Why is this medication prescribed?

Onureg (generic name: azacitidine) is a medication that is primarily prescribed for the treatment of a specific type of blood cancer called acute myeloid leukemia (AML). AML is a cancer that affects the bone marrow and blood cells, leading to the rapid growth of abnormal white blood cells.

Onureg is specifically used as maintenance therapy for adult patients with AML who have achieved complete remission (the absence of detectable cancer cells) after intensive chemotherapy. It is prescribed to help prevent the recurrence of leukemia by suppressing the growth of remaining cancer cells and prolonging the duration of remission.

The active ingredient in Onureg, azacitidine, is a type of chemotherapy drug that works by inhibiting the DNA synthesis in cancer cells, leading to their destruction. It is taken orally as a once-daily pill, making it a convenient treatment option for patients who have completed intensive chemotherapy.

How should this medicine be used?

Onureg (azacitidine) is typically available in the form of oral tablets and should be used as directed by your healthcare provider. Here are some general guidelines for the use of Onureg:

  • Dosage: The recommended starting dose of Onureg is usually 300 mg (three tablets) taken once daily for 14 days of a 28-day treatment cycle. The tablets should be swallowed whole with a glass of water and can be taken with or without food.
  • Cycle: Each treatment cycle consists of 28 days, with 14 days on treatment followed by 14 days off treatment. This 28-day cycle is repeated unless your doctor advises otherwise.
  • Compliance: It is important to take Onureg exactly as prescribed by your healthcare provider. Do not modify the dosage or schedule without consulting your doctor.
  • Missed Dose: If you miss a dose, take it as soon as you remember on the same day. If it is already the next day, skip the missed dose and resume the regular dosing schedule. Do not take a double dose to make up for a missed one.
  • Duration: Your doctor will determine the duration of your treatment with Onureg. It is typically prescribed for long-term maintenance therapy to prevent the recurrence of acute myeloid leukemia (AML).
  • Follow-up: Regular follow-up visits with your healthcare provider are essential to monitor your progress, evaluate any side effects, and adjust your treatment plan if necessary.

It is crucial to adhere to your doctor’s instructions and communicate any concerns or side effects you may experience during the treatment with Onureg. They will be able to provide personalized guidance based on your specific condition and response to the medication.

Other uses for this medicine

Onureg (azacitidine) is primarily prescribed for the treatment of acute myeloid leukemia (AML) as maintenance therapy. However, it’s important to note that medications can sometimes be prescribed off-label, meaning they may be used for conditions or purposes other than those specifically approved by regulatory authorities. It is best to consult with a healthcare professional to determine if Onureg is being used for any other specific indications beyond AML.

What special precautions should I follow?

Regarding special precautions, here are some important points to consider when using Onureg:

  • Pregnancy and breastfeeding: Onureg may cause harm to unborn babies, so it is not recommended during pregnancy unless the potential benefits outweigh the risks. It is also advised to avoid breastfeeding while taking Onureg, as it may pass into breast milk and harm the nursing infant.
  • Blood disorders: Onureg can cause bone marrow suppression, leading to low blood cell counts. Regular monitoring of blood counts is necessary during treatment. If you experience symptoms such as easy bleeding or bruising, persistent infections, or fatigue, inform your healthcare provider.
  • Liver or kidney problems: Individuals with pre-existing liver or kidney problems may require dose adjustments or closer monitoring while taking Onureg. Inform your doctor about any history of liver or kidney conditions.
