Forgot to give my dog cetirizine. Can I give the missed dose now?

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/ )

There is no age limit for Cetrizine in dogs; however, it is given based on the weight of your pet so please ask your vet what the appropriate dose would be for Pepper. You can use it on puppies. However, it doesn't have much drowsy effects, so it may not work as well as you are hoping for the puppy. I would instead try to exercise your pup during the day or right before bedtime to tire her out. : ) Best of luck with your puppy Pepper moving forward. Take care.

You should see an improvement of symptoms within a few hours of administration. If not, you can discuss a different antihistamine, OTC or prescription, with your veterinarian. Just as in people, different antihistamines may be more effective in different dogs. Allergies can be frustrating to diagnose, so discuss allergy testing, hydrolyzed diets and food elimination trials with your veterinarian in addition to antihistamine use.

Hi and thanks for your request. Once daily (once every 24 hours, so every day at 2am) would be correct. The dosage you are giving is on the higher range, make sure you do not exceed 20mg per day. https://www.petcoach.co/canigive/dog/zyrtec/

Antihistamines, like cetirizine, don't often work well in dogs. It is worth a try to use them but dogs metabolize them so quickly they just don't have the effect you would expect in most cases. Also, remember, if his scratching is not due to an allergy then that may be why it is not working. After 4 hours you should have noticed it working already.

Yes, you can use either one of those antihistamines. For loratidine you can give 10mg (1 tablet) for Cetirizine you can give 20mg (2 tablets). If after one dose she is not better you should have Bonnie examined by your vet.

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.
