As a hayfever suffer I have often been offered anti-histamines, but have shied away from using them for fear of the long term detrimental effects.

Can you provide any links on the relationship between anti allergy drugs and alzheimer ?

Diphenhydramine is pretty strongly affiliated with cognitive risks (acetaminophen too).

When I must take an antihistamine, I go with loratadine (and quercetin if I have it)

I noticed my hayfever completely went away when I started TRT
