  • Severe (total bilirubin >3x ULN): Not studied

Dosing Considerations

Do not substitute PO for IV/SC azacitidine

Indications and dosing regimen for PO differ from that of IV/SC azacitidine

Monitoring parameters

  • Verify pregnancy status of females of reproductive potential before initiating treatment
  • PO
    • Monitor CBC every other week for first 2 cycles and before start of each cycle thereafter
    • Increase monitoring to every other week for 2 cycles after any dose reduction for myelosuppression
  • IV or SC
    • Obtain CBC, liver chemistries and serum creatinine before first dose

Safety and efficacy not established

Azacitidine and its metabolites undergo substantial renal excretion; renal impairment may increase risk of toxicity

Select dose carefully and monitor renal function in geriatric patients; owing to increased risk of decreased renal function

No data available on use in pregnant females to evaluate for drug-associated risks

Verify pregnancy status of females of reproductive potential before initiating treatment

Animal data

  • Teratogenic and caused embryofetal lethality in animals at doses less than the recommended human dose of azacitidine
  • Advise pregnant females of the potential risk to fetus

Contraception

  • IV or SC
    • Females of reproductive potential: Avoid pregnancy during treatment
    • Males with female sexual partners of reproductive potential: Avoid pregnancy and use effective contraception during treatment
  • PO
    • Females of reproductive potential: Use effective contraception during treatment and for at least 6 months after last dose
    • Males with female sexual partners of reproductive potential: Use effective contraception during treatment and for at least 3 months after last dose

Infertility

  • PO
    • Based on animal data, male and female fertility may be impaired

Lactation

There is no information regarding presence of azacitidine in human milk, effects of therapy on breastfed infant, or effects of therapy on milk production

IV or SC: Advise patients not to breastfeed during therapy

PO: Advise patients not to breastfeed during therapy and for 1 week after last dose

Pregnancy Categories

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

azacitidine injection

AZACITIDINE - INJECTION

(ay-za-SYE-ti-deen)

COMMON BRAND NAME(S): Vidaza

USES: This medication is used to treat a group of blood/bone marrow disorders (myelodysplastic syndromes-MDS) in which the bone marrow does not produce enough healthy blood cells. People with MDS usually have problems such as infections, anemia, and easy bleeding/bruising. Azacitidine is believed to work by helping your bone marrow grow normal blood cells so you will need fewer blood transfusions. Azacitidine also kills abnormal blood cells that have grown too fast and do not work properly.

HOW TO USE: This medication is given by injection under the skin or into a vein by a health care professional.If you are receiving the injection under the skin, your health care professional will change the injection site each time to lessen injury under the skin.This medication is injected as directed by your doctor, usually once a day for 7 days in a row. A 7-day course of this medication is called a cycle. This cycle is repeated every 4 weeks depending on your response and blood tests.The dosage is based on your medical condition, body size, lab tests, and response to treatment. Keep all medical/lab appointments.

SIDE EFFECTS: Redness/pain/bruising at the injection site, tiredness, diarrhea, dizziness, trouble sleeping, constipation, nausea, vomiting, mouth sores, dry skin, headache, and loss of appetite may occur. Nausea and vomiting can be severe. In some cases, your doctor may prescribe medication to prevent or relieve nausea and vomiting. Eating several small meals, not eating before treatment, or limiting activity may help lessen some of these effects. If these effects last or worsen, tell your doctor or pharmacist promptly.People using this medication may have serious side effects. However, you have been prescribed this drug because your doctor has judged that the benefit to you is greater than the risk of side effects. Careful monitoring by your doctor may decrease your risk.Tell your doctor right away if you have any serious side effects, including: easy bleeding/bruising, chest pain, muscle/joint pain, muscle cramps, irregular heartbeat, mental/mood changes (such as anxiety), dark urine, yellowing eyes/skin.This medication may lower your ability to fight infections. This may make you more likely to get a serious (rarely fatal) infection or make any infection you have worse. Tell your doctor right away if you have any signs of infection (such as sore throat that doesn't go away, fever, chills, cough).Azacitidine sometimes causes side effects due to the rapid destruction of cancer cells (tumor lysis syndrome). To lower your risk, your doctor may add a medication and tell you to drink plenty of fluids. Tell your doctor right away if you have symptoms such as: low back/side pain (flank pain), signs of kidney problems (such as painful urination, pink/bloody urine, change in the amount of urine), muscle spasms/weakness.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.

PRECAUTIONS: Before using azacitidine, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies.
