About Pazopanib (Votrient®)

This medication is a type of targeted therapy called a tyrosine kinase inhibitor. A kinase is an enzyme that promotes cell growth. There are many types of kinases, which control different phases of cell growth. By blocking a particular enzyme from working, this medication can slow the growth of cancer cells.

This medication is a tyrosine kinase inhibitor that blocks a few targets including VEGF, PDFR, FGFR, cKIT, IL-2, LcK and c-Fms. This means it works by targeting receptors present on the cancer cells. By blocking these targets on cancer cells, tumor growth and angiogenesis (the development of a blood supply to the tumor) are blocked.

How to Take Pazopanib

This medication comes as a tablet to take by mouth. It should be taken without food, on an empty stomach, at least 1 hour before or 2 hours after a meal. Take the tablets whole; do not crush, break or chew. Take this medication at around the same time every day. If you miss a dose and it has been less than 12 hours since your regular dose time, take it as soon as you remember. If it has been more than 12 hours, skip the dose. Do not take 2 doses at once to make up for a missed dose.

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.

The blood levels of this medication can be affected by certain foods and medications, so they should be avoided. These include: grapefruit, grapefruit juice, amiodarone, atorvastatin, azithromycin, carvedilol, carbamazepine, citalopram, fluoxetine, hydroxychlorquine, itraconazole, ketoconazole, phenobarbital, phenytoin, posaconazole, quetiapine, rifampin, sotalol, St. John’s wort, verapamil, and voriconazole.

You should not take this medication at the same time as "heartburn" medications (including proton pump inhibitors such as prilosec, nexium, protonix, and H2 blockers such as tagamet, zantac), as these may affect how this medication is absorbed. If needed, take these medications 2 hours before or after this medication.

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?

Some cancer medications are only available through specialty pharmacies. Your provider or pharmacist will start this process. Your insurance plan may also affect where you can get your medication.  Call your prescription plan provider to find out which specialty pharmacies are in-network.

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.

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.

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.

High Blood Sugar

This medication can cause high blood sugar in patients with and without diabetes. Symptoms can be:

  • Feeling more thirsty.
  • More frequent urination.
  • Feeling hungrier. 
  • Blurry vision.
  • Headaches.
  • Breath smelling like fruit.

All patients will have their blood sugar checked with blood tests. If you have diabetes and your blood sugars are higher than normal, talk to your provider. Tell your provider if you have any of these symptoms.

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.

High Blood Pressure

This medication can cause high blood pressure (hypertension). You should have your blood pressure checked often during therapy, so that if you have high blood pressure, it can be treated. If your blood pressure cannot be controlled, your provider may want you to stop taking the medication. Tell your providers about any headaches, vision changes, or dizziness. 

Changes in Hair Color

This medication has been shown to change the color or texture of your hair. If your hair changes color, it is called "depigmentation." This will not cause any pain, but talk with your provider if you have any concerns.

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

Electrolyte Abnormalities

This medication can affect your electrolytes (potassium, magnesium, 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. 

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. 

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.

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.

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.

Fertility

This medication may affect your fertility. It can cause changes to your menstrual cycle or sperm. You may want to consider sperm banking or egg harvesting if you might wish to have a child in the future. Talk about your options with your provider before treatment.

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 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 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.

Important but Less Common Side Effects

Heart Problems

This medication can cause cardiac problems. Be sure your provider is aware if you have or have had any heart problems in the past.

  • This medication can cause abnormal heart rhythm called QT prolongation. Your provider will perform ECG testing and monitor electrolytes with blood tests. Call your provider right away if you feel abnormal heartbeats or if you feel dizzy or faint
  • This medication can cause new or worsening heart failure. Your provider may monitor your heart function before and during treatment. Report any swelling, rapid weight gain, or shortness of breath.

Thyroid Problems

This medication can cause hypothyroidism (underactive thyroid). Your provider will do blood tests to check the function of your thyroid and treat this side effect if it develops. Symptoms of thyroid problems can be tiredness, feeling hot or cold, change in your voice, weight gain or loss, hair loss, and muscle cramps.

Proteinuria

Proteinuria is when there is protein in your urine. This can be a sign of kidney damage. When the kidney’s filters are damaged, protein leaks into the urine. Often, there are no symptoms. Your provider will check your urine (called a urinalysis) and test your blood for your kidney function while you are on this medication.

Gastrointestinal (GI) Bleed & Tear

This medication can cause bleeding or a tear in the wall of your gastrointestinal (GI) system. Signs of these problems are:

  • Bright red blood in your stool or black stools.
  • Coughing up blood.
  • Vomiting blood or vomit that looks like coffee grounds.
  • Fever.
  • Severe pain in your abdomen (belly) or new abdominal swelling.

If you have any of these symptoms, call 911.

Lung Changes

This medication may cause a collapsed lung (pneumothorax) or interstitial lung disease. Patients can also develop an inflammation of the lungs (called pneumonitis) while taking this medication. Call your provider right away if you develop any new or worsening symptoms, including shortness of breath, trouble breathing, cough, or fever.

Thrombocytopenic Purpura/Hemolytic Uremic Syndrome (TTP/HUS)

This medication can cause a rare blood-clotting disorder called thrombotic thrombocytopenic purpura or hemolytic uremic syndrome (TTP or HUS). Symptoms may be:

  • Bruising.
  • Bleeding.
  • Tiny red or purple spots on the skin.
  • Pale skin, lips, or inner eyelids.
  • Fatigue and weakness.
  • Yellowing of the skin or eyes.

Your provider will monitor you for TTP and HUS during treatment. Tell your provider if you have any of these symptoms.

  • Headache.
  • Seizure.
  • Lethargy (feeling tired, drowsy, sluggish).
  • Confusion.
  • Blindness and other vision changes.
  • Neurological problems.

Tell your provider about any of these symptoms right away.

Wound Healing

If you have a wound, this medication can affect how it heals. It can make your wound heal very slowly or not heal completely (like a surgical wound not healing or not staying closed). If you are having a procedure or surgery:

  • Tell your provider that you have a surgical procedure planned.
  • Tell the surgeon that you are taking this medication.
  • This medication will likely be stopped before you have any surgery. 
  • Any surgical incision should be fully healed before starting or restarting this medication. 

If you have a surgical wound that has not healed or starts to have signs of infection (redness, swelling, warmth), tell your provider.

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.
