At the moment, I only occasionally give Akira Zyrtec to tackle her allergies, but only at the dosage recommended by the vet herself. Therefore, at least I have correct
dosing information for this antihistamine. But, I can see what Dr. Becker is talking about here. And, I have used a human pharmacy in the past for my previous cat. At that time, however, I was already familiar with the dosage I needed to give to the cat for IBD, as I had picked it up so many times at the vet's office.
