Anti histamines and horses

[Michellehenry]

My boy has now been prescribed long term usage of phenergran to allieviate his head shaking by our vet. It has worked wonders but I am concerned as to whether there is any long term detrimental effect to the horse in taking these tablets.

Does anyone else use these or other anti - histamines at all? It also says that they may humans drowsy. Is that the same for horses and are they illegal for any competition ?

Hi, I used Cetirizine (piriton) for approx 4 months last year with no side effects at all (no drowsiness).

two different products cetirizine is piriteze and is non drowsy piriton is chlorphenamine and very often causes drowsiness

I've used cetirizine on my mare for yrs, daily. (She has acute COPD and SPACOPD) With no side effects. I dont know about drowsyness and phenergran, but cetrizine has never made my girl drowsy even on 50 tabs a day, she even did a 15 mile ride on full dosage, and trotted back to the lorry : )

Sorry, my mistake - its actually Zirtek (Cetirizine Hydrochloride) not Piriton/Piriteze. I just buy it in bulk from my vet very cheaply as Cetirizine Hydrochloride.
