how long does tamoxifen stay in your system after you stop taking it

Good question! Anyone out there know? I would think that it depends on your body chemistry, your dosage, age, metabolic rate (slow/fast/sluggish), and health. Ask your doctor - and then share the answer with us, please.

I have that same question.
I read that it can be up to 6 weeks to leave your system.
I had to stop my tamoxifen after just a year due to WEEKLy yeast infections! I have been off 2 months and still having hot flashes. I had one cycle last month. I am 48 years young so am wondering if it's menopause. I would appreciate any other insight as well.

I was told by my oncologist that it keeps working in your body for five years. I am due to come off meds in November. It will be five years. Two years on Aridimex and then Tamoxifen. His receptionist who is also on Tamoxifen said they are now recommending you stay on it for life. Seeing as I've had no life in the last 4 years and a bit, I am finishing. I get stining in my left breast, but my breast surgeons said stinging is not a symptom of breast cancer. I trust him.

I had been taking Tamoxifen for almost 3 and a half years as a breast cancer preventative. I had a full hysterectomy after one year on the medication. Last Spring I started having some weird symptoms (racing heart, shakiness). I was told to keep taking the meds. I decided to stop the meds this December 2009 after too many days of feeling out of it. I initially felt much better, but still have some days that feel like I did when I was on the meds. How long does it take for the Tamoxifen to leave your system? Has anyone had the same side effects that I have had? I take no other medications, except a multi-vitamin and calcium+D supplement. I know Tamoxifen is a chemotherapy type drug, but I have no idea the length of time it remains in your system. Any thoughts would be most appreciated. I have discussed this with my breast surgeon and oncologist and have not really received any substantial information from them. I am scheduled to see a cardiologist for the racing heartbeat, but my gut is telling me that the Tamoxifen still might be the cause.
