What is the most important information I should know about gemcitabine (Gemzar)?

Do not receive gemcitabine if you are pregnant. It could harm the unborn baby.

Gemcitabine is injected into a vein through an IV. You will receive this injection in a clinic or hospital setting. Gemcitabine is usually given once a week for several weeks. The medicine must be given slowly, and the IV infusion can take up to 30 minutes to complete.

Gemcitabine can lower the blood cells that help your body fight infections. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. To be sure your blood cells do not get too low, your blood will need to be tested on a regular basis. Your kidney and liver function may also need to be checked. Do not miss any scheduled visits to your doctor.

Do not receive a "live" vaccine while you are being treated with gemcitabine, and avoid coming into contact with anyone who has recently received a live vaccine. There is a chance that the virus could be passed on to you.

If any of this medicine accidentally gets on your skin, wash the area thoroughly with soap and warm water.
