Nolvadex (tamoxifen) is a potent prescription drug intended for the treatment of cancer. It efficiently deals with the disease that has spread to other parts of the body and helps patients with a high risk of developing the disease to reduce the likelihood of getting cancer, helping in more than 40% of such cases. Take this drug exactly as prescribed, at the same time every day, and try not to miss doses. The best way you can make sure you take every dose is to do it at the same time every day. Taking Nolvadex is associated with a higher risk of developing serious and sometimes fatal health conditions, such as blood clots in the lungs, a stroke or cancer of the uterus.
