Yes - I saw a very interesting video the other day that educated me a lot on Benadryl - apparently it has a lot of side effects, can cause dementia, and is probably best avoided.

Occasional Benadryl is fine. The dementia risk is from correlations found in other medicines that share some of the same properties, when taken for many years.

It’s not a good idea to take Benadryl for many years, but occasional use or even for months while going through a difficult period isn’t going to cause dementia.
