See prescribing information for cisplatin administration and hydration guidelines.
Dose Modifications
Dosage adjustments for hematologic toxicity may be required for Gemcitabine Injection and for cisplatin. Gemcitabine Injection dosage adjustment for hematological toxicity is based on the granulocyte and platelet counts taken on the day of therapy. Patients receiving Gemcitabine Injection should be monitored prior to each dose with a complete blood count (CBC), including differential and platelet counts. If marrow suppression is detected, therapy should be modified or suspended according to the guidelines in Table 3. For cisplatin dosage adjustment, see manufacturer’s prescribing information.
In general, for severe (Grade 3 or 4) non-hematological toxicity, except alopecia and nausea/vomiting, therapy with Gemcitabine Injection plus cisplatin should be held or decreased by 50% depending on the judgment of the treating physician. During combination therapy with cisplatin, serum creatinine, serum potassium, serum calcium, and serum magnesium should be carefully monitored (Grade 3/4 serum creatinine toxicity for Gemcitabine Injection plus cisplatin was 5% versus 2% for cisplatin alone).
2.4 Pancreatic CancerGemcitabine Injection should be administered by intravenous infusion at a dose of 1000 mg/m2 over 30 minutes once weekly for up to 7 weeks (or until toxicity necessitates reducing or holding a dose), followed by a week of rest from treatment. Subsequent cycles should consist of infusions once weekly for 3 consecutive weeks out of every 4 weeks.
Dose Modifications
Dosage adjustment is based upon the degree of hematologic toxicity experienced by the patient [see Warnings and Precautions (5.2)]. Clearance in women and the elderly is reduced and women were somewhat less able to progress to subsequent cycles [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.3)].
Patients receiving Gemcitabine Injection should be monitored prior to each dose with a complete blood count (CBC), including differential and platelet count. If marrow suppression is detected, therapy should be modified or suspended according to the guidelines in Table 3.

Laboratory evaluation of renal and hepatic function, including transaminases and serum creatinine, should be performed prior to initiation of therapy and periodically thereafter. Gemcitabine Injection should be administered with caution in patients with evidence of significant renal or hepatic impairment as there is insufficient information from clinical studies to allow clear dose recommendation for these patient populations.
Patients treated with Gemcitabine Injection who complete an entire cycle of therapy may have the dose for subsequent cycles increased by 25%, provided that the absolute granulocyte count (AGC) and platelet nadirs exceed 1500 x 106/L and 100,000 x 106/L, respectively, and if non-hematologic toxicity has not been greater than WHO Grade 1. If patients tolerate the subsequent course of Gemcitabine Injection at the increased dose, the dose for the next cycle can be further increased by 20%, provided again that the AGC and platelet nadirs exceed 1500 x 106/L and 100,000 x 106/L, respectively, and that non-hematologic toxicity has not been greater than WHO Grade 1.
2.5 Dose Modifications for Non-Hematologic Adverse ReactionsPermanently discontinue Gemcitabine for any of the following
Unexplained dyspnea or other evidence of severe pulmonary toxicity Severe hepatic toxicity Hemolytic-Uremic Syndrome Capillary Leak Syndrome Posterior reversible encephalopathy syndromeWithhold Gemcitabine or reduce dose by 50% for other severe (Grade 3 or 4) non-hematological toxicity until resolved. No dose modifications are recommended for alopecia, nausea, or vomiting.
2.6 Preparation and Administration PrecautionsCaution should be exercised in handling and preparing Gemcitabine Injection and diluted solution. The use of gloves is recommended. If Gemcitabine Injection and diluted solution contacts the skin or mucosa, immediately wash the skin thoroughly with soap and water or rinse the mucosa with copious amounts of water. Although acute dermal irritation has not been observed in animal studies, 2 of 3 rabbits exhibited drug-related systemic toxicities (death, hypoactivity, nasal discharge, shallow breathing) due to dermal absorption.
Procedures for proper handling and disposal of anti-cancer drugs should be considered. Several guidelines on this subject have been published [see References (15)].
