What is Soltamox?
Soltamox blocks the actions of estrogen, a female hormone. Certain types of breast cancer require estrogen to grow.
Soltamox is used to treat some types of breast cancer in men and women. This medicine is also used to lower a woman's chance of developing breast cancer if she has a high risk (such as a family history of breast cancer).
Soltamox may also be used for purposes not listed in this medication guide.
Taking Soltamox may increase your risk of uterine cancer, stroke, or a blood clot in the lung, which can be fatal.
Do not take Soltamox if you are pregnant. It could harm the unborn baby. Avoid becoming pregnant while you are using Soltamox, and for at least 2 months after your treatment ends.
