Benadryl is somewhat sedating. Also has anticholinergic effects.
For people with Sjogren's it might be too drying. Zyrtec is a less drying but still a strong antihistamine. Males with prostate issues have to be careful with these two antihistamines.

I only take the antihistamines at night.

Also Gabapentin and Lyrica have a warning about skin itching/allergy potential. They also can affect breathing causing shortness of breath.

You could try Allegra. But it has been my experience that Allegra is weak in action. But it is non-drying and for those people with sensitivity to the drying effects, it is worth a try.
I think Claritin is useless, and also it has potential for raising liver enzymes.
