Anyone having luck with Effexor and tamoxifen? First, has it helped your depression (if that is what you got it for, not hot flashes), and second, is it truly safe to take with tamoxifen? I have the prescription, just nervous about starting it!

    Hi, Kathy. I'm sure others will be along to reassure you. Effexor is not contraindicated with Tamoxifen. Some patients have found it very helpful. I used it years ago and it was not a good fit for me. It caused unbearable side effects, and didn't help my depression. In addition, it took a very long time for all the unwanted effects to go away - almost two years after I quit, I was still getting those "brain zaps" that you read about (it feels like little electric shocks in your head).

    But, as I said, others will have a different experience to share. It all depends on one's individual brain chemistry.

    (Exercise and acupuncture have been very helpful for my own depression.)

    I just started effexor or 1 1/2 weeks ago. I find it has helped decrease the severity and number of my hot flashes (I also had total hysterectomy in June) I have been fuzzy headed, but have not cried every day like I used to. I'm waiting to see how well it helps. I'm reserving judgment for now.

    I've been on Effexor for a little over five years now. It was prescribed for depression brought on by the cancer diagnosis and treatment. I was originally prescribed Celexa because it could be started at a therapeutic dose rather than gradually increased to a therapeutic dose, like Effexor. When I was finally able to function like myself again, I switched from Celexa to Effexor. I made the antidepressant switch because my oncologist told me we would start with Arimidex then switch to Tamoxifen after five years, or sooner if there was a recurrence. I figured the stress of changing antidepressants while dealing with a recurrence could be completely avoided by changing antidepressants ASAP.

    Effexor has worked very well for me. Over time my dosage (225mg) has been decreased to the hot-flash dose (37.5mg) per day. Side effects were minimal and the difference in my mood on Effexor was tremendous!

    Give Effexor a try. If it doesn't work alone to relieve the depression, there are other drugs that can be added to augment the effects of Effexor that do not interfere with Tamoxifen. I'm familiar with some of those drugs as well. 😉

    I've been on Effexor since Jan and now take a 37.5 dose. No major SE and I think it's helping my depression following dx tremendousl

    I too am nervous about starting Effexor. I've had the bottle for over two months now and have not tried it. My GP prescribed it as I have noticed my tolerance for stress has lessened since being on Tamoxifen and most notably, I have been grinding my teeth more than I ever have in the past.

    I suppose I'm worried that the teeth grinding will worsen with Effexor, and am also concerned when I read that some people have "brain zaps" and/or withdrawel issues when quitting Effexor. My GP thinks I'm crazy for not giving it a try and has warned me not to listen to what others say about Effexor as the low dose she's prescribed me is not in the withdrawel category.

    Any feedback on Effexor would be appreciated. I would love to hear some positive stories and this may actually encourage me to try it. On the internet, it seems to be all negative (probably why Doctors warn us not to go looking for medical advice on line...though it's hard not to as I'm sure you all know).

    I have taken effexor for over 16 years for depression. It has been a life saver for me. It does have withdrawal side effects, so you have to be very slow with dose reduction, but it does not last long. I have only had a few brain zaps. Did not even relate that to effexor. I was blaming chemo for that lovely little new side effect. Infrequent. Don't forget that decreasing your stress is an important part of treatment. I have found effexor to be life changing over the years. Hope this helps. kelly

    it is safe with tamoxifen but like Nine Twelve it did not agree with me at all. Everyone is different and I am very sensitive to anti depressants. I could feel adverse affects after just a couple of pills but kept going for 6 weeks which was a mistake. As so many find it very helpful I would say try it but let your doctor know early if you feel worse rather than better after starting it. Hopefully you will do well on it.

    I have been on Effexor for three and a half years. I have moved between doses 37 to 75 to 37 to off and back on it after a couple months because it really evens me out. After my ooph last year I went back up to 75. I have not had any trouble weaning from it. I take out five extra tiny beads every five days until I'm at the dose I want. I think I am a nicer person to be around when I'm on it. I really like it. I do keep extra pills in my purse in case I leave the house and forget my meds. I get a tad dizzy if I am a few hours late taking it. That is the only thing I dislike about it, but will manage until I'm done with tamoxifen.

    Effexor has a bad withdrawal associated with it, so staying on low doses is good. I use 10 mg's. Prozac with Gabapentin for pain and neuropathy, but both help hot flashes too. And both have withdrawals. It's what works best for you

    After beating postpartum depression and weaning off Desyrel, after 10 yrs. I’d heard that the SSRI Prozac was being used off-label for weight loss. My PCP was all in favor of prescribing it (she laughed when I told her I was depressed about my weight). It evened my mood, but didn’t control my appetite. So she switched me to the then-new Redux (which was a mirror-image molecule of the “fen” component of fen-phen without the latter’s stimulant effect), which also acted like an SSRI. Loved it, lost >20 lbs because it easily let me exercise both quantitative (appetite) and qualitative (food choices) disciplin. Then I was hit by a car, and while I was in the hospital word came down that it was being recalled due to it causing heart valve hypertrophy (which an echo proved I didn’t develop). To be safe, I was switched to Effexor, which I couldn’t tolerate--it did nothing for my depression (hey, if you were suddenly confined to a wheelchair and non-weightbearing for 10 weeks indoors, in a house with stairs, in the midst of a brutal winter, you’d be depressed too even if you weren’t already); and was so unpleasant I soon understood why it was nicknamed “side-Effexor.” I was then switched to Wellbutrin (an NDRI), which I am still on 20 yrs. later. It helps somewhat with carb cravings, but mostly keeps the demons at bay transparently. When I first found out my tumor was ER+, I thought, “oh no--tamoxifen means I can’t take Wellbutrin.” My shrink said he could try Cymbalta or Pristiq, but I should first see what my MO was going to prescribe. Turns out she put me on an AI, for which Wellbutrin is not contraindicated.

    BTW, Pristiq (desvenlafaxine) is the mirror-molecule version of Effexor (venlafaxine). Both are SNRIs. Pristiq has the fortuitous side effect of lessening hot flashes, so is often prescribed (until recently, off-label) for that.

    I sometimes get those “brain-zaps” (and have for >15 yrs) but only when I either have sinus congestion, pull an all-nighter, or get up before I’ve gotten sufficient sleep. I’ve been assured it has nothing to do with my meds.
