Hi, my 1 year old tabby went in for her boosters today and had a severe reaction. The vet gave her antihistamine and prednisone I.V. Does anyone know how long this emergency dose of antihistamine lasts? It's been a few hours and she seems o.k. But the vet said the antihistamine doesn't last long and if she gets worse we are to go to the emergency clinic.

Did they give her diphenhydramine (benadryl) for the antihistamine?
If so:
It is a fairly short acting antihistamine lasting around 4—6 hours per dose. The maximum sedative effect of the drug occurs between 1—3 hours.
but to give a more exact answer, need to know the weight of your cat and the actual dosage info (most likely, she was given benadryl to counteract the vaccine reaction, that's the most commonly used antihistamine)
