Can I Give My Dog Piriton?

Can I Give My Dog Piriton?Is Piriton safe for dogs? It’s a popular question because it’s common for a beloved pet to suffer from allergies, skin reactions and even hay fever.

Unfortunately, most people medications aren’t really that safe for dogs. Their organs are susceptible to damage when given certain human meds. Canines can easily respond negatively.

That said, vets do sometimes prescribe Piriton to dogs. It’s effective for pollen allergies as it tends to get symptoms under control. Here we’ll discuss, in detail, the use this antihistamine for when your dog experiences allergy problems.

Can I Give My Dog Piriton? Answer: Yes, as directed by a vet

Piriton is a trusted medication that can be successfully given under professional consultation.

Although this allergy medicine is intended for people, lots of veterinarians prescribe it for canines with certain allergies. So yes, Piriton is generally safe for dogs but you really should consult with a vet for a proper diagnosis and for getting the dose right.

Another safe product that works very well is an anti-itch spray made especially for dogs.

Proper Piriton Dosage

Typically, a half tablet a day for a small breed is prescribed. For a larger dog, they may recommend 1 or 2 Piriton tablets per day usually until the condition clears up. Proper dosage largely depends on your dog’s age and weight but breed may factor in as well.

Allergy Aggravations & Tips

Many factors can trigger allergies in dogs especially if they are sensitive to the environment around them. Knowing more about the factors could possibly go a long way towards not actually needing to use Piriton in the first place. For example, some dogs are allergic to certain foods.

Just like people, dogs can be allergic to grass and pollen but dust mites are also a concern. Ensure that your house gets a deep cleaning, it may cut down on sneezing and coughing. Too much exposure to an environment that triggers allergies can weaken your dog’s immune system. They can even lose their appetite under such conditions.

Insect Bite Reactions

In rare cases, your dog may experience allergic reactions from insect bites. Watch out for marks on the skin and apply insect bite ointment soon after something like this occurs. It’s important to inspect your dog thoroughly after a long trip outdoors.

It’s generally safe to give properly dosed Piriton to a dog. This medication usually provides nearly instant relief.

What to Watch For

Aside from sneezing and coughing, you may notice that your dog is scratching a lot. Skin allergies are particularly troublesome as excessive itching can be very irritating. If your best buddy has long nails, the skin can even bleed from constant scratching. Inspect your dog to see if there are red patches, rashes or bumps on the skin. If you see traces of inflammation, then it can be a severe case requiring professional help.

Prevention & Remedies

Obviously if your dog is allergic to something, the best thing to do is remove them from allergens or situations that can trigger such an allergic reaction. If this isn’t possible, you can at least minimize your dog’s exposure to such allergens. In order words, try to avoid the use of Piriton because it isn’t actually a cure.

One suggestion is to place your dog on a diet of lamb and rice as this can sometimes ease itchy skin. You may need to reevaluate the type of dog food they are eating. Also, check if they’ve had their shots in recent years.

Conclusion on Piriton

Under a veterinarian’s supervision, you can give your dog Piriton (Chlorphenamine) for a skin allergy, hay fever and even house dust mites. While this product may help, there may be better options. For example, Apoquel treats canine allergies and it’s been specifically developed for pet use. In any case, being observant may greatly help to pin down exactly what’s triggering the allergies. Speak with your vet regarding the best course of action for your dog’s sake.

I have a 78 pound white Pit Bull. He suffers from skin lesions. I live in the Caribbean and we don’t have a great choice of animal meds. I’ve put my boy on Piriton but I don’t think he is getting enough. I am giving him one a day. Can you help with the right dose?


Anne July, 2015

My Australian Kelpie chewed patches of hair off her back every summer, making herself very sore in the process. She’d constantly scratch in the summer months too, but doesn’t have fleas. I’m extremely careful to make sure she doesn’t get any either. She appears to have some sort of allergy, but I don’t have a clue yet as to what. It’s a long, patient process of elimination.

I currently give her the correct dosage of Piriton for her size and weight, which will obviously differ for every dog. It helps to ease the problem, but please do not ever give Piriton to your dog without first consulting your vet. If it isn’t necessary for your pet, it could cause more harm than good.

My rescued boy came to me with many problems. He had severe ear infections, itchy skin and fistulas. He is on a hypoallergenic diet and during the pollen season he takes Piriton, as directed by my vet, three times each day. He weighs 36 kilograms so three tablets is not excessive for him. I asked my vet how long he could stay on Piriton and he said forever. My boy was taking Atopica for a year and this seems to have sorted out his fistulas. Another positive of this medication was the help with allergies, but he had to stop taking it because of side-effects. This is why he is now on Piriton.


Olga June, 2015

My vet has suggested that I give my dog Piriton, long-term as a preventative measure, to avoid a recurrence of an ear infection. Is it common practice to use Piriton in such a preventative way?


Joanne June, 2015

My dog has a real problem with her skin after walking through long grass. The affected area looks very sore. It’s just under her stomach between the top of her leg and she just will not stop licking it. Can you please suggest some cream I can use to help her? Many thanks!


