First of all, is the doctor a geriatric psychiatrist? I'm guessing not, as Pristiq isn't for
anxiety, it's a stimulating antidepressant. It's also very hard to stop taking. When it works for
anxiety it's usually because the cause is depression -- this class of drugs targets norepinephrine as well as serotonin, and the for
mer is basically adrenaline. So I wouldn't do anything this particular doctor recommen
ds, I'd get a good psychiatrist who specializes in geriatric medicine.
