Tamoxifen and Cymbalta and/or Trintellix
This is my 1st post and I'm basically new to the site even though I joined a few months ago. I'm very overwhelmed by the amount of posts when I search for something. This is a side issue and not a reason for my post.
So... I'm currently undergoing radiation and will begin Tamoxifen soon. I've been taking Cymbalta for years and want to switch to something else due to sexual side effects. Am considering Trintellix. I can find basically no information on the use of Trintellix and Tamoxifen on the web. What I find about Cymbalta and Tamoxifen indicates that Cymbalta has a moderate chance of causing Tamoxifen to not be effective. Is this true? What about Trintellix? My depression has been severe prior to dx for years. What in the world am I going to do?

Hi, I am having the same dilemma. I have taken Prozac for years and was told that it interferes with Tamoxifen. The Prozac has worked well for me and I was able to keep my depression at bay. I then started Zoloft when I started Tamoxifen and have been on that for a while, it is not working and I am actually weaning off it.
I finally went to a Psychiatrist who recommended Effexor. I will start taking it on Thursday this week. I really hope it works. Effexor, Celexa and Lexapro are the anti depressants that do not interfere with Tamoxifen. I am not a psychiatrist but maybe you should think about making an appointment.
Right now I feel like I am on the psychotropic rollercoaster. My husband is wondering where his kind and loving wife is. I get terribly nasty, evil and depressed when on an anti depressant that doesn't work. I could end up down that deep rabbit hole and never come back out. Good Luck, and I hope all works out well for you.
If you look at my profile, I recently posted a question similar to yours and received a lot of feedback from the helpful women on this site.

Were you ever able to find an answer? I, too, take Cymbalta. I am just diagnosed so I don't really know what to expect yet (go to surgeon tomorrow) but can't imagine not being able to take my Cymbalta or it rendering my treatment ineffective
-
I have not found an answer. The only thing I've found is. Cymbalta has moderate risk as does Trazodone which I also take. I'm fairly certain I have posted this whole thread in the wrong area, but since I'm new to this site there's not much i can do about. I've emailed both my oncologist and my psychiatrist so hopefully I'll get some answers soon.

Hi kewlmomma and Nattykat, welcome to Breastcancer.org!
As you can read in the article Treatments for Depression and Mood Changes from our main site, "Some antidepressants — including Paxil, Wellbutrin, Prozac, Cymbalta, and Zoloft — may interfere with the body's ability to convert tamoxifen into its active form, preventing you from getting the full benefit of tamoxifen." Sorry we don't really have any information on Trintellix, hope other members can help! In the meantime, if you want to know what our community members are talking about it, go to the Search function in the blue menu and type in "trintellix" (without the quotes) as your search term, so you'll see every time the word is mentioned in a post, and can then check out the thread.
Hope this helps! Best wishes,
The Mods

Hey All, I am on Trintellix with no issues and my oncologist checked to make sure it was all good to take with the Tamoxifen. I take it at bed time and the Tamoxifen in the am.
Trintellix is like Celixa, if I am remembering correctly the same company makes it.
It's also fairly new within the last 5 years I believe which could be why there is not a lot on the net about it.

Hi everyone..not sure where to post this. May I please ask those of you who have not made your stats public to do so? There seems to be a new trend not to. Also many of you are putting your information in your first post but they will not be looked at after the first page. I talked to the moderators about it but they said they could not enforce it for privacy reasons. However I don't really understand why you would be part of a community like this if you did not want to share. We all want to help but its next to impossible to answer individual questions appropriately without having the pertinent information. Hope everyone understands what I'm saying,

Hi Nattykat1968,
I am making the switch right now from Prozac to Lexapro because eventually I will be on Tamoxifen (after chemo and rads). Wanted to make the change now, before I start chemo to try and limit multiple side effects happening at same time. I think it really stinks that on top of all this we have to worry about our anti-depressants. One thing I can share - while I've been on anti-depressants for many, many years, it's only in the past few that I've actually had a psychiatrist who seems to really know what he's doing. It's been a life changer. Definitely talk to your psychiatrist and also keep your eyes open for recommendations if you don't feel like you can really rely on your current psychiatrist. (I know - like the last thing you need right now is to have to find another doctor). You are not alone! I wish you luck in your med change.