2.7 Preparation for Intravenous Infusion AdministrationEach vial contains a gemcitabine concentration of 38 mg/mL. Hence, withdrawing 5.26 mL, 26.3 mL, or 52.6 mL of the vial contents will provide 200 mg, 1 g, or 2 g of gemcitabine, respectively. The appropriate amount of drug should be further diluted with 0.9% Sodium Chloride Injection to concentrations as low as 0.1 mg/mL.
After dilution with 0.9% Sodium Chloride Injection the solution should be inspected visually for particulate matter and discoloration, prior to administration, whenever solution or container permits. If particulate matter or discoloration is found, do not administer.
When prepared as directed, diluted gemcitabine solutions are stable for 24 hours at controlled room temperature 20° to 25°C (68° to 77°F) [see USP Controlled Room Temperature]. Discard unused portion.
The compatibility of Gemcitabine Injection with other drugs has not been studied. No incompatibilities have been observed with infusion bottles or polyvinyl chloride bags and administration sets.

Gemcitabine Injection should be administered with caution in patients with evidence of significant renal or hepatic impairment as there is insufficient information from clinical studies to allow clear dose recommendation for these patient populations.
Patients treated with Gemcitabine Injection who complete an entire cycle of therapy may have the dose for subsequent cycles increased by 25%, provided that the absolute granulocyte count (AGC) and platelet nadirs exceed 1500 x 106/L and 100,000 x 106/L, respectively, and if non-hematologic toxicity has not been greater than WHO Grade 1. If patients tolerate the subsequent course of Gemcitabine Injection at the increased dose, the dose for the next cycle can be further increased by 20%, provided again that the AGC and platelet nadirs exceed 1500 x 106/L and 100,000 x 106/L, respectively, and that non-hematologic toxicity has not been greater than WHO Grade 1.
2.5 Dose Modifications for Non-Hematologic Adverse ReactionsPermanently discontinue Gemcitabine for any of the following
Unexplained dyspnea or other evidence of severe pulmonary toxicity Severe hepatic toxicity Hemolytic-Uremic Syndrome Capillary Leak Syndrome Posterior reversible encephalopathy syndromeWithhold Gemcitabine or reduce dose by 50% for other severe (Grade 3 or 4) non-hematological toxicity until resolved. No dose modifications are recommended for alopecia, nausea, or vomiting.
2.6 Preparation and Administration PrecautionsCaution should be exercised in handling and preparing Gemcitabine Injection and diluted solution. The use of gloves is recommended. If Gemcitabine Injection and diluted solution contacts the skin or mucosa, immediately wash the skin thoroughly with soap and water or rinse the mucosa with copious amounts of water. Although acute dermal irritation has not been observed in animal studies, 2 of 3 rabbits exhibited drug-related systemic toxicities (death, hypoactivity, nasal discharge, shallow breathing) due to dermal absorption.
Procedures for proper handling and disposal of anti-cancer drugs should be considered. Several guidelines on this subject have been published [see References (15)].
2.7 Preparation for Intravenous Infusion AdministrationEach vial contains a gemcitabine concentration of 38 mg/mL. Hence, withdrawing 5.26 mL, 26.3 mL, or 52.6 mL of the vial contents will provide 200 mg, 1 g, or 2 g of gemcitabine, respectively. The appropriate amount of drug should be further diluted with 0.9% Sodium Chloride Injection to concentrations as low as 0.1 mg/mL.
After dilution with 0.9% Sodium Chloride Injection the solution should be inspected visually for particulate matter and discoloration, prior to administration, whenever solution or container permits. If particulate matter or discoloration is found, do not administer.
When prepared as directed, diluted gemcitabine solutions are stable for 24 hours at controlled room temperature 20° to 25°C (68° to 77°F) [see USP Controlled Room Temperature]. Discard unused portion.
The compatibility of Gemcitabine Injection with other drugs has not been studied. No incompatibilities have been observed with infusion bottles or polyvinyl chloride bags and administration sets.
