly rare, if your dog experiences anaphylaxis then time is of the essence. Immediate veterinary attention will be required. Epinephrine, a life-saving medication, will potentially be administered to counteract the widespread effects of histamine and other inflammatory molecules in your dog's body. Without prompt intervention, anaphylaxis can rapidly progress to a fatal outcome.

Is Piriton Safe for Dogs?

Although generally safe for dogs it is essential that you obtain a prescription for Piriton from your vet before administering it to your dog. Piriton is mostly safe for dogs when given at the correct rate and dosage, but its active ingredient can pose potential risks when interacting with other drugs your dog may be taking. There are a range of drugs that can interact with chlorpheniramine, the active ingredient in Piriton therefore, it's crucial to consult with your vet before giving your dog a Piriton tablet, especially if they are currently taking any other medications or suffer from any pre existing health issues. Establishing the correct piriton dose for dogs is crucial in order to keep them safe and healthy.

How Piriton Works In Dogs

🐾 Sneezing

🐾 Runny or blocked nose

🐾 Coughing, shortness of breath, and wheezing

🐾 Watery, red, or itchy eyes

🐾 Skin rash or hives

Piritons active ingredient acts by blocking your dogs histamine release mechanism, thus preventing it from signaling your dog's body to respond to the allergen. This calming of the histamine response provides your dog with relief from these distressing allergy symptoms.

Piriton Dose for Dogs

Determining the correct piriton dose for dogs is something that your vet can provide guidance on and it is super important for their safety to ensure that the correct dose is given and any adverse effects are minimised. The dosage varies based on your dog's weight.

🐶 Small Dogs (Under 9kg / 20lbs): Small dogs weighing under 9kg (20lbs) can take 1/2 a Piriton tablet, which is equivalent to a 2mg dose.

🐶 Larger Dogs (Over 9kg / 20lbs): Larger dogs, weighing more than 9kg, can safely consume between 1 to 2 tablets, not exceeding a maximum dose of 8mg.

It is always essential to consult with your vet before giving your dog Piriton for the first time and whilst administering Piriton it is essential to follow to these guidelines to ensure your dog's well-being. For general reference please refer to this Piriton for dogs doseage chart

Understanding Piriton For Dogs & How It Works

Before administering any new medication to your dog including Piriton, it is imperative to be aware of what you're giving them and the associated risks. As discussed, Piriton, also known as chlorphenamine, is an antihistamine used to treat allergic conditions in both humans and pets. It's available under various other brand names, in both tablet and liquid forms. While Piriton is generally safe for dogs, it's crucial to be cautious of other allergy tablets that may contain potentially harmful ingredients like amphetamine, caffeine, pseudoephedrine, or alcohol. In the event of accidental ingestion of these substances, seek immediate veterinary assistance.

Did you know? Chlorphenamine maleate, the active ingredient in medications like Piriton, was actually discovered back in the late 1940s by a Swiss chemist named Daniel Bovet? His research led to the development of one of the earliest and most effective antihistamines, changing the way we treat allergic reactions. Bovet's groundbreaking work earned him the Nobel Prize in Physiology or Medicine in 1957, highlighting the immense impact of chlorphenamine maleate on the field of medicine.

Piriton vs. Piriteze For Dogs: Important Differences

Is Piriton safe for dogs?

It's important to differentiate between Piriton and Piriteze, as they both contain distinctly different active ingredients despite having very similar names. Piriton's primary active ingredient is chlorpheniramine, which as has been shown above is generally safe for dogs. Piriteze contains the active ingredient cetirizine hydrochloride, which again is safe to administer to pets but only under guidance from your vet. When in doubt, it is essential to consult with your vet who can prescribe Piriton as it is generally considered safe for dogs and is often recommended by vets.

Can I Give My Dog Piriton Every Day?

Piriton is generally safe to administer on a daily basis provided the correct dosing regime is followed and you have consulted with your vet beforehand. While some dogs may need Piriton before outdoor adventures in the spring and summer, it's essential to exercise caution. Allergic reactions in dogs, similar to humans, result from their response to airborne pollen. However, consistently administering Piriton to your dog should only be done under the guidance of a vet, with a well-defined long-term plan.

Possible Side Effects of Piriton in Dogs

Piriton may cause some side effects in dogs, including:

  • Drowsiness

  • Diarrhea

  • Dry mouth

  • Vomiting

  • Changes in behavior

Establishing the correct piriton dose for dogs is crucial in order to keep them safe and healthy. Drowsiness can occur, similar to humans, but it's generally not a cause for concern unless excessive. If your dog experiences persistent diarrhea when taking Piriton then it would be prudent to seek veterinary advice. Ensure your dog has access to plenty of water to combat dry mouth. In the case of vomiting after taking Piriton, determine whether your dog is spitting out the tablet. If vomiting persists, consult a vet. Behavioral changes are uncommon but should be monitored closely, with professional medical attention sought if significant alterations occur.

Natural Remedies For Itchy Dogs

If you are looking for a more natural remedy for dogs with itchy and flaky skin one of the best places to start is your dog's diet. For many dogs a tailored, high quality food regime can have marked effects on allergies and itchiness. Quality dog food suppliers like Tuggs, Butternut Box and Different Dog provide superior quality food that can be tailored specifically for your dogs needs and can help to relieve allergies and itching. Another natural supplement that has been shown to help is salmon oil for dogs.
