I've had a good amount to drink tonight. Is it safe to take an allergy pill?

I’ve had a few drinks tonight and stupidly went into my basement where there’s dust and other allergens. So now I’m sneezing and wheezing – which is a typical reaction that’s usually cleared up with some Zyrtec or Allerclear or something similar (I have the generic).

But is it safe to take with alcohol in my system? I’m trying to keep my liver in good shape – it’s bad enough as it is. I know you’re not my doctor, but any input? I’d prefer to be able to breathe again and to stop sneezing so I can, you know, sleep.
