Onureg

Used for Leukemia
Used for Leukemia

Onureg (azacitidine) is a first-choice oral medication used for maintenance treatment of acute myeloid leukemia (AML). This medication is only for people who no longer have signs and symptoms of AML (complete remission) after receiving induction chemotherapy, but aren’t able to complete intensive curative therapy, like a stem cell (bone marrow) transplant. It can help people with this condition live longer. Onureg (azacitidine) is only taken for 2 weeks during each monthly chemotherapy cycle. But it can put you at risk for serious side effects, such as infections, nausea, and diarrhea.

How Onureg (azacitidine) works

Onureg (azacitidine) is a chemotherapy medication called a hypomethylating agent. It works by inserting itself in the genetic material of cancer cells. By doing this, Onureg (azacitidine) turns on certain genes that help kill cancer cells. As a result, AML cells no longer grow out of control.

Pharmacist tips for Onureg (azacitidine)

pharmacist

  • Take Onureg (azacitidine) with or without food at the same time every day. Swallow the tablet whole. Don’t cut, chew, or crush the tablet.

    • You’re more likely to experience nausea or vomiting with Onureg (azacitidine) during the first 2 cycles of treatment. Your provider will prescribe you anti-nausea medication, such as ondansetron (Zofran) or prochlorperazine, to ease these symptoms. Take these medications 30 minutes before taking each dose of Onureg (azacitidine), for at least the first 2 cycles of treatment. If you don’t experience any nausea, your provider might stop the nausea medications for future cycles.

      • If you miss a dose of Onureg (azacitidine), or vomit after taking a dose, don’t take another dose that day. Take your next dose at the normally scheduled time.

        • Ask your provider or pharmacist about the best way to handle and throw away Onureg (azacitidine) safely. Anticancer medications can be very harmful to people who handle or come into contact with them.

          faqs

          Frequently asked questions about Onureg (azacitidine)

          How long should I take Onureg (azacitidine)?
          Talk with your provider if you’re not sure how long you will be taking Onureg (azacitidine). This medication is approved as a maintenance treatment for people with AML. Typically, this means you'll continue to take Onureg (azacitidine) until it stops working for you or you have side effects that you can't tolerate. According to clinical trials, people who took Onureg (azacitidine) lived almost a year longer compared with those who didn’t.
          Does Onureg (azacitidine) cause hair loss?
          No, Onureg (azacitidine) shouldn’t cause hair loss. People who took Onureg (azacitidine) during clinical trials didn’t report hair loss as a side effect. But, other chemotherapies used to treat AML might cause hair loss. If you’re concerned about hair loss, ask your provider if the other medications you’re taking can cause this condition. If they do, your provider can recommend some treatment options to minimize hair loss.
          If I'm taking injectable azacitidine, is it possible for me to change to the oral form?
          Ask your provider if you have questions about whether it's possible for you to switch from injectable azacitidine to the oral form. The injectable and oral form of azacitidine aren't FDA-approved to treat the same type of cancer, so changing from one form to the other might not be appropriate, depending on the type of cancer you have. For example, injectable azacitidine is approved for treating AML in kids (although it's sometimes used off-label for AML in adults) and myelodysplastic syndromes (MDS). Onureg (azacitidine) is only FDA-approved for AML maintenance treatment in adults and not recommended for people with MDS.
          Is Onureg (azacitidine) safe in pregnancy?
          Onureg (azacitidine) isn’t recommended for use in pregnancy. While this medication hasn’t been well-studied in human pregnancies, animal studies show that it might cause harm to your unborn baby. Your healthcare provider might give you a pregnancy test before you begin Onureg (azacitidine). If you’re a female of childbearing age, you should use birth control while taking Onureg (azacitidine) and for at least 6 months after the last dose. Let your provider know right away if you become pregnant while taking this medication. And if you’re a male and have a partner who’s able to become pregnant, you should use birth control during treatment with Onureg (azacitidine) and for at least 3 months after the last dose.
          Is Onureg (azacitidine) safe while breastfeeding?
          It isn’t recommended to breastfeed while taking Onureg (azacitidine). We don’t know if the medication can pass into your breast milk because it hasn’t been studied in nursing mothers. But there’s a risk of serious harm to nursing infants if it does. Because of this risk, you shouldn’t breastfeed while taking Onureg (azacitidine) and for 1 week after your last dose. Talk with your provider about other ways to feed your baby during treatment.

          What are the risks and warnings for Onureg (azacitidine)?

          Onureg (azacitidine) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

          risk-warning

          Low blood cell counts

          Onureg (azacitidine) can cause your red blood cell, white blood cell, and platelet counts to drop. When these cell counts are lower than normal, you might get tired more easily or be at higher risk for bleeding and developing infections. Your provider will check your blood cell counts every other week during your first 2 chemotherapy cycles, and then monthly before the start of each cycle. Let your provider know if you develop a fever or start to feel sick, have any unusual bruising or bleeding, or feel very tired or out of breath. If this happens you might need to have your dose lowered or stop this medication altogether.

          risk-warning

          Risk of early death in people with certain blood problems (myelodysplastic syndromes)

          • Risk factors: Myelodysplastic syndrome

            If you have a blood condition called myelodysplastic syndrome (MDS), let your provider know because Onureg (azacitidine) isn't recommended for you. Clinical trials showed that there's a higher risk for early death (typically from sepsis) after Onureg (azacitidine) treatment for people with MDS than people without MDS. If you have MDS, ask your provider about other treatment options.

            risk-warning

            Possible risk of harm to an unborn baby

            Based on animal studies, Onureg (azacitidine) can harm an unborn baby if taken by mothers during pregnancy. Because of these risks, females who are able to become pregnant should use birth control during Onureg (azacitidine) treatment and for at least 6 months after the last dose. Let your provider know right away if you become pregnant while you’re still receiving Onureg (azacitidine).

            If you’re male and have a partner who’s able to become pregnant, you should use birth control during treatment with Onureg (azacitidine) and for at least 3 months after the last dose.

            risk-warning

            Possible risk for fertility problems

            Onureg (azacitidine) might cause fertility problems in males and females. This can affect your ability to have children. Let your healthcare provider know if you have concerns about fertility before starting Onureg (azacitidine).
