Fexofenadine/Allegra was reviewed and not added. This is fortunate as it's the only OTC allergy medication that actually works for me.

Same - just took a generic fexofenadine, in fact. Of course, 5 years ago, everybody thought diphenhydramine was safe, too.

But is there a "safe minimum frequency"? Generally, I try to avoid taking any medication more/longer than necessary, and my bottle of diphenhydramine is still mostly full after many years...
