Switched from Pristiq to Wellbutrin XL
38 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
42 Replies RSS
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...

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...

Pristiq an Libido- Advice Needed!
8 Replies RSS
I have been taking Pristiq for about 3 years now due Anxiety attacks. After taking the drug for afew days I had the worst anxiety i'd ever had, i had horrible nightmares, nausea and bad headaches these symptoms completely disapeared by about a month after starting it. After the first month life was great I was back to my normal self, I could eat food again (which was the main reason for my anxiety attacks). For about 2 years it worked great for me with minimal side effects mainly brain ticks if i took the pristiq too late in the day, If i completely forgot the tablet I would be bed ridden the entire next day with terrible brain ticks, headaches and nausea, although 99 percent of the time I felt fine. I fell pregnant with my now 9 month old baby girl and decided to stay on pristiq wh...

Weight gain on Pristiq??
553 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.

Switching from zoloft to pristiq
1 Reply RSS
After 6 yrs on zoloft it no longer helps much. I felt great for 2-3 years but know it time for a change. I had a genetic test done and my doctor decided to try me on pristiq. Reduced zoloft to 50 mg and started 50mg prestiq today. Then keep reducing zoloft. Anyways I'm freaking out about being on 2 antidepressant at the same time (serotonin syndrome) and am also scared of withdrawal symptoms from the zoloft. Is there anybody who's had a positive experience switching from ssri to snri?? ## Doing a gradual change by tapering up and down is normal, as long as your doctor is monitoring you to keep an eye out for any possible problems. It should also eliminate the worst of any withdrawal symptoms, though you may still experience some nausea, diarrhea, and anxiety, according to the NI...
