Effexor and Weight Loss/Gain

Has anyone taken Effexor and, if so, did you experience any weight related side-effects.  

I am worried about gaining weight and will not take this medicine until I find out.   I'm just scared because SSRIs cause gain.  Even though this is not an SSRI, it could cause weight gain.

Hi there, I know this question was asked a few years ago, not sure if people are still active on here?  I did want to chime in on my experience so far on Effexor and losing weight.
I've been on Effexor for 2 months and have lost 20 pounds.  Part of it is loss of appetite, it feels like an appetite suppressant to me.  And I'm also wired and awake most of the time, so I am in constant motion, I go to the gym 4 times a week, walk 1 hour a day just to burn off some pent up energy!.  BUTTTTTTTT, there is a HUGE BUT here, I haven't had a solid sleep since I started.  I'm suffering insomnia big time.  A good night is 4 hours sleep with 2 different prescription sleeping pills :(  A bad night sleep is NO sleep.  I take Effexor mainly for anxiety, so my anxiety is the absolute worst at night with tossing and turning and my eyes wide open.  For example it's 7:30am and I have not slept in 24 hours......sooo, weight loss or sleep?  So tired of all these meds.  Dunno if this post helped anyone or made it worse.    PS.  I am 41 and was in need of a 40 pound weight loss, so I haven't hit the underweight categorie, luckily I have plenty of extra padding to part with :) I would be terrified of this weight loss if i was of a healthy weight to begin with.  I'm also on Effexor for mild depression and the depression is gone, but anxiety is upped at night.  
I think different people just respond differently to different meds.  I was on Seroquel and gained 20 pounds in one month.  Horrible drug.

I have been on 250 mg of Effexor for a year with no weight side effects. Everyone is different, but you should give it a try if you are depressed. It started working within a week for me.  English

I was on Effexor and I gained about 5 lb. then I went got the depo shot shortly after due to the server birth defects Effexor can cause. I have now put on around a totally if 18lbs. I am in fitness and eat health a vegetarian diets with some shrimp for protuberance when I go into heavy weight training. I have been off the depo now for 16. 16 weeks after my last shot. I do not know if the Effexor had a larger part in contributing to the weight other than the 5 lbs or how much depo did. But I dislike them both and would never ever take either again. I have been off the Effexor for two days. I also had sever admins rectal bleeding. Which can be a side effect of Effexor. I am pretty miserable right now fighting to get my fit body back and the serve depression that has come along with the gaining of so much weight so uncontrollably.

Effexor is the worst med EVER. trust me 34 been guinea pigged on these meds for 20 years, new med, raise dose, add booster, raise, then change... over n over. Effexor kept me from getting pregnant for 2 YEARS, no birth control was taken. I did not think I could get pregnant. After a month in jail, no meds, worse withdrawals of my life, and it all left my system, very shortly after, I was pregnant. Side note..I was so suicidal at one point on effexor I ate maybe 2 bottles 300mg pills, to overdose. Legs went first, couldnt move em. Also note withdrawals set in upon only missing 2 or so days. STAY AWAY FROM EFFEXOR.,!!! SIMILAR SIDE EFFECTS FROM CELEXA ALSO.

Hi everyone.

I am suffering from panic dissorders and light (let's say) depression since 1997 (17 years-old) when was the last year to school and I had to study hard so I can write exams and go to a university. I was trying to cope with it with psychotherapy only, having my ups and downs (mostly downs) and never thought of taking drugs. Actually, in my mind, taking psycho drugs was a proof for me that I had a serious problem and I was trying to avoid them with any cost.

However, on 2004, before starting my last year in the university, my panic dissorders were so strong that I couldn't go anywhere or stay alone (I was afraid that something will happen to me and I wouldn't have someone near to help me) and dippression begun to show its face very quicly.  I'm 1.74 tall and on 2004 I was weighting 67 - 69 kilos having nice muscles and exercising fairly often. During this month of deppresion, I lost about 7 kilos (so I was weighting 60 kilos), basicaly because I was afraid that If I eat, I will vomit, although this never happened.

My doctor gave me Seroxat 10mg and Centrac 10mg, each for every day and night. The panic attacks gone but  my phobia to be alone anywhere was still there. I begun eating better and I gain 15 kilos within a year. My phobia gone also. I managed to take 2 BScs on Computer Science. On summer 2006 I was weighting 78 kilos, no depression, no phobias. I managed to loose 8 kilos until summer 2007. On September 2007, when I begun my MSc, I got very stressful and dipression came back again. I switched my MSc from full time to part time, I continued with the same drugs and doses, I never stopped psychotherapy (changed 2-3 therapists). The psychoterapist I was visiting back then told me to stop Seroxat and contine with the same dose of Centrac. How can I discribe the months coming... Nightmare! Depression, anorexia, crying all day, my mood was down all day long etc. I lost 12 kilos in 9 months.

