The dose being released up front just means that you might feel withdrawal issues before you take the next dose and that it maybe won't work quite so well, it's not going to harm you aside from that. If the Pristiq fixes your sex drive from depression or increases it since it does that to some people then it might take a while for your sex drive to return to normal, or if you slip back into depression it might get worse.
Thanks for the reply : It may be true that I am experiencing early withdrawals. Could dissociation be one of them? I had been taking Pristiq in halves for a while. It was not good on my body. I would get these brain "pangs", it would feel like someone shook my brain and I would lose all focus. The withdrawal symptoms from Pristiq are horrible. I have never experienced anything like it. If you are feeling strange in anyway I would talk to your doctor and see if they can prescribe you the dose you need.

To anyone else reading Well- how did it work for you?
I feel like I am going crazy on the full 50mg and want to try to cut them in half to see if it helps calm down the anxiety it causes me right after I take it. The Dr. I want to go off it but I'm pretty nervous. Does anybody else have high blood pressure from this wicked pill? As a response to whether or not you are supposed to cut them in half I take mg a day and my appetite is out of control. The doctor told me to cut a pill in half twice a week to reduce the amount in my system.
So I take every day except monday and thursday and then I take a 50 split pill. Splitting them makes your body absorb them a little quicker but I haven't felt any effect from it. The lower dose keeps me from binging in front of the fridge all the time.
This is the 1st medicine that has actually worked for me. I am five days into discontinuing my 50 mg of Pristiq and still feeling dizzy and generally crummy. I took Pristiq for 18 months. How long before you felt better. I was in a similar boat, I'm very sensitive to meds. I can't speak to weaning off it, though, as I obviously haven't needed to. Side note, I haven't really had any side effects to speak of on it, which was a welcome change for me.
It killed my sex drive for a while, but that nonsense stopped eventually, so a little patience may take care of that issue for those who run into it? Start new topic. Recommended Posts. Posted April 24, Link to comment Share on other sites More sharing options Hey, Well, since you say that other ADs haven't worked for you, that makes me think that maybe you should give Pristiq a try - I mean, if you're running out of drugs to try, do you really want to pass up on one that might really help you?
