              • Therapy can cause fetal harm when administered to a pregnant woman

              Females

              • Because of potential for genotoxicity, advise females of reproductive potential to use effective contraception during treatment and for 6 months after final dose

              Males

              • Because of potential for genotoxicity, advise males with female partners of reproductive potential to use effective contraception during treatment and for 3 months after final dose

              Lactation

              There are no data on presence of drug in human milk, or effects of gemcitabine on breastfed infant or milk production; because of potential for serious adverse reactions in nursing infants from therapy, advise a lactating woman not to breastfeed during treatment and for one week after the final dose

              Pregnancy Categories

              A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

              B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

              C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

              D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

              X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

              NA: Information not available.

              Pharmacology

              Mechanism of Action

              Pyrimidine analog; inhibits DNA synthesis by inhibiting the ribonucleotide reductase, cell cycle-specific for the S-phase of the cycle (also blocks cellular progression at G1/S-phase)

              Metabolized by nucleoside kinases to diphosphate (dFdCDP) and triphosphate (dFdCTP) nucleosides

              Gemcitabine diphosphate inhibits ribonucleotide reductase, resulting in reductions in deoxynucleotide concentrations, including dCTP

              Gemcitabine triphosphate competes with dCTP for incorporation into DNA; reduction in the intracellular concentration of dCTP by the action of the diphosphate enhances the incorporation of gemcitabine triphosphate into DNA (self-potentiation)

              After the gemcitabine nucleotide is incorporated into DNA, only one additional nucleotide is added to the growing DNA strands, which eventually results in the initiation of apoptotic cell death

              Distribution

              Vd was increased with infusion length

              Vd: 50 L/m² (following infusions lasting <70 minutes); 370 L/m² (long infusions)

              Metabolism

              Active metabolite, gemcitabine triphosphate, can be extracted from peripheral blood mononuclear cells

              Elimination

              Excretion: Urine (92-98%)

              Half-life: 1.7-19.4 hr

              Clearance

              • Male: 92.2 L/hr/m² (29 years); 75.7 L/hr/m² (45 years); 55.1 L/hr/m² (65 years); 40.7 L/hr/m² (79 years)
              • Female: 69.4L/hr/m² (29 years); 57 L/hr/m² (45 years); 41.5 L/hr/m² (65 years); 30.7 L/hr/m² (79 years)

              Lyophilized powder

              • Reconstitute 200 mg vial with 5 mL 0.9% NaCl or 1000 mg vial with 25 mL 0.9% NaCl
              • Resulting solution is 38 mg/mL
              • The appropriate dose may be further diluted with 0.9% NaCl to concentrations as low as 0.1 mg/mL

              Solution for injection (from either 38 mg/mL or 100 mg/mL vials)

              • Inspect solution and discard vial if particulate matter or discoloration is observed

              • Do not shake; mix diluted solution by gentle inversion

              Premixed Bag

              • Infusion bag selection
                • Premixed bags are ready for infusion and do not require any further preparation prior to use

              Infuse over 30 minutes

              If two premixed infusion bags are required, infuse the total volume of both bags over 30 minutes.

              Remove overwrap; check for leaks by squeezing the inner bag firmly

              If leaks are found, discard the bag

              Injection is a clear, colorless solution

              Visually inspect for any particulate matter or discoloration prior to use

              Discard if particulate matter or discoloration is found

              Follow applicable special handling and disposal procedures; exercise caution and wear gloves when handling drug; immediately wash the skin thoroughly or rinse the mucosa with copious amounts of water if drug contacts the skin or mucus membranes

Stay away from anyone who has an infection that may easily spread (such as chickenpox, COVID-19, measles, flu). Talk to your doctor if you have been exposed to an infection or for more details.Tell your health care professional that you are using gemcitabine before having any immunizations/vaccinations. Avoid contact with people who have recently received live vaccines (such as flu vaccine inhaled through the nose).To lower the chance of getting cut, bruised, or injured, use caution with sharp objects like razors and nail cutters, and avoid activities such as contact sports.Older female adults are more sensitive to the side effects of this medication, especially the risk of infection and easy bruising/bleeding.Tell your doctor if you are pregnant or plan to become pregnant. You should not become pregnant while using gemcitabine. Gemcitabine may harm an unborn baby. Your doctor should order a pregnancy test before you start this medication. Women using this medication should ask about reliable forms of birth control during treatment and for 6 months after the last dose.