I switched to another psychotherapist who gave me Seroxat 10mg again. In about 3 months I was much better but I didn't gain any weight. I was good. I was weighting 66 kilos and it was perfect. My libito was very high, no stress for anything.

I continued the same drugs and doses until a couple of months ago. From summer 2010 to summer 2013, I lost 4 kilos very grantualy. When I broke up with my girlfriend after 11 years on 2013 after, I lost 4 more kilos so in summers 2013-2014 I was weghting 58 kilos, the minimum I had ever "achieved" in my life although I was taking the drugs and doing psychotherapy.

Since then, I never managed to take any weight.

On December 2015, the company I was working for the last 6 years closed so I have been unmployeed until today.
From December 2015 until today, I weight 54 kilos. In other words, I am skinny.

So, I went to my doctor and he proposed to double Seroxat's dose from 10mg to 20mg every aday and night and subtitude Centrac with Clonotril 2. Things gone a little bit better but during summer, everyone gone for vacations, I had no money to follow, I was feeling so alone. So, crying came back, interviews were stressing me so much etc.

To the psychiatrist again...

He proposed me to go from Seroxat to Effexol. Begining with 75mg (morning and night) for 15 days and then go to 150 mg in the morning and 75mg at night. I have begun this therapy a couple of weeks ago and looks fairly good. No notable side effects. Sleepy, yes, but just this.
However, yesterday I got the 150mg in the morning and... That's it! I was so sleepy that I could got up my bed all day. I ate nothing all day. Just sleeping.

Now, I am a little bit affraid. Should I continue this 150mg in the morning; Will this sleepy feeling gone sometime soon (in the next 10-15 days, maybe)? Should I continue with 75mg in the morning and night? When will I see if the drug affects my depression? How long it will take to gain some weight?

Also, I read many posts from people who face sexual side effects. OK, my libido is low but does this happens because of Effexol or because of my depression? When should I worry about this issue?

The last thing I want to share with you is this: every single period of my life, since 1997, when I was feeling good, strong, happy was in conjuction with my social daily life and my stress levels. When this part of my life was bad or my stress was high, I was depressed even I was taking double doses. Drugs is a supplement for a better life. The main job should be done by us... I am writing this here so I can eventually understand it. But, after 20 years of different kinds of psychotherapy and psychoanalysis, being 36 today, I haven't managed to find a working solution for a better life in contrast with the majority who find their mental piece quickly and painless.

Circumstancial depression. Season disorder. I have similar experience. I only take nerve pills as needed. I medicate myself better than any diploma waving therapist. I also have 3 years college psychology. Anyway. I can't get help. I help myself. Watever it takes to stay alive and maintain, cope, be happy, sad ect. I'm not a zombie. I feel, we go the stages as to grow emotionally, mentally ect. Good luck. Best bet might be welbutrin. Most of these psyc meds DO DECREASE LIBIDO. Good luck. Love and LIVE. SURVIVE. TRUST ME, THE HEAD SHRINKER BEHIND THE DESK DOESN'T CARE, ONLY SEES DOLLAR SIGNS ECT. THE MAN BEHIND THE DESK CAN'T FIX U IN THE WAY THAT U CAN FIX YOURSELF AND BECOME A COMPLETE WHOLE FUNCTIONING FEELING HUMAN BEING. KNOW YOURSELF. XO

Effexor now is being directly associated with anorexia (not to be confused with the eating disorder anorexia nervosa). This form of anorexia is caused by a loss or decrease in appetite and is one of the most common side effects of taking Effexor.Nov 22, 2010

I am approaching the four week mark since going off effexor. It has been pure hell to sum it all up. I am also experiencing horrific weight gain. I have noticed that I am retaining fluid which I know is contributing. I do not understand the weight gain. Eating has been a challenge due due to the relentless nausea. Still searching for answers. Obviously, my body is completely out of whack. Will my metabolism return to normal in time? Will the weight gain reverse itself? If anyone as the answer, I would sure like to know.

