Description
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.
This product is available in the following dosage forms:
- Solution
- Powder for Solution

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
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:
- If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
- Check with your doctor immediately if you notice any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.
- Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Also, check with your medical doctor before having any dental work done.
- Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
- Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
- Avoid contact sports or other situations where bruising or injury could occur.