Lynne June, 2015

My Poodle has just had exactly the same condition, also looked very depressed, with constant licking of her tummy and under her front legs which look very sore. I took her to the vet last night, had an antihistamine injection, and was diagnosed with a skin allergy called Hay Fever.


Joanne June, 2015

Thank you for replying. Since I have not walked my dog in long grass, the affected area on her stomach has cleared up!


Sue May, 2015

My dog, a small breed, has jumped into stingy nettles and is going mad. I’ve bathed her in warm salt water. Any other suggestions as to what I can do to make it easier for her? Thank you!


Vivienne March, 2015

Can I give Piriton to my Lhasa Apso while she’s on antibiotics? She’s on them because she has eczema around her eyes. I was wondering, could it be some sort of allergy as well?


Joe January, 2015

My American Bulldog scratches his ears and eyes. How much Piriton should I give him? Thanks if anyone can help.


Debbie December, 2014

Our vet has just told us to give our German Shepherd Piriton because of an allergy to her renal diet. We cannot change her food as she also has kidney failure. So we’re hoping it will stop or at least ease the itchy skin she has.


Jane January, 2015

What dose do you give?


Clare November, 2014

Is giving my dog Piriton going to contraindicate use of a steroid (2.5mg twice a day). In other words, will the Piriton stop the steroid from working?


Angela October, 2014

I have a miniature Schnauzer. She is 5 years old and has been biting her paws for the past 6 months. They are now discolored. The antihistamines she was given don’t seem to be working. Could you recommended anything? I had to change her food as she had kidney stones. She’s now on Royal Canine.


Leonard May, 2015

Yes Angela, Apoquel has worked very well for my 13 year old Bull Terrier. I believe a blood test may be required before a vet will prescribe it. It’s horrible for the poor dog, not getting any peace. I hope my message will help someone.


Chris August, 2014

My Westie and I are going crazy. Sleepless nights with constant scratching and biting. Treated regularly with Stronghold. No red patches of inflamed skin. Feet being constantly bitten and washed. I have had Westies with skin problems but he has never had a problem (11 years).

I seem to have spent a fortune and tried so much as a pensioner to save drugs and money at vets but to no avail. Is it where we walk our dogs or is it just seasonal and harvest mites? Can anyone give advice to help him? My friend went to a vet who gave steroids, antibiotics and Frontline spray which has made her 3yr old lifeless and depressed.


Stuart August, 2014

My Yorkshire Terrier appears to have a reaction to her food in the form of scratching. Will this medication help? She is 4.5 kg. How much should I give her?


Sue April, 2016

I hope you get an answer. I also have a 4.5 kilogram dog. What dosage of Piriton for my Jackapoo?


Rachel August, 2014

Hello again. My dog had a bad reaction to something and Piriton did not help on this occasion. I took him in for a steroid jab and the vet advised me that giving your dog Piriton is fine as long as it’s the correct dose.


Sam August, 2014

How long can my dog take Piriton for? When she stops taking them she starts scratching within two days.


Yvie August, 2014

My mini schnauzer is 7 years old and has been taking antihistamines for the last two years to control major irritation of her paws and ears. When taking antihistamines she is able to live a normal life with manageable moments of itchiness preventing secondary damage to her feet and ears.

I don’t believe she will ever be off them so I manage her dosage to keep to the minimum. This has the support of my vet. I must stress she is under supervision of my local vet and I have her health checked twice a year. I give her half a tablet twice daily and during the summer if I miss a dose it is noticeable. In the winter I try to reduce the dose to one half tablet daily but she can rarely go for a day without antihistamines.

Fortunately they work well for her but I do keep the dosage to the minimum because they can become less effective with long term use. She is fit as a fiddle and comfortable with this treatment. I hope this is helpful.


Ray July, 2014

Most pharmacies will not sell medication for use in animals (even if recommended by a vet) as they are only licensed for human use.


Beth July, 2014

My mini Jack Russel is scratching a lot and has made red patches on her skin. She had her usual flea drops about two weeks ago. I think she is having a reaction to midge bites. I want to give her Piriton but need to know what dosage to give her as she is very small – she weighs just 4.5 kilograms.


Yvie July, 2014

As always you should get her checked by a vet first. I have a mini Schnauzer who is very allergic and weighs just under 10kg. She has one tablet twice daily prescribed by a vet but I give her half a tablet twice daily and this keeps irritation to a minimum. If really bad, she gets a whole one every now and then. Hope she responds to the treatment as not all dogs do. Good luck!


Rachel June, 2014

I took my dog out this morning and could not believe the state he was in when I got him home. His face was double the size. His eyes were closed and the spots were massive. He didn’t even look like my dog. I got him home, bathed him in cool plain water and gave him Piriton. Within 3 hours he looked like his old self, just very tired.


Margaret June, 2013

My dog is on Piriton for hay fever. Can you tell me how long it takes to work? She’s been on it only 2 days now.


James June, 2013

Margaret it should start working within 24 hours but you may notice your dog experiencing some drowsiness. Of course, you need to consult with a vet because only they can recommend the proper dosage and treatment for something like Hay Fever. I hope your dog feels better soon.


Carol Freeland September, 2012

My 2 little dogs have been on Piriton for a week. Poor little mites are still scratching. Any advice please?
