Estramustine is used to treat prostate cancer that has worsened or has spread to other parts of the body. Estramustine is in a class of medications called antimicrotubule agents. It works by stopping the growth and spread of cancer cells.
Estramustine comes as a capsule to take by mouth. It is usually taken with water 3 to 4 times a day at least one hour before or two hours after meals. Do not take estramustine with milk, milk products, or foods that contain large amounts of calcium. Take estramustine at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take estramustine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