Just wanted to say how mean snd evil I was on Cymbalta not to mention the fact of having to wean off of it pretty much cold turkey. Switched to Prozac prior to breast cancer then could no longer take b/c of tamoxifen. Oncologist suggested Celexa. Took for a little while then quit working. Desperate to feel better, I finally got in with a psychiatrist who started me on Trintellex. It’s been a life changer .I’m so much better. Very weak interference with Tamoxifen. I am feeling joy and motivation to do things again. So thankful to find a dr. who finally knows what he’s doing.
-
I switched from Wellbutrin to Lexapro to go on tamoxifen. It was alright but in the end I couldn't tolerate the tamoxifen anyway. My doctor agreed to let me try toremifene (Fareston) - a different SERM in the same class as tamoxifen that has a lot of research for stage 4 and some evidence for efficacy for premenopausal women for preventing recurrence, but isn't FDA approved for that purpose in the USA.
The mechanism that makes tamoxifen less effective with certain drugs is somehow related to a genetic trait that is a lot more common in Asia. So there are a lot more Chinese studies looking at toremifene as an alternative. I also found some western articles that it should be considered a valid second choice drug for women who cannot tolerate tamoxifen, including for the reason of being on an antidepressant that interferes with it.
I was glad to go back on Wellbutrin and the toremifene is working out fine, much better side effects profile for me than tamoxifen.

Salamandra, I have been on Wellbutrin for almost 20 years, in addition to an add-on SSRI (have been on various, the one I am taking now is Viibryd) and this combination has been working for me for about 5 years. I told my MO I am not willing to go off, and thankfully, she did not push Tamoxifen for that reason. But then she told me she wants me to do OS + AI. I refused because I do not feel that my cancer diagnosis is advanced or aggressive enough to warrant such an intervention at my age. (My brain, bones and heart need their estrogen and frankly the idea of shutting down my ovaries makes me feel worse than a DMX). So then she said OK, do you want to try Toremifene, but it is hard to get and we are going to have to find it for you. I agreed to give it a try for one month after i recover from my next procedure. Have you had any trouble with insurance covering this since it is off-label for stage 1 cancer? Also curious to hear your side effects as compared to Tamoxifen.
I also currently have the issue that my Onco and pathology results on level of hormone positivity are not concordant, and I am trying to get that straightened out first before actually popping any pills. That's what my other thread was about, thanks for your response there.

Thanks for making that connection! I'm not always good at connecting user names across thread.
I haven't had any issues at all with 'finding' toremifene. My insurance requires me to use a particular mail order pharmacy (Express Scripts) for maintenance meds, and there was nothing to indicate that availability would be an issue.
My doctor did warn me that it might be a fight to get insurance to cover it because of the off label use. She said she would have that fight if necessary. But it was also not an issue. I'm not sure how much of that was due to them seeing that I had tried like four different brands and multiple doses of tamoxifen over the prior year.
Side effects wise, toremifene has been much better for me than tamoxifen. Even though all my tamoxifen side effects (except the 'sedation') went away with time or pharmaceutical help, there was still some unpleasantness along the way. (The heartburn in particular was pretty brutal for a while). My side effects with toremifene are so mild that I'm not even 100% sure they're due to the drug - I think I'm somewhat more thirsty/dizzy, somewhat more sensitive to heartburn (still taking antacids but only as needed), and that's maybe it. I can easily see staying on it for 5 years, 10 years, whatever.
It is such a huge relief. I am just getting to the bottom of my first 3 month supply of toremifene - after never having gotten there with any of the tamoxifen brands I tried - and I'm so grateful for it and that my doc let me try it.
I hope that you can get some useful medical guidance and figure out what's best for you. It sounds like a really ambiguous and confusing situation!
-
Thanks Salamandra. I use ExpressScripts too and will let my dr. know. If my insurance raises a problem I'd hope my doc could just point to the Tamoxifen interaction with other drugs I am on. Is the Toremifene available in generic? Just curious how expensive it's going to be.
I have my pathology issue supposedly sent back to the lab to try to explain any discrepancies. My MO seems kind of annoyed because she'd want to prescribe a SERM or AI to me anyway and most likely just thinks I am being difficult, but I think I am entitled to have accurate results regardless.
-
With my insurance covering it, there was no cost difference between the toremifene and the tamoxifen.
Toremifene is the generic (the brand name is Fareston).
I did look it up just in case insurance did not cover it. . I use the website GoodRx for this - it's super useful was a godsend when I didn't have prescription drug coverage.
It's horrifying how much more expensive generic toremifene is than generic tamoxifen. The cheapest price I see for a 90 supply is Walmart for $1,244! The name brand would be over $3,700! I have no idea how they get away with this, but I know our health care system is deeply broken.
If my insurance didn't cover it, I would explore ordering it from an international mail order pharmacy. There are issues with these but I'd do my research and find the most reputable seeming one (years ago I used planetdrugsdirect). I am seeing a 90 supply online for around $200. Which is still a lot. But not insane.
Edited to add: I also just found this: https://prescriptionhope.com/fareston-toremifene/ It says it brings it down to $50 per month.

