Do not breast feed during treatment. This risk is small when compared to an increased protection against breast cancer. Tell doctors or dentists that you are being treated with tamoxifen before you receive any treatment from them. Tamoxifen is usually well tolerated and serious side effects are rare. This should improve as your body adjusts to the tamoxifen.
Most people have little or no nausea.
This usually improves as your body adjusts to the tamoxifen. Take your tamoxifen at bedtime. If night sweats interfere with sleep, try taking your tamoxifen in the morning. Bone pain or swelling and redness at the site of your cancer can sometimes occur when you first start taking tamoxifen. This should go away in a few days as your body adjusts to the tamoxifen.
