Hello Robbie, you will see this ' Every woman is different' when it comes to every treatment very often here. From chemo to radiation, to the AI's, Tamoxifen and healing from surgeries. Just like everyone who got the flu or covid, all different how they affected us. We would all love a simple answer with everything but there isn't any. Not only do women get side effects at different times but women also have different side effects. Some women feel them early in treatment and some not for months. Some women suffer hot flashes and fatigue, and other women might suffer pains and insomnia. It's just crazy how different we respond to these drugs. Good luck taking it, I hope it treats you well enough that you can continue taking it. 🥰

Thanks for the info. I just started 5 days ago and so far it’s been good. Wanted to know how long of a wait I would have before I started noticing side effects.

The timing of tamoxifen side effects varies for each person. Common side effects like hot flashes, fatigue, vaginal discharge, mood swings, and nausea can begin at different times after starting treatment. Some people experience multiple side effects while others may have very few or none at all.

The timing of tamoxifen side effects varies for each person. Common side effects like hot flashes, fatigue, vaginal discharge, mood swings, and nausea can begin at different times after starting treatment. Some people experience multiple side effects while others may have very few or none at all.

One thing to note is that experiencing side effects may actually be a positive sign - studies have shown that people who experience symptoms like hot flashes and joint pain have lower rates of breast cancer recurrence. However, not having side effects doesn't mean the medication isn't working. If you're experiencing difficult side effects, don't stop taking tamoxifen without consulting your cancer care team first. They can suggest ways to help manage your symptoms. Also, be aware that if you do need to take a break from tamoxifen, some side effects like fatigue may continue for weeks or months after stopping the medication.