It's frustrating that your doctor isn't on the same page as you on the testing.
I ended up having a lot of back and forth with my medical oncologist and there were a few times I thought about changing providers. But I kept coming back to the fact that I basically had a good impression of her as a person, felt she was smart, she was willing to engage in the conversations with me, and eventually she did agree to the things I was asking for. And changing a doctor is a crapshoot too.
Good luck!!
-
Thanks Salamandra. It's insane that the GENERIC costs that much. Since I told my MO I wouldn't be trying this until after my next surgery, I am hoping to have a several month break from her pressure and then we can re-set things. If I don't get an answer on the pathology I'm going to ask my social worker (seems to have the same role as a nurse navigator at other hospitals) to follow up.

Hi Ladies, I'm struggling with switching antidepressants and getting ready to start Hormone Blockers too. I'm switching from Celexa to Effexor and so far even after 2 1/2 weeks I am not noticing any improvement whatsoever in my depression. I'm crying every day and feel like it's getting worse. Everyone (incl Psychiatrist) says to give it time, but I would think I should be getting some relief by now. Maybe the Effexor just isn't for me??
-
hi have faith, I’ve been through a bunch of different antidepressant switches in the past. My guess is that you are tapering down the Celexa and tapering up on the Effexor, so you haven’t yet reached the therapeutic dose of Effexor yet. Even once you reach the therapeutic dose you need to give it time to build up in your system before feeling good. So try to hold out a bit. You could also ask your doc about an add on boost drug to help with your mood, there are many drugs that are used off label for this. In the interim I hope you have a therapist to help manage the depression while you’re waiting for the drugs to kick in. I’ve been where you are and am sending hugs.

Hello - I appreciate this forum. I have had a lumpectomy and reduction on both sides and am worried as the last week has been depressing. I've been on anti-depressants since college (I'm 50 now). I stopped taking my hormones right before my surgery on Aug 19th and feel weepy every day. I have no energy and don't feel like doing anything. I had to stay w/ my parents my first surgery and then after reduction, stayed w/ my sister for a week. My condo is all torn up and don't have a kitchen as their was a leak and mold mitigation was done for over a month. Don't have money to hire professionals and insurance didn't cover it so relying on my wonderful family to help. I went back to work (remotely) Friday and am worried about going back full-time. I work in HR so it's very draining, especially during COVID.
I have yet to meet w/ an oncologist for radiation. I did talk to my breast surgeon about my concerns w/ depression, hormones and having to take Tamoxifen which will make things worse. I hope I have a good oncologist. I go back to my therapist this week so am looking forward to her help.
Anyone tried natural supplements or CBD to help ease things? I have had a terrible time sleeping. My normal doctor gave me Gabapentine which sometimes helps but it takes me hours to fall asleep and take my mind off things. I try mindfulness, breathing and nothing seems to work.
My reduction has been a lot more devastating then I imagined. I am glad my margins were negative so I'm fortunate but my breasts are small and weird looking to me.
Thanks in advance!
