What is Dacogen?
Dacogen (decitabine) is a cancer medication that interferes with the growth and spread of cancer cells in the body.
Dacogen is used to treat myelodysplastic syndromes (certain types of blood or bone marrow cancer).
Dacogen may also be used for purposes not listed in this medication guide.
Dacogen can lower blood cells that help your body fight infections and help your blood to clot. You may get an infection or bleed more easily. Call your doctor if you have unusual bruising or bleeding, or signs of infection (fever, chills, body aches).
Before receiving Dacogen, tell your doctor if you have liver or kidney disease.
Do not use Dacogen if you are pregnant. It could harm the unborn baby. Use effective birth control, and tell your doctor if you become pregnant during treatment. If a man fathers a child while using decitabine, the baby may have birth defects. Use a condom to prevent pregnancy during your treatment. Continue using condoms for at least 2 months after you stop receiving this medicine. You should not breast-feed while you are receiving this medicine.

How is Dacogen given?
Dacogen is injected into a vein through an IV. A healthcare provider will give you this injection.
In most cases, a Dacogen injection is given every 8 hours for 3 days. This 3-day treatment is usually repeated every 6 weeks. You will most likely receive at least 4 of these treatments.
You may be given other medications to prevent nausea or vomiting while you are receiving Dacogen.
Dacogen can lower blood cells that help your body fight infections and help your blood to clot. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. Your blood may need to be tested often. Your kidney or liver function may also need to be checked.
What happens if I miss a dose?
Call your doctor for instructions if you miss an appointment for your Dacogen injection.
What happens if I overdose?
Since Dacogen is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
What should I avoid?
Avoid being near people who are sick or have infections. Tell your doctor at once if you develop signs of infection.
Avoid activities that may increase your risk of bleeding or injury. Use extra care to prevent bleeding while shaving or brushing your teeth.
This medicine can pass into body fluids (including urine, feces, vomit, semen, vaginal fluid). For at least 48 hours after you receive a dose, avoid allowing your body fluids to come into contact with your hands or other surfaces. Patients and caregivers should wear rubber gloves while cleaning up body fluids, handling contaminated trash or laundry or changing diapers. Wash hands before and after removing gloves. Wash soiled clothing and linens separately from other laundry.
Body fluids should not be handled by a woman who is pregnant or who may become pregnant. Use condoms during sexual activity to avoid exposure to body fluids.
