• Decitabine works by slowing down the growth of cancer cells.
• It is a form of chemotherapy that alters the way cells in the body produce new DNA, especially in cancer cells.
• Cancer cells multiply rapidly, and by interfering with their DNA, Decitabine prevents them from growing and spreading.

In MDS and AML, when the body begins to produce poor quality blood cells, Decitabine helps the body to produce better quality blood cells again. Therefore, less symptoms are developed like fatigue, bleeding, and infections. Though Decitabine primarily acts on cancerous cells, some rapidly dividing healthy cells also get affected that leads to some side effects.

Although Decitabine is quite helpful, it also comes with some side effects. Some patients may not feel well when on this medicine. The common side effects include the following:

• Low Blood Counts: Decitabine lowers the count of red blood cells, white blood cells, or platelets. This leads to easy bruising, infection, or sometimes hemorrhaging.
• Fatigue: The people who take the medication are usually fatigued or weak.
• Nausea and Vomiting: A patient may feel nauseated or vomit, especially after the infusion is completed.
• Increased Risk of Infection: Since your body’s immune system can be weakened by Decitabine, you tend to catch infections more easily than usual.
• Hair loss: Some patients experience hair loss, but it is usually temporary.
• Stomach problems: This may include diarrhea or constipation.

• Pregnancy and breastfeeding: Decitabine can harm a baby if you are pregnant. It is also not known if it can pass into the milk of nursing mothers; therefore, do not breastfeed while on this medication.
• Other medical conditions: If you have kidney or liver disease, inform your doctor. He will prescribe the right dosage for your medical condition.

• Other drugs will interact with Decitabine. Among those are increased risk of side effects and ineffectiveness.
  • Other chemo drugs: Using Decitabine with other cancer drugs enhances the side effects—or at least increases risk—to blood cells.
  • Antiviral drugs: These can reduce the efficacy of Decitabine and make a patient more vulnerable to infections.
  • Blood thinners: An example of this type is warfarin. It is the medication that thins the blood. Together with Decitabine, it may further influence bleeding risk.
• Always inform your doctor about the medications that you are undergoing, even over-the-counter drugs and supplements, to avoid critical interactions.

• Decitabine The right dose to take will be provided by your doctor.
• Therapy for Decitabine will differ from the different conditions and medical conditions the patient has.
