Cisplatin is a chemotherapy medication commonly used to treat various types of cancer, including testicular, ovarian, and bladder cancers. It works by interfering with the DNA in cancer cells, preventing them from dividing and growing. This helps to slow down or stop the spread of the disease. Cisplatin is usually administered through an intravenous (IV) infusion in a hospital or clinic setting. While it can be effective, it may also cause side effects such as nausea, vomiting, and kidney damage. Doctors monitor patients closely to manage these potential issues during treatment.