I am sixteen years old. I started Effexor about a month ago. I since then lost all my appetite. I am down to eating about less than one meal a day. I have lost 4.5 lbs so far, and I see that trend continuing. I can't force myself to eat either because the thought of it makes me nauseous. I was put on this for major depressive disorder.

marissa_isabell: I'm so sorry that U R struggling w/ major depression, esp at such an early age. I hope the effexor is helping. I started w/ serious suicide attempts at around 20, and put my family thru hell while I was in coma after coma, but I never took any anti-depressants, so.... maybe that's why.  As I aged, my depression decreased. Now that I'm REALLY OLD, and sick, it's returned, but I don't think it would have if I weren't so sick. I wish you well.

   VENTING: I was roughly 110-120lbs before I went on Effexor.  6 months later, I stepped on a scale, (still in my slightly tighter "small" sized clothes) and I weighed 170.  TRUE STORY.  I fit more comfortably in a medium now and have gone up roughly ONLY 1-2 sizes in clothes.  My BP is normal and pulse is only slightly elevated (probably due to caffeine consumption) This situation is blowing everyone's (including my doctors') mind.  What did this medicine do to me?
    I have had one hell of a time getting off this antidepressant.  Its taken me a month to step down to the 30-ish,grms dosage.  I have had horrible withdraw.  The brain zaps drive me nuts, but I think I'm going to flush the rest of them and let the rest ride out.  My job doesn't allow the weight gain.  Period, end of sentence.
    Reading this thread calmed my fears that I acquired cancer.  Someone mentioned to me that people with MS often have severe reactions to medications, (my aunt has MS) and I'm beginning to wonder if this is the root of the problem...
    No one really knows how my situation is really even possible. Anyone have any advice (other than ditch the med and start running lol)? ...Possible serious health situations that could have caused this?

ANY info would be great...

You are so lucky you are dropping the weight right away. I expected hat to happen but I actually gained.  I'm afraid I still will and I'm on Nutrisystem.  It seems as though no medical professionals will weigh in on this and tell us how to lose the weight.  They won't even admit it is from this lousy class of medicines.  I am so sorry I took it even though it did help (because now I'm off and that will change) but the weight just kept going up and up and up and I already gained 15 pounds and don't want to gain more.  My thighs and hips are huge and I can't wear any of my clothes…though some things still fit around the waist…because the gain in all in the hip and thigh and stomach area.  It is totally disguising and I am so ticked off that they didn't tell me this would happen. I would have NEVER taken it…NEVER!  Now I wonder if I can EVERy lose this lousy weight.

I feel for you as i am going through the same thing. My Dr. says that Effexor does not cause wait gain. I have been doing what you have been doing on my own for about 2 weeks now. I'm happy to say that I've lost 4lbs with no change in food or movement. The zaps, did you get them in your neck? while on the Effexor too? I do and it is so annoying!

I am glad I found this forum. I absolutely never post anything online, however I want to share my experience too. I started taking Effexor in February of 2015 after experiencing extreme depression despite 300 mg of Luvox. At the time I was in a half way house and prescribed 75 mg. I left the house soon after and found that my mood improved...but only slightly. At this point I had gained significant weight but attributed it to 30 days in rehab then transition to halfway house. I gained roughly 10 lbs. I have struggled with an eating disorder for most of my life and weight gain is a huge source of anxiety. I struggle with bulimia. Before taking effexor my eating disordered symptoms were out of control and taking a huge toll on my body and mind. I was binging and purging constantly and obsessing about food and weight. After returning home from the halfway house I saw slight improvement and my psychiatrist upped the dosage of effexor to 150mg. Gradually with some changes I began to see improvement. My mood was great and my obsession with food and weight diminished. I saw huge improvement in my level of anxiety and even stopped using eating disordered symptoms as frequently without any outside support. Things all and all seemed really wonderful...but i continued to gain weight, despite eating more healthfully and "normally" than perhaps ever in my life. I made the difficult decision to taper off the effexor in fear that the weight gain wouldn't stop and that my great mood would forever be plagued by underlying anxieties about weight. I cut the dosage in half for one week (150 to 75) then in half again for two (75 to 37.5) I am now taking 37.5 every other day (even though this seems silly and like a poor strategy..my psychiatrist recommended it...so im doing it because i am in a vulnerable position forced to trust a doc with my delicate emotional balance...grr). I am beginning to see real emotional side effects. I am exhausted, struggling with body aches, and noticing irrational fears and anxieties returning.I notice intense mood swings, anger and agitation. Sex drive is gone (wonderful to see it return when taking 150mg) and I find my boyfriend's presence annoying. I have also begun binging and purging again with frequency. (also no weight loss yet) I am left feeling angry and taken advantage of. I am a young woman who has been forced to trust so many doctors. I am lucky to have the support of family to help me through these times, but I fear for all of us, struggling to make informed decisions when plagued by serious mental illness. I am saddened that I feel my survival is dictated by medication. I offer my love and support to those who continue to struggle as I do. None of these are easy decisions and I wish the psychiatric community would acknowledge the complexity of our situations. Am I really deciding between Fat and Happy? I don't think it's that simple.

