Tamoxifen Oral

If you want to treat or prevent
 breast cancer, you may benefit from tamoxifen citrate (Nolvadex®). This prescription medication works by binding to estrogen receptors in the breast, reducing the effects of estrogen. By decreasing these effects of estrogen, the drug can help decrease the growth of breast cancer.
 
As an oral medication, tamoxifen comes in the form of a tablet or liquid, and is typically taken once or twice a day. Your dosage amount will depend on several factors, such as the severity of your breast cancer, other medications you are taking, and whether you are using tamoxifen to treat or to prevent breast cancer.
 
Although most people tolerate this medication well, it is not suitable for everyone. Possible side effects include nausea, hot flashes, and fluid retention.
