This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

Read the Patient Information Leaflet if available from your health care professional before you receive oxaliplatin.

This medication is usually given by infusion into a vein over at least 2 hours by a health care professional. It is usually given every 2 weeks along with other medications (such as 5-fluorouracil and leucovorin). The dosage is based on your medical condition, body size, and response to treatment.

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 last or get worse, tell your doctor or pharmacist promptly.

Temporary hair loss may rarely occur. Normal hair growth should return after treatment has ended.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Before using oxaliplatin, tell your doctor or pharmacist if you are allergic to it; or to other platinum-containing products (such as cisplatin, carboplatin); or if you have any other allergies.

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 (cannabis) 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 (cannabis).

Tell your health care professional that you are using oxaliplatin before having any immunizations/vaccinations. Avoid contact with people who have recently received live vaccines (such as flu vaccine inhaled through the nose).

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

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, dehydration, low white blood cell count, tiredness, fainting, and QT prolongation (see above).
