It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly. Blood tests may be needed to check for unwanted effects.

Women who are pregnant or may become pregnant should not use bicalutamide tablets. Using this medicine while you are pregnant can harm your unborn baby. It may also cause birth defects if the father is using it when his sexual partner becomes pregnant. Male patients who have female partners should use effective birth control during treatment with this medicine and for 130 days after the last dose. If you think your female partner has become pregnant while using this medicine, tell your doctor right away.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.
