I took Tamoxifen for 5 years and had no side effects.

I have been taking Tamoxifen since February. So far the only thing I have had to deal with is hot flashes; more often in the beginning, but still get them from time to time at night.

I have been taking Tamoxifen for 2 1/2 years and the only side effect is mild hot flashes. Since I am also menopausal, though, I might have had the hot flashes anyway.

Have been taking Tamoxifen for almost a year (I'm 44 years old). Only side effect I've noticed is mild hot flashes but those started during chemo-induced menopause so may not be associated with tamoxifen. Remember, all those horrible side effects you read about are frightening but only happen to a few people and hopefully, the benefits of Tamoxifen will outweigh the potential side effects. All the best!

Thank you all for answering and sharing your experience with me.
I will be on Herceptin until Christmas (and this is a dream drug!). I had very bad side effects from chemo, taxotere and carbo and even from neulasta. So Tam has to be better, right? I saw discussions on tam tummy, depression, and excessive appetite, etc. I better stop reading these comments. :-)

Everyone is different. From my personal experience and others I have known, the side effects from Tamoxifen are fairly mild, especially compared to everything else you've already been through. I had some water retention, but when it got bad (only a few times), I could take water pills. Hot flashes vary from person to person, just like in menopause. That was my worst side effect - I bought a tower fan for the side of the bed, and have a small fan on my office desk.

I can't help you with experiences, but we can be a support for each other as I will start taking mine tomorrow evening. In my weighing of the side effects compared to chemo.....I would much rather be taking Tamoxifen. I see you are also taking herceptin....does it concern you that there may be interactions with the 2?? I am on many other meds for other health issues and have so much worry that they will interact. Let me know what you decide and I'll let you know how I am feeling as I begin taking mine. {{hugs}}
