Tamoxifen 10mg vs 20mg

Posted by jeannie53 @jeannie53, Jun 25, 2019

I was on Anastrozole for 6 months my doctor switched me to Tamoxifen because of severe muscle pain. I was given 20mg of Tamoxifen is that the regular dosage every day. It also comes in 10mg. I saw a study that women were given 5mg each day by cutting the 10mg in half and was wondering if anyone has cut their dosage so it is better tolerated.

Radiologists read mammograms and ultrasounds. Radiation Oncologists may look at them but don’t write the report. Despite knowing most of my MDs for years because I worked at hospital I have found many mercurial moods, change of tactics. When I questioned how my chest wall would be followed the surgeon said they palpate for tumors. I made a weird face and she said she would get a yearly MRI. my tumor was closer to center of chest yet my oncologist is concerned with my axillary nodes being followed but the surgeon indicated she was more concerned with the internal mammary lymph chain which is much closer to where my tumor was. I thought the surgeon was more on target so plan to ask the radiation oncologist about mammary lymph chain. It’s been unnerving to have to ask the right questions to get to what is most compelling to specific MDs.

@partI the MRI teams do write summaries, but I have to have my oncologist explain it more to me. I have had a tumor in my chest wall and the Doc has tried to shrink it with AI's (drove up my blood pressure horribly, until Labile hypertension), but the two I tried seem to have shrunk the inaccesible tumor by 2/3. Then she followed with Fulvestrant shots, but that gave me bad leg & joint pain, and finally a rash so I went off of it. They said they couldn't adjust the dose down. It may have contributed to my new swelling feet/ankles & possible venous insufficiency; still have to investigate that. So now I'm on Tamoxifen, first 10 mg, which gives me joint pain.
Anyway, I'm going to see a Proton Beam Radiologist to see if there is anything they can do to eliminate the remainder of the tumor, I think about the size of a grape. They use this on lymph chains too I've read.

Hi, I am currently cutting the 10mg of tamoxifen in half so I am taking 5mg a day. I started on Anastrazole but found out I have osteoporosis. I was then put on 20mg tamoxifen but I was too fearful of the side effects so my dr agreed to 5 mg daily or 10 mg every other day. I was initially having bad headaches but not anymore. I do get leg cramps at night sometimes, and joint pain daily which is uncomfortable . I have been on this dose for 5 months. Hope this is helpful

Hi Colleen, No I am not. I’m scared of the necrosis of the jaw side effect and also the femur fracture they can cause. I’m opting to eat calcium rich foods especially non dairy sources since I heard/ read they have estrogen and could possibly increase recurrence. I’m also taking calcium ,vitamin D3, K2 and magnesium . I drink fortified almond milk. I really hope I’m making good decisions but I’m not that confident. Thanks for asking
Mary

@marygb I recently finished 5-day radiation course & will begin soon with 10 mg of Tamoxifen daily. I'm 72 & stage 1. Hoping to protect my bones & hoping I can tolerate the 10 mg pills!

@jmab , I have ILC, stage 1, grade 2. I had a lumpectomy and 16 radiation treatments. Started Anastrazole and that made me extremely achy. I found out I had osteoporosis and was unwilling to take bone meds due to side effects. I have been on 5 mg Tamoxifen for 5 months and am tolerating it. I am 65. I can’t believe this is all they have to offer . I did read on here somewhere there’s a new medication that’s in it’s 4th clinical trial that appears more promising. Prayers, Mary

@marygb I can't believe they don't have anything better either!
Did you try the Tam 10gm?

Hi jamb, no I didn’t. I can’t stand the thought of the side effects. There have been a couple studies on the 5 mg dose that appears to be just as effective. I don’t really know if it pertains to my situation. It’s very stressful.

@marygb I agree that it's stressful! I'm 72 & I see online posts from women our age who choose not to take any meds. I'm starting 10 mg Tam next week. But if it makes me miserable, I'll definitely re-think it! Sending best wishes to you!

@jmab I am 78, and I am not taking anything. If I get a recurrence, I'll deal with it.
