Having a TLH/BSO but on tamoxifen. I know I stop the tamoxifen prior to surgery, how soon? Surgeon says ask onc onc says ask surgeon. Do I stop Lipitor (atorvastatin)?

Stop both 1wk preop: I assume that the rationale for tamoxifen and the hyst BSO are for metastatic breast Ca. If the oophorectomy controls the disease the tamoxifen should not be used in order to evaluate the effect of castration on disease. Lipitor (atorvastatin) can ne restarted when post op diet is resumed. Hormone ablation best used for ER+ disease and not triple neg problems. ...Read more

I'm having hot flashes when taking tamoxifen. Is there anything I can do?

I'm having hot flashes when taking tamoxifen. Is there anything I can do?

Yes: Tamoxifen interferes with estrogen action causing hot flashes. Taking estrogen to control hot flashes would defeat the primary reason to take tamoxifen so that is not an option. Some women with hot flashes are helped by taking some antidepressants (ssri). Another option is to try clonidine, a blood pressure medication. Non of these are 100% effective, but some women definitely benefit from them. ...Read more
