Uses for gemcitabine

Gemcitabine injection is used together with other medicines (eg, carboplatin) to treat patients with advanced ovarian cancer that has come back at least 6 months after treatment with other cancer medicines (platinum-based).

Gemcitabine injection is also used together with other medicines (eg, paclitaxel) to treat metastatic (cancer that has spread) breast cancer in patients who have received other treatments (eg, anthracycline medicine) that did not work well.

It is also used together with other medicines (eg, cisplatin) to treat non-small cell lung cancer that has advanced, spread, or cannot be treated with surgery.

Gemcitabine injection is also used to treat pancreas cancer that has advanced or spread to the other parts of the body in patients who have been previously treated with fluorouracil.

Gemcitabine interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal cells may also be affected by the medicine, other effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects, like hair loss, may not be serious but may cause concern. Some effects may occur after treatment with gemcitabine has been stopped.

This medicine is to be given only by or under the direct supervision of your doctor.

Before using gemcitabine

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of gemcitabine injection in the pediatric population. However, because of this medication's toxicity, it should be used with caution, after less toxic alternatives have been considered or found ineffective. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of gemcitabine injection in the elderly. However, elderly women patients are more sensitive to the effects of this medicine than younger adults.

Breast Feeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Gemcitabine often causes nausea and vomiting. It can also cause flu-like symptoms such as chills, fever, general feeling of illness, headache, muscle pain, and weakness. It is very important that you continue to receive the medicine even if it makes you feel ill. Ask your doctor or pharmacist for ways to lessen these effects.

Precautions while using gemcitabine

It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly. Blood and urine tests will be needed to check for unwanted effects.

Receiving this medicine while you are pregnant can harm your unborn baby. It may also cause birth defects if the father is receiving it when his sexual partner becomes pregnant. Female patients should use effective birth control during treatment with this medicine and for at least 6 months after the last dose. Male patients who have female partners should use effective birth control during treatment with this medicine and for at least 3 months after the last dose. If you think you have become pregnant while receiving this medicine, tell your doctor right away.

Gemcitabine can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are needed for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:

This medicine may cause lung problems (eg, interstitial pneumonitis, pulmonary fibrosis, pulmonary edema, adult respiratory distress syndrome), which can be life-threatening and require immediate medical attention. Check with your doctor right away if you have new or worsening cough, fever, chest tightness, or trouble breathing.

This medicine may cause kidney problems, including hemolytic uremic syndrome, thrombotic microangiopathy, and kidney failure. Check with your doctor right away if you have stomach pain, blood in the urine, fever, increased or decreased urination, pinpoint red spots on the skin, swelling of the face, fingers, feet, or lower legs, unusual bleeding or bruising, unusual tiredness or weakness, or yellow eyes or skin.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.

This medicine may cause a condition called capillary leak syndrome. It can cause fluid to leak from the blood vessels into your body's tissues. Call your doctor right away if you have swelling or puffiness and are urinating less often, trouble breathing, feeling of fullness, dizziness, or feeling faint.

Tell your doctor right away if you have seizures, headache, confusion, vision problems, unusual drowsiness, tiredness, or weakness. These could be symptoms of a serious nervous system problem called posterior reversible encephalopathy syndrome (PRES).
