Does Tamoxifen Cause Swelling and Water Retention?

I was on it for 30 days before starting chemotherapy. I had no problems with swelling, but I think I was retaining some water. I am on a mild diuretic for blood pressure control. I also control my sodium intake and drink lots of water.

Water retention and swelling can be concerning side effects that some people experience with tamoxifen, and it's completely understandable to want to know what options might help. This is definitely something worth discussing with your oncology team, as they can evaluate whether these symptoms are related to your medication and suggest appropriate management strategies that work best with your specific treatment plan.
