any long term side effects for giving zyrtec for allergies? Uni had a bad reaction to some flea bites. After a trip to the vet we now have her and Scraps on Comfortis. The Dr suggest I give a 1/4 pill of zyrtec daily for allergies. She just got a steroid shot yesterday, so she's feeling better now thank god. I know steroids are not good to give too often, but are there any known side effects for giving anti histamines long term? |
