Use: Labeled Indications
Myelodysplastic syndromes: Treatment of myelodysplastic syndromes (MDS), including previously treated and untreated, de novo and secondary MDS of all French-American-British (FAB) subtypes (refractory anemia, refractory anemia with ringed sideroblasts, refractory anemia with excess blasts, refractory anemia with excess blasts in transformation, and chronic myelomonocytic leukemia) and intermediate-1, intermediate-2, and high-risk International Prognostic Scoring System (IPSS) groups
Treatment of acute myelogenous leukemia (AML), sickle cell anemia
There are no contraindications listed in the manufacturer’s labeling.
Myelodysplastic syndromes (MDS): IV:
15 mg/m2 over 3 hours every 8 hours (45 mg/m2/day) for 3 days (135 mg/m2/cycle) every 6 weeks; treatment is recommended for at least 4 cycles and may continue until the patient no longer benefits.
Adjustment for prolonged hematologic toxicity (ANC <1,000/mm3 and platelets <50,000/mm3):
>6 weeks but <8 weeks: Delay dose for up to 2 weeks and temporarily reduce dose to 11 mg/m2 every 8 hours (33 mg/m2/day) for 3 days (99 mg/m2/cycle)
>8 weeks but <10 weeks: Assess for disease progression; if no disease progression, delay dose for up to 2 weeks and reduce dose to 11 mg/m2 every 8 hours (33 mg/m2/day) for 3 days (99 mg/m2/cycle); maintain or increase dose with subsequent cycles if clinically indicated
20 mg/m2 over 1 hour daily for 5 days every 28 days (delay subsequent treatment cycles until hematologic recovery [ANC ≥1,000/mm3 and platelets ≥50,000/mm3]); treatment is recommended for at least 4 cycles and may continue until the patient no longer benefits.
Acute myeloid leukemia (AML) (off-label use): Adults ≥60 years: IV: 20 mg/m2 over 1 hour daily for 5 days every 28 days until relapse, disease progression, or unacceptable toxicity (Cashen 2010; Kantarjian 2012)
Refer to adult dosing.

Vials should be reconstituted with 10 mL SWFI to a concentration of 5 mg/mL. Immediately further dilute with NS or D5W to a final concentration of 0.1 to 1 mg/mL. Use appropriate precautions for handling and disposal. Solutions not administered within 15 minutes of preparation should be prepared with cold (2°C to 8°C [36°F to 46°F]) infusion solutions.
Infuse over 1 to 3 hours. For the treatment of myelodysplastic syndromes, administer by IV infusion over 3 hours (15 mg/m2 dose) or over 1 hour (20 mg/m2 dose). For the treatment of acute myeloid leukemia (off-label use), administer by IV infusion over 1 hour (Cashen 2010; Kantarjian 2012). Premedication with antiemetics is recommended according to the manufacturer.
See Trissel’s IV Compatibility Database
Store intact vials at 25°C (77°F); excursions permitted to 15°C to 30°C (59°F to 86°F). Solutions diluted for infusion in NS or D5W may be stored for up to 4 hours prior to infusion refrigerated at 2°C to 8°C (36°F to 46°F) if prepared with cold infusion fluids. Infusion should begin within 15 minutes of preparation if room temperature infusion solutions are utilized.

Concerns related to adverse effects:
• Bone marrow suppression: Neutropenia and thrombocytopenia commonly occur; anemia and neutropenic fever have also been reported. Myelosuppression and worsening neutropenia are more common in first two treatment cycles and may not correlate with progression of underlying MDS. Hematologic toxicity may require dosage adjustment (after the first cycle), growth factor support, and/or antimicrobial agents. Monitor for infection.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
CBC with differential and platelets (with each cycle and more frequently if needed); liver enzymes (prior to treatment initiation and periodically); serum creatinine (prior to treatment initiation and periodically)
Pregnancy Risk Factor
Adverse events were observed in animal reproduction studies. Based on the mechanism of action, decitabine may cause fetal harm if administered during pregnancy. Women of childbearing potential should be advised to use effective contraception to avoid pregnancy during treatment and for 1 month after treatment. In addition, males should be advised to avoid fathering a child while on decitabine therapy and for 2 months after treatment.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience dizziness, abdominal pain, nausea, vomiting, mouth sores, pinpoint red spots on skin, constipation, diarrhea, insomnia, lack of appetite, headache, itching, muscle pain, joint pain, anxiety, hair loss, or back pain. Have patient report immediately to prescriber signs of infection, signs of bleeding (vomiting blood or vomit that looks like coffee grounds; coughing up blood; blood in the urine; black, red, or tarry stools; bleeding from the gums; abnormal vaginal bleeding; bruises without a reason or that get bigger; or any severe bleeding or persistent bleeding), signs of high blood sugar (confusion, fatigue, more thirst, hunger, polyuria, flushing, fast breathing, or breath that smells like fruit), signs of fluid and electrolyte problems (mood changes, confusion, muscle pain or weakness, abnormal heartbeat, severe dizziness or passing out, tachycardia, more thirst, seizures, loss of strength and energy, lack of appetite, urinary retention or change in amount of urine produced, dry mouth, dry eyes, or nausea or vomiting), severe loss of strength and energy, pale skin, jaundice, swollen glands, shortness of breath, edema, blurred vision, difficulty swallowing, angina, tachycardia, or numbness and tingling (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
