Yeah ive seen the quercetin interactions and side effects- I take ECGC? (NOT SURE I have the spelling right- it’s basical.y green tea extract) which seemed to have less adverse possibilities.
The possible alzheimer’s risk though is concerning for ivermectin- not sure though how much of a risk it is.
ALZHEIMER’S risk is really about the CYP2d6 issue not clearing out the neurotoxins.
Ivermectin would be put in the category in my opinion of any drug potential problem that crosses the blood/brain barrier that is not suppose to cross..
So it would go like this...if a drug is known to cause neurotoxin issues if it manages to cross the barrier then it could be a risk. Way too much is unknown about brain diseases.
And if on top of that you have an enzyme issue in the brain whereby it doesn’t adequately clear neurotoxins you then have an additional problem
