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 former is basically adrenaline. So I wouldn't do anything this particular doctor recommends, I'd get a good psychiatrist who specializes in geriatric medicine. Also, be very cautious about giving drugs that target brain neurotransmitters to anyone, but especially the young and the old. Dosages need to be different, brain development is different, and the difficulty of taking these drugs and of quitting them is different. This is especially true if your Mom has difficulty expressing what she's feeling. So until you get that kind of specialist, I wouldn't personally do anything (my psychiatrist, for example, has most of her practice treating the elderly, which is unfortunate for me because it means she's no longer available for appointments very often but it does help the elderly). One thing to consider -- does she eat very much? If she has little interest in eating, for example, Remeron can be a good drug -- it makes anyone want to eat, creating a lot of weight gain, but for someone with dementia sometimes they stop eating enough, and this drug is easier to stop taking than ssris and snris. Good luck.
thanks for the advice. She does have depression as well..mums doctor doesn't instil much confidence in me I have to say..after I told him her reaction he then prescribed another drug (Zoloft) and said it's just a matter of finding the right one that agrees with her.
Will take on board your advice re geriatric psychiatrist
