Can I give my puppy Cetirizine or Loratadine for an allergic reaction?

Yes, you can give cetirizine as needed. Be aware that if you use it constantly there is a chance he will become tolerant to it and will no longer work. It should also not be used in animals that have any underlying kidney or liver disease. Please review this article on the medication in regards to dosing, side effects, etc. ( https://www.petcoach.co/pet-medication/cetirizine/ )

You can give her an antihistamine tablet. This is probably an allergic reaction due to an insect bite or a plant outside. those reactions tend to resolve within 48 hours without treatment. if the swelling becomes too large or if Arturo is lethargic, take her to the vet in order to get an antihistamine injection.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Yes, cetirizine can be used in puppies. However, please get in touch with your local vets to confirm the dose and frequency of administration. Your vet may want to see Thea to make sure cetirizine is the right treatment for this problem.

As long as the discharge from the nose is clear, then yes, you can try an antihistamine. Priton (chlorpheneramine) is not the best. You are better off using loratadine - 10mg by mouth once a day (should be one tablet). ( https://www.amazon.co.uk/Haylief-Loratadine-Hayfever-Allergy-Tablets/dp/6041257966 ) If the discharge is discolored (green or yellow) or he is acting ill in any other way (not eating, coughing, lethargic, vomiting, etc) then he should see a vet. Hope this helps. Best wishes.

Benadryl capsules can be used as long as it is not the Extended Release formula. Claritin (loratidine) and Zyrtec (cetirizine) can also be used in dogs. Contact your veterinarian for an appropriate dose. Do not combine antihistamines. Use just one and switch if it does not seem to be effective.

The pictures are kind of blurry but I can tell there is some redness. The swelling is difficult to appreciate. It does seem like an allergic reaction to something, but what.....I cannot say. Since she is acting otherwise normally you can try to give her some over the counter antihistamine medication - you can use diphenhydramine (Benadryl). I would give her 1/2 of a 25mg caplet by mouth every 12 hours. If this has not resolved by Monday then she should see your vet. https://www.benadryl.ca/products/benadryl-caplets

Unfortunately, by law it is illegal for the experts at Petco Pet Education Center, formerly Petcoach to give the dose information for any drug, including OTC drugs, without seeing the animal in person first. That's because doing so requires a veterinary client patient relationship which cannot be achieved via an internet forum. In addition, the experts cannot say for certain if a specific drug is safe for Rey. You will need to speak to her vet to see if it's safe to give her the Loratadine.
