Get Your Dog Care Questions Answered by Experts
Hello and thanks for trusting me to help you and your pet today. I am a licensed veterinarian with over 25 years experience and would be happy work with you but need a bit more information in order to better assist you if you don't mind.
What size tablet did you give him?
Was it Claritin or Claritin-D that you gave him?
Thanks and I will respond further after you reply. There may be a slight delay while I formulate and type a thorough response or I may be offline, but if so, I will respond as soon as I am able.
Thank you for the prompt reply.
Claritin comes in 2 forms--plain Claritin and Claritin-D. Plain Claratin is loratidine, which generally isn't going to cause more than sleepiness, but Claritin-D contains pseudoephedrine, which acts similarly to amphetamines. Dogs are very sensitive and even small doses of pseudoephedrine can cause serious signs. Effects include increased heart rate, agitation, hyperthermia, and increased blood pressure.
This should be treated as an emergency and I would strongly suggest that you seek immediate veterinary intervention so that the central nervous symptoms and cardiac symptoms can be reversed with other medications.
I hope this is helpful. Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please reply so I can clarify for you.
