Medications for chemotherapy side effects are used to manage nausea and vomiting, low blood cell counts, and mouth sores. They also help protect damage to the kidneys, hearing, and bladder caused by certain chemotherapy medications. Antiemetics like Emend (aprepitant, fosaprepitant) are available in oral and injectable forms. Chemoprotective agents, such as amifostine (Ethyol), are typically given as injections. Cell growth factors like Ryzneuta (efbemalenograstim-alfa) are also administered as injections.
