About Nilotinib (Danziten®)

A kinase is an enzyme that helps a cell grow. There are different types of kinases. Each type affects a different phase of cell growth. Kinase inhibitors slow down the growth of cancer cells. 

How to Take Nilotinib

Nilotinib comes as a tablet to take by mouth. Swallow the tablets whole; do not crush, chew or break. If you miss a dose, take the next dose at its regular time. Do not take two doses at the same time.

It is important to 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.

There are other formulations of nilotinib. Do not switch formulations of nilotinib without talking to your provider. The dosing, drug interactions, and side effects may be different.

The blood levels of this medication can be affected by certain foods and medications, so they should be avoided. These include: grapefruit, grapefruit juice, verapamil, ketoconazole, rifampin, phenytoin, St. John’s wort, and modafinil. Be sure to tell your healthcare provider about all medications and supplements you take.

You should not take nilotinib at the same time as "heartburn" medications (including proton pump inhibitors such as Prilosec, Nexium, and Protonix, and H2 blockers like Tagamet and Zantac) as these affect how nilotinib is absorbed. If needed, take these medications 10 hours before or 2 hours after nilotinib.

If you need to take an antacid that contains aluminum hydroxide, magnesium hydroxide, or simethicone, take them 2 hours before or 2 hours after nilotinib.

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. 

Insurance Information

This medication may be covered by your prescription plan. If you qualify, you may be able to get financial help through patient assistance programs (PAP). Co-pay cards may also be available to lower your out-of-pocket cost if you have commercial (not Medicare/Medicaid/Tricare) insurance. Your pharmacist, social worker, or navigator can help find resources for financial support.

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.

QT Prolongation

QT prolongation is when your heart is not working how it should, and it can cause slow or abnormal heartbeats or an abnormal heart rhythm. Tell your provider right away if you feel abnormal heartbeats or if you feel dizzy or faint.

Your provider will do an ECG to check for this before starting this medication, 7 days after starting, with any dose changes, and every so often while on the drug.

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 with Dehydration

Diarrhea can be a serious side effect that can lead to dehydration (when you do not have enough fluid in your body). Tell your healthcare provider if you have 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 because 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.

Low White Blood Cell Count (Leukopenia or Neutropenia)

White blood cells (WBC) help your body fight infection. While you are having treatment for cancer, your WBC count can drop, putting you at a higher risk of an infection. Tell your provider right away if you have a fever (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 live with someone with 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. 

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.

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. 

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.

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.

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 2 weeks 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 2 weeks 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.

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.

Fluid Retention

Fluid retention happens when your body holds on to too much fluid or is unable to excrete (put out) fluid. You may have swelling throughout your body, bloating of your abdomen (belly) called ascites, and a hard time breathing as fluid builds up in the lining of your lungs (pleural effusion) or around your heart.

Call your provider right away if you have new or worsening swelling, unexpected weight gain, shortness of breath, or a dry cough. 

Pancreas Problems

This medication can affect your pancreas. Call your provider if you have any symptoms of pancreatitis (inflammation of the pancreas), such as:

  • Bloating,
  • Indigestion.
  • Nausea and/or vomiting.
  • Fatty stools (that are bulky, pale, oily, and sometimes float).
  • Not feeling hungry (loss of appetite).
  • Sweating.
  • Abdominal (belly) pain or swelling.
  • Weight loss.

Your provider may monitor certain blood levels with labs during and after treatment.

Blood Clots, Heart Attack, and Stroke

This medication increases your risk for blood clots, stroke, and heart attack. Symptoms may be:

  • Swelling, redness, or pain in an arm or leg.
  • Chest pain or pressure.
  • Pain in your back, neck, or jaw.
  • Shortness of breath.
  • Numbness or tingling.

Tell your provider right away if you have any of these symptoms.

Tumor Lysis Syndrome

Tumor Lysis Syndrome (TLS) is a side effect that happens when tumor cells die too quickly, and their waste overwhelms the body. You may be given a medication (allopurinol) and IV fluids to help prevent this. TLS can affect your kidney function. Your provider will monitor your kidney function with blood work. Symptoms may be:

  • Nausea.
  • Vomiting.
  • Diarrhea.
  • Lethargy (feeling tired, drowsy, sluggish).
  • Little or no urine output.

Tell your provider right away if you have any of these symptoms.

Electrolyte Abnormalities

This medication can affect your electrolytes (potassium, magnesium, sodium, calcium, etc.). Your electrolyte levels will be checked with blood tests. If your levels get too low, you may be given electrolytes by IV (intravenously through your vein) or by mouth. Talk to your provider before taking any supplements.
