I am currently taking Pristiq 50mg in the afternoon around 6:00 because I have to take my Adderell XR 25mg (think i spelled that wrong) in the morning. The first two weeks of taking Pristiq I felt awesome was back to my old self again. But after that I just went downhill now all I want to do is sleep, can't stay awake at all. I am not sure what could be wrong nothing has changed in my medication.
I just want to know what is going on will the tiredness ever go away? I have not had the energy to do anything but lie around and sleep. Also I am on pain medication for my back and knees and they are not working like they use to after I had taken the Pristiq for two weeks also.

What condition are you taking Pristiq for, may I ask?

major depression and signs of bipolar
March 25, 2009 - 8:57pmMaryph2002, who is monitoring your drug protocol? Are you trying other options to managing depression? Have you been diagnosed with a chemical inbalance that triggers the bipolar disorder and depression? Or is it due to emotional, environmental/life factors?
March 25, 2009 - 9:13pmMary, I'm so sorry you're dealing with this. It's very frustrating to try to manage conditions with medicines that have inconsistent effects on us, isn't it?
And then when we find something that we think is working -- Hallelujah! -- but then if things change and it doesn't work after all, we almost feel lower than we did before we started.
Have you asked your doctor about your side effects?
Was it your doctor who recommended not taking the anti-depressant and the Adderall at the same time?
Can you tell us what pain medication you are on?
I am wondering if somehow the Pristiq has affected the way your Adderall is working. I take Adderall as well, and when it's not working, I too feel completely sluggish.
I went and looked up the side effect information on Pristiq. Here is a page that talks about them, as well as cautions and interactions:
http://www.drugs.com/pristiq.html
One of the cautions includes a note about special conditions that might require dosage adjustments or special tests to safely take the medicine, and one of the conditions they list is bipolar disorder. Is there a reason your doctor preferred this medicine for you even with this caution?
Do you have another appointment with your doctor soon? The web says that this medicine is monitored fairly closely for the first 12 weeks.
Did you ever take Effexor? If so, what was your experience with it? I ask because Pristiq is that drug company's newest anti-depressant, and the formula is apparently quite similar.
Have you had any other symptoms, like dizziness, nausea, sweating, constipation or decreased appetite?
I hope that you will call your doctor's office and at least talk to the nurse about your side effects. You shouldn't have to be feeling the way you are, and clearly, something needs to be adjusted or checked. While fatigue is listed as a possible side effect, you can't function with the way you're feeling. Please let us know how it goes.
March 27, 2009 - 9:41amPristiq can cause insomnia. The fact that you are taking it at 6pm is most likely the reason you cannot sleep. It shouls be taken in the morning regularly along with your Adderall. I am taking both meds and if I take either one past 11am then I know I will not sleep well. Good Luck. I can relate to what youmare experiencing. Alexandra
October 1, 2009 - 3:13amim a paramedic student but what i have learned is there synapes that take place with pain receptors which allow u too feel pain. i think what might be happening is the the drug pristiq ,which also blocks certain chemicals is stronger then the opiod antagonist-(which prevents u from feeling pain is being taken by the place of pristiq) therefore it is not allowing the drug to block ur pain .
January 12, 2010 - 1:23pmI am curious on if I am going to have the same problems. I wish you luck as starting today I am on Adderall 15mg in the morning, pain medications, Pristiq I just began taking tonight and then if I can not sleep Xanax or Temazepam. I haven't taken Temazepam as I need to be able to wake up in the middle of the night with my two children as my husand works nights. I have had a problem with depression in the past but most recently it has been brought on by my pain and then a hystrectomy at age 29. I have read via internet posts etc that this is a combo that has worked for others. I would possibly speak with your doctor about getting on an alternate drug to Adderrall and seeing if that helps at all. I know in the past if I have been on something for a extended amount of time or in combo with some things loses its effectiveness

How did you do last night? Were you able to sleep?
One of the previous posters had mentioned that one of the side effects of Pristiq can be insomnia. I am wondering why you are taking it at night; did your doctor want you to do so?
Here is the page from drugs.com that tells all about Pristiq; scroll down until you get to side effects:

What is your pain from, Anon?
January 22, 2010 - 8:18amGive it time the first little boost in mood is not the effective part that comes later several weeks a gradual improvement in mood, and if you stay on it at least a year most people (about 80% or more) )recover from the depression completely, if it is a Major Depressive Disorder.
July 24, 2010 - 11:20pmwhen you say recover completely do you mean that you can come off meds? I have been on Pristiq for about a yr .
