Allegra for cats, any concerns?

Thread Starter 
I was given an allegra prescription for my cat. Vet said no side effects but she said the same thing with dentrol and sure enough I found it can cause vomiting, which my cat did for 48hrs. Just curious of anything I should be aware of with cats on this? My cat needs to recover, especially stomach wise. I'm suppose to get a pill cutter and quarter 30mg tablets.

Looking it up further (I already knew it was a 2nd gen) it does not cross the blood brain barrier and reportedly didn't cause the typical antihistamine side effects in the lab animals.
At the right dosage it sounds like it would be a great nearly side effect free antihistamine to use, and much safer than benedryl as its definitely not anticholinergic.

Call your vet and discuss it further if you're still unsure at their prescribing this for your cat.

Does your cat take any other medications? There's a very slight chance of interaction with some drugs, but not much since fexofenadine actually doesn't really metabolize as much as other antihistamines (it would vary a bit in cats as to what exact percentage would metabolize).

We use OTC Claritin, loratadine. We get the generic variety at Wal-Mart in the 10mg tablet. Then, we cut it in half and give half a tablet daily. You can start at 1/4 tab daily and work up to 1/2 tab daily. It dissolves easily in water, so we add a teaspoon or so of water to the girls' wet food in the morning, drop the tablet in, let it dissolve, then mix it all together.

Just a reminder to check with your vet before using any medication. Claritin may not be appropriate for your cat and if it is, the vet may give you different dosing instructions.

Claritin also crosses the brain blood barrier some and metabolizes more, thus more chances for side effects and interactions with other medications. (in humans and animals -OTC doesn't mean safe to take without consulting a doc or pharmacist)

I'm pretty sure that's why the vet picked the med he did as it makes more sense.
