Gemzar (gemcitabine) is a cancer medication that interferes with the growth and spread of cancer cells in the body.
Gemzar is used to treat cancers of the pancreas, lung, ovary, and breast.
Gemzar may also be used for purposes not listed in this medication guide.
Important information
Gemzar can lower blood cells that help your body fight infections and help your blood to clot. You may get an infection or bleed more easily. Call your doctor if you have unusual bruising or bleeding, or signs of infection (fever, chills, body aches).
Gemzar can affect your liver, kidneys, or lungs. Tell your doctor if you have stomach pain, dark urine, yellow skin or eyes, little or no urinating, swelling, rapid weight gain, severe shortness of breath, wheezing, or cough with foamy mucus.
If you receive Gemzar during or after radiation treatment, tell your doctor right away if you have severe skin redness, swelling, oozing, or peeling.
Before receiving Gemzar
You should not use Gemzar if you are allergic to gemcitabine.
To make sure Gemzar is safe for you, tell your doctor if you have:
-
kidney disease;
-
liver disease (especially cirrhosis);
-
a history of alcoholism; or
-
if you are receiving radiation treatment.
Do not use Gemzar if you are pregnant. It could harm the unborn baby. Use effective birth control, and tell your doctor if you become pregnant during treatment.
It is not known whether gemcitabine passes into breast milk or if it could harm a nursing baby. You should not breast-feed while you are using Gemzar.
How is Gemzar used?
Gemzar is injected into a vein through an IV. A healthcare provider will give you this injection.
Gemzar can lower blood cells that help your body fight infections and help your blood to clot. Your blood will need to be tested often. Your cancer treatments may be delayed based on the results of these tests.
If any Gemzar injection accidentally gets on your skin, wash the area thoroughly with soap and warm water.

Avoid activities that may increase your risk of bleeding or injury. Use extra care to prevent bleeding while shaving or brushing your teeth.
Gemcitabine can pass into body fluids (including urine, feces, vomit). For at least 48 hours after you receive a dose, avoid allowing your body fluids to come into contact with your hands or other surfaces.
