Weight gain is not listed as a side effect, however changes in appetite or weight is listed:
Two aspects; depending on your metabolism, it can either increase your appetite therefore the weight gain or the contrary depending on how you organism reacts to Effexor.
Remember they are possible side effects, maybe you will experience them or maybe you will not.
In my case I take my fair share of medications, all of them have one thing in common as a possible side effect: increased appetite=weight gain, I am 44 male and have never experienced weight gain.
Effexor Side Effects
Metabolic side effects have included weight loss (3%).
A recent short-term study (6 weeks) has reported an average weight loss of 2 to 3 pounds in patients treated with venlafaxine.
The drug manufacturer will not admit there is weight gain with this drug, but I have read so much that people gain weight.
I know it does increase my appetite, and I find myself eating a lot of carbohydrates, which of course, makes me gain weight.
There may be a medical reason. I have googled this subject, and metabolism does seem to come into it. Some people gain on Effexor, others don't. I feel, however, that most people on Effexor are unhappy about their weight gain. I find it takes a lot of willpower to eat sensibly. That is the answer.
With this medication it slows down ur metabolism which is why you gain weight on the medication
I too find I crave carbs. I have always liked sweets, but this is more a drive for it. I don't have an increased appetite, I just eat the wrong things. I have a heck of a time with my weight, however I always had to watch it, so how much is me and how much is the effexor I can't say.
Effexor has made me gain weight but I don't have cravings for sweets. I'm very limited to carb intake bc I'm allergic to grains.
I talked to my Dr about my weight and he agreed that it's the Effexor.
My problem is that I can't go back to having anxiety. Effexor is a nightmare to get off so I'm feeling trapped
I don't really believe that weight gain from this antidepressant is attributed to increase in appetite, nor do I believe this for any antidepressant. There is likely some medical reason behind it.
When I went on lexapro, I weighed around 120 lbs and gained almost 40 pounds within 4 months of taking it, despite my appetite/food intake remaining the same. As soon as I went off of it, the weight poured off of me. Then, I started Effexor XR and, once again, did not change my eating habits and went from around 140-180 in a little under a year. This past summer, my husband and I went to the gym on a daily basis and ate very healthy for three months and all I lost was 2 pounds when I should've lost around 20. I'm now down to my final Effexor pill, which I'm tapering from currently, and the weight gain from this medicine has devastated me.
Not to mention since I've been taking it, my eyesight went from 20/20 to "you need glasses" at the DMV, my skin has gotten terrible, and my menstrual cycle is very irregular. I don't think this is a healthy medication at all. I'd rather suffer with the anxiety/withdrawal symptoms than ever take this medication again. My neurologist, who put me on the medicine, swore up and down that it wouldn't cause weight gain or any other serious side effects but, like my other doctor, he was wrong. This medication literally ruined 2 years of my life when it should have improved my well-being. Never again.
I've been on effexor for several years. While I do agree it helps, first its not hard to quit, just ween ur self off in a month, month & an a half. For the ppl who gain weight. That makes ur blood pressure Go way up, so do ur selves a favor and walk around the block a few times. I'd hate to see someone on effexor die of heart disease.
