sorafenib oral Uses

This medication is used to treat kidney or liver cancer. It may also be used to treat a certain type of thyroid cancer (differentiated thyroid carcinoma). Sorafenib stops or slows the growth of cancer cells (tumors). It also works by slowing the growth of new blood vessels within the tumor.

How to use sorafenib oral

Read the Patient Information Leaflet provided by your pharmacist before you start using sorafenib and each time you get a refill. If you have any questions, consult your doctor or pharmacist.

Take this medication by mouth on an empty stomach (at least 1 hour before or 2 hours after a meal) as directed by your doctor, usually twice a day. Do not chew or crush the tablets. Swallow tablets whole with a full glass of water (8 ounces or 240 milliliters).

Take this medication exactly as prescribed. The dosage is based on your medical condition and response to therapy. You will usually take this medication continuously (without break periods) as directed by your doctor. If you have certain side effects, your doctor may adjust your dose or stop treatment for some time.

Do not increase your dose or take this medication more often without your doctor's approval. Your condition will not improve any faster, and the risk of serious side effects may be increased.

Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time(s) each day.

Since this drug can be absorbed through the skin and lungs and may harm an unborn baby, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the tablets.

sorafenib oral Precautions

Before taking sorafenib, tell your doctor or pharmacist if you are allergic to it; 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: bleeding problems, heart problems (such as heart attack, angina), high blood pressure, liver problems.

Sorafenib may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in 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 sorafenib, 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 sorafenib safely.

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.

To lower the chance of getting cut, bruised or injured, use caution with sharp objects like safety razors and nail cutters, and avoid activities such as contact sports.

If you need to have a surgical or dental procedure, tell your doctor or dentist that you are using sorafenib.

Wash your hands well to prevent the spread of infections.

Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).

Since this drug can be absorbed through the skin and lungs and may harm an unborn baby, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the tablets.
