Decitabine and Cedazuridine (Inqovi®)
Pronounce: dee-SYE-ta-been and sed-as-URE-i-deen
Classification: DNA methylation inhibitor/Cytidine deaminase inhibitor
About Decitabine and Cedazuridine (Inqovi®)
Decitabine kills cancer cells in the bone marrow by inhibiting a process called DNA methylation, which is needed for cell reproduction. Because the abnormal cells cannot divide and grow, they die.
Cedazuridine is a cytidine deaminase inhibitor that can prevent the breakdown of cytidine enzymes. When given in combination with decitabine, it stabilizes the enzymes in the GI system, allowing for decitabine to be given orally, rather than intravenously (by vein).
How to Take Decitabine and Cedazuridine
Decitabine and Cedazuridine are taken as one tablet on an empty stomach, at least 2 hours before or after eating a meal or snack. Take the tablet whole at the same time every day. Do not break, crush, or chew it. If you miss a dose, take your dose as soon as possible if it is within 12 hours of your usual time. If you miss a dose by more than 12 hours, don’t take an additional dose to make up for the missed dose. Go back to your normal schedule the following day and contact your providers to make them aware. If you vomit after taking this medication, do not take an extra dose. Take your next dose as scheduled.
Make sure you are taking the correct amount of medication every time. Before every dose, check that what you are taking matches what you have been prescribed. In some cases, this medication might be taken with Venetoclax.
This medication can interact with other medications. Be sure to tell your provider about all medications and supplements you take.
Storage and Handling
Store your medication in the original container with the label. If you want to use a pillbox, talk to your pharmacist. Keep it in a dry place at room temperature unless your provider or pharmacist tells you otherwise. Keep containers out of reach of children and pets.
If a caregiver prepares your dose for you, they should consider wearing gloves or pour the pills directly from their container into the cap, a small cup, or directly into your hand. They should avoid touching the pills. They should always wash their hands before and after giving you the medication. Pregnant or nursing people should not prepare the dose for you. Ask your provider where to return any unused medication for disposal. Do not flush down the toilet or throw in the trash.
Where Do I Get This Medication?

Possible Side Effects
These are some of the most common or most serious side effects of this medication. Talk with your provider about the side effects you are having and how they can be managed.
Infection and Low White Blood Cell Count (Leukopenia or Neutropenia)
This medication can cause serious infections, with or without a decrease in white blood cell counts.
White blood cells (WBC) help your body fight infection. While you are having cancer treatment, your WBC count can drop, putting you at a higher risk of an infection. Tell your provider right away if you have a fever (a temperature greater than 100.4°F or 38°C), sore throat or cold, shortness of breath, cough, burning with urination, or a sore that doesn't heal.
Tips for preventing infection:
- Hand washing, both yours and your visitors, is the best way to prevent the spread of infection.
- Avoid large crowds and people who are sick (those who have a cold, fever, or cough, or if someone you live with has these symptoms).
- When working outside, wear clothes that protect you, like long pants and gloves.
- Do not handle pet waste.
- Keep all cuts and scratches clean.
- Shower or bathe daily.
- Brush your teeth at least twice a day.
- Do not cut cuticles or ingrown nails. You may wear nail polish, but not fake nails.
- Ask your providers before scheduling dental appointments or procedures.
Ask your providers before you or someone you live with has any vaccines.
Low Red Blood Cell Count (Anemia)
Anemia is when your red blood cell count is lower than normal. Red blood cells carry oxygen to the tissues in your body. When your red cell count is low, you may feel tired or weak. Tell your providers if you have shortness of breath, trouble breathing, or pain in your chest. If your count gets too low, you may receive a blood transfusion.
Low Platelet Count (Thrombocytopenia)
Platelets are blood cells that help your blood clot. Thrombocytopenia is when your platelet count is lower than normal, and you are at a higher risk of bleeding. Tell your providers if you have any bruising or bleeding, including nose bleeds, bleeding gums, or blood in your urine or stool. If your count gets too low, you may receive platelets from a donor.
- Do not use a razor (an electric razor is fine).
- Do not do activities that can cause injury or bleeding.
- Talk to your provider before taking any non-steroidal, anti-inflammatory medications (NSAIDs) like Motrin/Advil (ibuprofen), Aleve (naproxen), Celebrex (celecoxib), and others. These can raise the risk of bleeding.
- Use a soft-bristle toothbrush to brush your teeth. Ask your provider about flossing or using toothpicks.
Fatigue
Fatigue can cause exhaustion, feeling worn out and that your body is "heavy" and hard to move, or being unable to focus. It is common when you have cancer, and it is not the same as feeling tired. You may need to adjust your schedule to manage fatigue. Plan times to rest during the day and save your energy for more important activities. Exercise can help lessen fatigue. Talk to your providers about ways to deal with this side effect.
Constipation
Constipation is when you have less bowel movements than usual or are having trouble passing stool. To relieve constipation, you can include fiber in your diet (fruits like prunes, apples, peaches, and pear nectars/juices), drink 8 to 10 glasses of non-alcoholic fluids a day, and stay active. Taking a stool softener once or twice a day can prevent constipation. If you do not have a bowel movement for 2 to 3 days, call your provider.
Muscle or Joint Pain/Aches and Headache
You may have joint or muscle pain/aches and headaches while taking this medication. Your provider can recommend medications and other ways to help relieve your pain.
