My dog accidentally ate too much Zyrtec. What should I do right away?

It would help to know how much Zyrtec he may have eaten - this medication can be given to dogs but too many pills could cause symptoms of toxicity. Cardboard would be unlikely to cause a problem although again if he ate a large amount there would be potential for obstruction. I wouldn't worry too much about him eating extra food today. Even if his belly seems large as long as he seems comfortable and is not vomiting veterinary care will probably not be required. Feel free to repost your question with more details about the Zyrtec.

She should be fine but you may notice some side-effects. The most common adverse effects of zyrtec are sedation, lethargy, vomiting, drooling (hypersalivation), and lack of appetite. If the side effects last more than 8 hours you should have her examined b your vet. I do not recommend you give her any more for at least another 24 hours.

Hello, The answer to this is: maybe! Cetirizine anecdotally in very large dogs is sometimes still effective at a 20mg per day dosage, but some dogs will need up to a 1 mg/kg dose for relief. At Goose's weight, this would be three 20mg tablets. I'd suggest trying one 20mg tab per day at first, and going to three tabs per day if needed. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach.

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/

While a pill or two may not cause any harm other than increased drowsiness, if your dog got into a large or unknown amount it is best to seek veterinary care immediately or contact your local Animal Poison Control (if you are in the US you can call 888-426-4435 however there is a fee to use this service). They can provide treatment or let you know if the dose ingested is harmful. You may see signs like extreme drowsiness, or paradoxical reactions such as an increase in activity such as drooling, vomiting, etc. If you are seeing these signs, seek care immediately.

Hi, thanks for using PetCoach! Zyrtec is a human antihistamine that Vets use OFF-LABEL (not FDA approved or tested to be safe in dogs and cats) with success. Harper's sneezing could be from allergies. Please read the following links below for further information: https://www.petcoach.co/canigive/dog/zyrtec/ https://www.petcoach.co/canigive/dog/benadryl/ I wish Harper the best!

Both drugs are used off-label - meaning that they are not approved for veterinary use, so it's important to only use them as recommended by your veterinarian. Xyzal has a similar drug to Zyrtec, but is different enough that a new dose would have to be calculated by your veterinarian. This drug also has a lack of safety information for use with dogs, so I would not recommend it. I hope that helps and all is well with Mo.
