SIDE EFFECTS: Diarrhea, changes in taste, mouth sores, nosebleeds, tiredness, headache, dizziness, or trouble sleeping may occur. Nausea and vomiting may be severe in some patients. Your doctor may prescribe medication to prevent or relieve nausea and vomiting. Eating several small meals, not eating before treatment, or limiting activity may help lessen some of these effects. If any of these effects persist or worsen, notify your doctor or pharmacist promptly. Temporary hair loss may rarely occur. Normal hair growth should return after treatment has ended. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects.

PRECAUTIONS: Before using oxaliplatin, tell your doctor or pharmacist if you are allergic to it; or to other platinum-containing products (e.g., cisplatin, carboplatin); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. Before using this medication, tell your doctor or pharmacist your medical history, especially of: kidney problems, blood disorders, bone marrow problems, nerve disorders. Oxaliplatin may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away. The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using oxaliplatin, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death). Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using oxaliplatin safely. This drug may make you dizzy or cause vision changes. Alcohol or marijuana can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness or clear vision until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana. Do not have immunizations/vaccinations without the consent of your doctor, and avoid contact with people who have recently received oral polio vaccine or flu vaccine inhaled through the nose. Wash your hands well to prevent the spread of infections. To lower your risk of getting cut, bruised, or injured, use caution with sharp objects like razors and nail cutters, and avoid activities such as contact sports. Older adults may be more sensitive to the side effects of this drug, especially diarrhea, loss of too much body water and potassium, low white blood cell count, tiredness, fainting, and QT prolongation (see above). This medication can affect sperm production in men. Therefore, men should use a reliable form of birth control during treatment and for some time afterwards. Consult your doctor for more details. This medication is not recommended for use during pregnancy. It may harm an unborn baby. Discuss the use of reliable forms of birth control (such as condoms, birth control pills) with your doctor. It is not known if oxaliplatin passes into breast milk. Because of the possible risk to the infant, breast-feeding while using this drug is not recommended. Consult your doctor before breast-feeding.
