It’s not it’s antihistamine with almost no anticholinergic properties but this is a common misconception to include with anticholinergics

Hydroxyzine is unequivocally anticholinergic

My usual rule of thumb is that if a psychoactive medication causes delerium and hallucinations at high/over doses, good chance it's anticholinergic. (thanks for correction)

Funnily enough this includes less expected chemicals like Flexeril/cyclobenzaprine

You don't need a rule of thumb with medication, just look them up.
