Pristiq Overview

Desvenlafaxine (brand name: Pristiq, Desfax, Ellefore), also known as O-desmethylvenlafaxine, is an antidepressant of the serotonin-norepinephrine reuptake inhibitor (SNRI) class developed and marketed by Wyeth (now part of Pfizer). Desvenlafaxine is a synthetic form of the major active metabolite of venlafaxine (sold under the brand names Effexor and Efexor).

Switching from pristiq to generic pristiq
8 Replies RSS
I was switched from Pristiq to generic Pristiq which if I understand right, is really Effexor. Is there a possibility this could be causing my severe fatigue? Has this happened to anyone else out there? ## My Insurance switched me to the generic (not my choice) about 3-4 weeks ago. Depression has been creeping in and I'm pretty concerned. Yesterday/last night was bad. Today was OK but my energy is not what it should be and my thinking/mood is not where it should be. Hoping to switch back but I don't know what is happening with the insurance...there is a $1000 penalty to go back to name brand!! ## Insurance is disgusting!! I actually feel ok depression wise and the fatigue turned out to be something else. I hope you stay stable ## Thanks. I'm glad your medication isn't th...

What is Desvenlaflax
7 Replies RSS
I've been taking Pristiq for a long time, understanding there was no generic. I've even spoken to my Dr who prescribed it about a generic not having been released. Today I changed pharmacies, having provided them with my last bottle of Pristiq for all the info. I was given Desvenlaflax, showing it was generic for Pristiq. I'm confused. I'd like to know if this is actually the generic. I'm familiar with Desvenlafaxine but never heard of what I've now been given. Also I know some generics are not as effective as the brand name. If you have any information concerning the efficacy, please provide. ## That is Desvenlafaxine, they just abbreviated it on this refill. The only way to see how it will work for you is by trying it to see. The FDA lists the typical side effe...

Extreme exhaustion with Pristiq
1 Reply RSS
This is my second try on Pristiq. The first time round, I did not feel any positive effect until four months of taking the medication (200mg). After a little over four months, I woke up one day feeling less anxious, brighter, and more positive about my future. However, with the good, came the bad: extreme exhaustion. I could barely get out of bed, barely walk, barely function. I stopped the meds because I couldn't deal with the lack of energy. I decided to try Pristiq again after a failed course of a different medication, and the same has happened again: meds seemed to "kick in" after four months, including the accompanying exhaustion. Has this happened to anyone else? Did Pristiq's effects take so long to kick in for you? Does the exhaustion go away? Any words would be ...

Starting Pristiq - what are the side effects?
2 Replies RSS
I have been prescribed 50mg of pristiq for severe anxiety. Often I've seen a common side effect on the libido. Can someone tell me how you felt, if anything? What changed? Is it permanent? Did you have any other negative side effects? ## The FDA warns that it can lower the libido, other typical side effects may include nausea, dizziness, headache, dry mouth, and mood changes. Yes, they are all reversible and not permanent. Can anyone that's taken it chime in with their experiences? ## I've deffinelty experienced the nausea, causing me to vomit and take time off work. I've noticed my mood is very mellow which I've never in my life felt!

Switched from Pristiq to Wellbutrin XL
39 Replies RSS
I'm adding a post to hopefully help someone as reading other people's posts has been very helpful/comforting to me! I have been on 50 mg of Pristiq for 5 years and I just made the transition to Wellbutrin xl at 300 mg. My doc switched me because my libido was becoming obsolete and wellbutrin is not supposed to adversely effect this. He had me start by overlapping the two meds for Week 1...Maintaining 50 mg of pristiq and adding Wellbutrin XL at 150 mg. I felt completely fine, didn't notice anything different. Week 2-I was to go up to 300 mg of Wellbutrin XL and completely stop taking the Pristiq. That didn't work. 1.5 days in I was dizzy, minor brain zap feeling (but not as intense as when i would miss a pristiq pill in the past) feeling super emotional (weepy) so much t...

Weaning off pristiq
426 Replies RSS
I just wanted to tell all of you trying to get off pristiq, its possible. I was on pristiq for severe panic attacks for 6 months. It saved my life. It gave me a chance to slow down my career, gave me a huge wakeup call. This drug put a cloud over my brain. I was not my happy, fun loving self. I was like a step ford wife. You cant wean off this pill. I was on 50mg. I did every other day for a month. Every third day for two weeks then cold turkey. It really was not so bad. I layer on my couch for three days, cried a bit and watched movies. I'm happily on all holistic medications, no longer a slave to pristiq. If I can beat anxiety, anyone can. My biggest advice.. Exercise. Next, surround yourself with positive people. Three, talk out your problems. Good luck. ## Fantastic advice and v...

pristiq stopped working
2 Replies RSS
Been on this for 2 years and was doing fine but now depressive symptoms back I can function at work but then spend weekend sleeping. I exercise 6 days a week but feel joyless ## Hello, Lola! How are you? What dose are you taking? It is normal for your body to eventually get used to any medication you take for a long period of time and for it to stop working as well for you. The time frame can vary from person to person, so there's no way to say when it will happen. The FDA lists the typical side effects of this medication as possibly including nausea, dizziness, headache, dry mouth and weight changes. Have you consulted your doctor? You may need a dosage adjustment or to try a different medication. ## I've been on pristiq for 8 months. I did improve with depression and anxiety b...

pristiq vs effexor xr
1 Reply RSS
Is pristiq 25mg equal to effexor xr 37.5mg? Will the pristiq be stronger? Insurance will not pay for effexor but will pay for pristiq. ## When it comes to these medications, it really depends on which one works best for you and the only thing you can do is try the Pristiq to see if it helps you. The FDA lists the typical side effects as possibly including nausea, dizziness, headache, mood swings, and weight changes. Have you started the Pristiq, yet?

Pristiq tapering experience
5 Replies RSS
I was on Pristiq for nearly four years to help stabilize my mood (50mg). The drug was fantastic in achieving the result I was looking for and really gave me the space in my head to come to terms with my issues and time to reflect. The side effects for me were weight gain (15kg) and loss of libido but overall a small price to pay. I decided in December to come off the drug and read as much information as I could find, both professional and user opinion. I spoke with my doctor initially and his advice was to take the medication on alternate days. I chose to ignore that advice based on the way I felt if I missed a day and reading others experiences. Against manufacturers advice I decided to cut the tablet and reduce my dose a quarter at a time. To start with I spoke with my family to make ...

Pristiq

This is NOT a good medicine. I felt more depressed on it and had several side effects, nausea, lack of appetite, dizziness, etc. Then, after being on it for 2 weeks, I had a severe allergic reaction to it. So not fun! No more Pristiq for me. Throw the stuff away! ## I went on Pristiq for 10 days - had shortness of breath, and all the other side side effects. Dr. office told me to stop 'cold turkey' - It's been 7 daysoff and I am still not feeling normal! What's up with that?? They told me it would only be a couple of days. So I call them and tell them I am still having withdrawal symptoms - they act like I am crazy! And it must be something else wrong with me! I have NEVER felt like this - until taking pristiq! When will it end? My advice - dont even start the stuff! But...
