Vaginal bleeding a tamoxifen side effect?

Posted by 63pat @63pat, Sep 24, 2023

I have been taking Tamoxafin for 2 months. I am a 64 year old female post menapause. Last night I had a small amount of vaginal bleeding. Nothing so far today. Has this happened to anyone else.

Welcome @63pat. Vaginal discharge is a known side effect of tamoxifen. However, you said that you have vaginal bleeding. Any abnormal vaginal bleeding, bloody vaginal discharge, staining, or spotting should be investigated. It may not be anything to be alarmed about, but I would certainly mention this to your oncologist just to be sure.

Was last night the first time you saw the blood? Was it spotting?

Hello. I had vaginal bleeding when I went to 15mg of Tamoxifen. I didn't have it on 10mg. I went down to 10 and bleeding stopped. I went back up and it started. So yes, Tamoxifen can cause vaginal bleeding.