Mouth Ulcers (Mucositis)
This medication can cause sores or soreness in your mouth and/or throat, called mucositis. Tell your providers if your mouth, tongue, inside of your cheek, or throat becomes white, has ulcers, or is painful. Medications can be used to manage pain. Regular mouth care can help prevent or manage mouth sores. Some things you can do are:
- Brush with a soft-bristle toothbrush or cotton swab twice a day.
- Avoid mouthwashes that contain alcohol. A baking soda and/or salt with warm water mouth rinse (2 level teaspoons of baking soda or 1 level teaspoon of salt in an eight-ounce glass of warm water) can be used a few times each day.
- If your mouth gets dry, eat moist foods, drink plenty of fluids (6 to 8 glasses), and suck on sugarless hard candy.
- Avoid smoking and chewing tobacco, and drinking alcoholic beverages and citrus juices.
Shortness of Breath/Cough/Pneumonia
This medication can cause shortness of breath, coughing, and pneumonia. If you are having trouble breathing, call 911 or go to the Emergency room right away. If you have a new or worsening cough, contact your provider.
Nausea and/or Vomiting
Talk to your providers if you have nausea and/or vomiting. They can prescribe medications to help you. Making changes to your diet can also help. Avoid things that make your symptoms worse, like heavy or greasy/fatty foods and spicy or acidic foods, like tomatoes, lemons, and oranges. Try saltines or ginger ale to help your symptoms.
Call your providers if you cannot keep fluids down for more than 12 hours or if you feel lightheaded or dizzy.
Diarrhea
Diarrhea is when you pass three or more stools in a day. Your providers can suggest medications to relieve diarrhea. Do not take any medications to manage your diarrhea without talking to your provider first, as your stool may need to be tested. To manage it, try eating foods that are low in fiber and bland, like white rice and boiled or baked chicken. Try not to eat raw fruits, vegetables, whole grain breads, cereals, and seeds. Soluble fiber is a type of fiber found in some foods that helps absorb (soak up) fluid. Foods high in soluble fiber are applesauce, bananas (ripe), canned fruit, oranges, boiled potatoes, white rice, foods made with white flour, oatmeal, cream of rice, cream of wheat, and farina. Stay hydrated by drinking 8 to 10 glasses of non-alcoholic, non-caffeinated fluid each day.
Rash
Some people may get a rash, scaly skin, or red, itchy bumps from this medication. Tell your provider if you notice any of these changes in your skin, since it could be a reaction. Your provider may suggest:
- Using an alcohol-free moisturizer on your skin and lips, and do not use moisturizers with perfumes or scents.
- Keep the area clean to avoid infection, especially if it cracks or bleeds.
- Using a topical medication (applied to the skin) if the itching bothers you.
Be sure to talk with your provider about how to care for your skin.
Peripheral Edema
Peripheral edema is swelling in your hands, arms, legs, ankles, and feet. It is caused by retention (buildup) of fluid. To help get rid of the fluid, you can elevate (lift up) the affected body part and rest it on a pillow. You may need medications to help your body get rid of the extra fluid, and you may be told to follow a low salt diet. Tell your providers if you have any new or worsening swelling.
Decrease in Appetite or Taste Changes
Nutrition is an important part of your care. Cancer treatment can affect your appetite and make it hard to eat. Ask your provider about nutrition counseling services. Some tips you can follow are:
- Try to eat five or six small meals or snacks during the day, instead of 3 larger meals.
- Nutritional supplements may help if you are not eating enough.
- You may have a metallic taste or find that food has no taste. You may dislike foods or beverages that you liked before cancer treatment. These symptoms can last for months or longer after treatment ends.
- Avoid any food that you think smells or tastes bad. If red meat is a problem, eat chicken, turkey, eggs, dairy products, and fish without a strong smell. Sometimes cold food has less of an odor.
- Add extra flavor to meat or fish by marinating it in sweet juices, sweet and sour sauce, or dressing.
- Use seasonings like basil, oregano, or rosemary to add flavor.
Liver Toxicity
This medication can cause liver toxicity, or liver problems, which your provider may monitor for with blood tests called liver function tests. Symptoms may be:
- Yellowing of your skin or eyes.
- Dark or brown urine.
- Pain in your abdomen (belly).
Tell your provider if you have any of these symptoms.
Kidney Problems
This medication can cause kidney problems, like an increased creatinine level. Your provider may monitor for kidney problems with blood tests. Symptoms may be:
- Less urine output than normal.
- Blood in the urine.
- Swelling in the ankles.
- Loss of appetite.
Tell your provider if you have any of these symptoms.
Reproductive Concerns
There is a higher risk of health problems for your baby if you are pregnant, become pregnant, or get someone pregnant while on this medication. To lower the risk of birth defects, you should use birth control (contraception) to avoid pregnancy. Talk with your provider about what kind of birth control is safest for you and your partner.
If you can become pregnant, you will need to use effective birth control during treatment and for 6 months after the last dose of this medication, even if your menstrual cycle has stopped or changed. If you can get someone pregnant, you will need to use effective birth control during treatment and for 3 months after the last dose of this medication, even if you believe you are not producing sperm.
You should not breastfeed during treatment and for 2 weeks after the last dose of this medication.
