You will most likely be prescribed antiemetic medications prior to chemotherapy and continued after your chemotherapy to help you to prevent nausea. Take these medicines on time and exactly as prescribed by your doctor. Do not miss the dosage and complete the entire course of the medicine, even if you start feeling better. You must take ample rest following your chemotherapy session. If your nausea is too strong and not relieved with medication, try sucking on some ice chips or practice deep breathing exercises. You can also suck on a piece of candy or a clove. This may help overcome nausea. Practicing meditation is also known to help combat post-chemotherapy nausea in cancer patients.
