These side effects occur about as commonly as after orchiectomy. Side effects of antiandrogens in patients already treated by orchiectomy or with LHRH agonists are usually not serious or common, but may include nausea, diarrhea, and tiredness. The side effects of chemotherapy depend on the type of drugs, the amount taken, and the length of treatment. Temporary side effects might include nausea and vomiting, loss of appetite, loss of hair, and mouth sores. Because chemotherapy can damage the blood-producing cells of the bone marrow, patients may have low blood cell counts.
Most side effects disappear once treatment is stopped.
There are remedies for many of the temporary side effects of chemotherapy. For example, antiemetic drugs can be given to prevent or reduce nausea and vomiting.
