Switching from pristiq to generic pristiq
64 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...

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...

What is Desvenlaflax
10 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...

Pristiq causing episodes of anger
2 Replies RSS
I was on 50mg Pristiq and didn't realise I was having anger issues on days I forgot to take it. I was only on it due to injuries stopping me from working and suffering from pain and financial issues. It broke up my relationship. After the break up I went up to 100mg. After some months I started to space out/blackout in the afternoon on days I forgot to take it. I always took it at 7am. Well my partner and I had gotten back together and it happened a couple of times in the 4 or 5 weeks we were back together. The 3rd time was the only time I had alcohol the day I'd forgotten to take the Pristiq and I had a violent episode. My life is in ruin and no one is listening. They think I was just drunk. Violence was not normal behaviour for me but drinking half a bottle of bourbon was. I o...

Pristiq started making? me dizzy and sick
Post a Reply
I started on Lexapro 5mg then quickly to 10mg for derealization/depersonalisation depression about 15 months ago. It wore off really fast and my doctor put me on Pristiq. It didn't really hit the spot straight away but over time I felt back to my normal self. I started getting more frequent brain fog and upped the dose until I was on 200mg a day but after a while any amount of Pristiq made me fatigued dizzy and it got worse until I'd get more brain fog, extreme fatigue, dizzy, nausea, sweats and vomit. I've gone cold turkey for 2 day's now. No brain fog at all now but still dizzy and extremely fatigued constantly. I'm wondering if I have some type of vertigo like pseudo vertigo or pseudo cushings syndrome. They seem to be the only things I can find that possibly tick th

pristiq stopped working

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...

Weight gain on Pristiq??
555 Replies RSS
I have been on Pristiq now since November of 2008...not quite 5 months...and I have put on 15 lbs since starting it. DESPITE working out with a trainer at the gym twice a week weight training, 3 days a week of cardio AND counting calories. My doc assured me that I would also have a decreased appetite on Pristiq, which I have yet to find true...so he has now increased my dosage to 400 mg. Does anyone have anything to add to this?? I'm just frustrated! ## i was switched to pristiq a few months ago and just recently wellbutrin was added - i take 1 of each pill per day - it has done nothing to me in gaining weight - i am continuously losing but i have some emtional things going on right now which i believe the weight loss is contributed too - unfortunately i have run into many that have...

atrial fibrillation ## Pristiq, which contains the active ingredient Desvenlafaxine, is an antidepressant. Some of the most common side effects include: nausea, drowsiness, sexual dysfunction and constipation. ## For 18 years I have been taking Prozac. Each time I have attempted to change, under the care of a physician, I've touched the bottom of depression again. During the last several years my dosage has been upped to 40 mg in the AM and 40 in the PM. I've suffered anxiety, expecially upon awakening in the morning. In the last 10 years I've been divorced from a man with passive-aggressive tendancies. I go to a well reputed psychologist,exercise and eat well. I regularly meditate and do daily journaling,etc. I'm now married to a good person. My psychologist, chiropract...

Extreme exhaustion with Pristiq
2 Replies 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 ...

Weaning off pristiq
427 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...