If possible, can you update on your situation regarding weight gain and Effexor? I just read your post, which I know is outdated, but you are the closest to describing my own circumstances and I need to make some type of change.  Thanks!

are you sure your issue is metabolism related?

I thought mine was the same, and no doubt metabolism was effected in ways while on the drug, but a month after starting effexor I developed a swollen abdomen, it could be from a hypersensitive gut causing bloating, fluid in the abdomen, abdominal wall/diaphragm not contracting/relaxing as they should, there is a plethora of things it could be. what I am sure of, is that effexor is the cause. I also have a lot of subcutaneous water under the skin from the effexor, which shouldn't be confused with fat. all of this after being off the drug over three months now and no improvement in symptoms

Try Himalayan Pink sea salt for edema, I use it to help balance my electrolytes and it works quite well.Sprout's carries it.  I've been on generic effexor since suicide attempt 2 yrs ago. I just saw my doc today, told him last week I was making plans to kill myself but cancelled b/c of my son, told him I didn't think effexor was helping. I'm on 75 mg 3xday. He told me to INCREASE it to 150mg 2xday! This may help me temporarily, but I can';t keep going up on dose forever! I've gained some weight but only b/c I rarely leave the house and spend all day in bed w/ blinds closed. Wish I were dead.

I believe that what the studies show is that it initially can cause weight loss and then gradually over time will slow the metabolism. I'm the same - on it for 10 years and I'm quite sure it caused my insulin resistance. I am now weaning off because pregnant.
I'm pregnant and losing weight!

Hello!

I lost 25 pounds on it immediately.  I guess I was eating and feeling depressed because of my weight.  My doctor told me that it just depends on what people do in depression...some eat and some don't.  Now that I'm coming down off the meds (from 325mg to 75mg) after 3 years, I actually gained 15 pounds!

It just depends on you.  I actually want to go back and increase my dosage because I think I've been stress eating and my anxiety has manifested in memory loss.  

Hope this helps?

I was on Effexor for 4 years.  I'm a female, 49 years old.  I gained 40 lbs from it.  I thought it was because of all the stress in my life....NOPE!  In August 2014, I started weening myself off it.  I decreased my dose each week for 8 weeks.  I've been completely off all medications for 4 weeks now.  I'm walking daily and watching my calorie intake.  ( I always have....I eat around 1500 calories a day and switch up my activities).  So far, the scale is the same.  Can anyone who's LOST weight AFTER going off effexor, tell me how long it took?  When did your metabolism start to work again and did you ever get back to your pre effoxor weight? Thanks! :)

I lived in Wa and I know how you feel with the weather.  I just started taking venlafaxine hcl er and have gained 12 lbs in 4 weeks. I am not eating any different than I was 8 months before I started and had lost 22 lbs. I just left a message for my dr on her recorder because it is Sat and I want off of it.  I was on Prozac for years and NEVER had one side effect not one. Dr put me on this cause she said I had been on Prozac to long for it to be effective.  Worse thing I could have done. I have blurred vision, headaches, and feel very weird in my brain and body, get dizzy and even feel faint when I stand up.  I still ten to still cry once in a while even on this.  I'm sorry I had been trying to loose weight before this and was doing great.  Slow and healthy the right way.  I've felt a little out of breath everyonce in awhile and have heart palpatations.  I just felt like I was heavier so got new scales and saw I had gained the 12 lbs and said hell no the side effects and gaining weight NO WAY.  I was on 150 and had really bad stomach cramps on that amount and was always having problems with my bowls. So she put me on 75 and told me to take the 75 for 5 or 6 days then try to go back on the 150 for a few days then back on the 75 to see if that helps. Well guess what it has not made a difference at all except the stomach cramps and the bowl problems are better on the 75.
Good luck with you and everyone else using this stuff.  I am going off as soon as I see her Monday. Hope I do not have bad side effects for goin off of it.  I already about a year ago thought of sucide.
