Wooziness on Tamoxifen—how long might it last?

Tamoxifen can be dehydrating, so maybe take some extra electrolytes/fluids? Maybe keep a glass of salt water next to your bed and drink before you get up in the morning.

I had a bunch of early side effects on tamoxifen. Some lasted a few days (hot and cold flashes), some lasted a few months and needed drugs to help go away (acid reflux), and some never did (which is why ended up changing to a different drug).

This whole thing is super individual. People have to experiment to find the time of day or night that works for them. Some women do better with splitting the dose and doing half morning and half evening. Some stay on a 10mg dose. You can definitely try out different times and see if it helps.

Good luck!

I experienced dizziness 2-3 weeks after starting tamoxifen. I tried splitting the dosage, 10 in the morning, 10 at night. That helped the dizziness but then I had severe insomnia. I ended up reducing dosage but of course talk to your doctor first. It's been 9 months now and my body has adjusted. The sleeping is much better but I also used breathing and meditation techniques to fall back asleep if I wake up in the middle of the night and I now get roughly 7 hours even though it's a bit broken. Who knows whether it's the tamoxifen or general anxiety over this entire experience that caused the insomnia. The other side effects that I have now and didn't have prior to the medication are extreme vaginal dryness and occasional muscle/joint pains. My doctor said this can be due to general aging and/or body going into menopause and may not actually be due to the tamoxifen.

Hang in there. There are alot of threads about tamoxifen effects and it seems there's a huge variety and it seems to change over time as your body adjusts.

I took mine in the morning and at night (split dose). Did have hot flashes but found a little folding hand fan works wonders to cool me down when it was "just me" and everyone else was comfortable.
