Regorafenib (Stivarga®)

Regorafenib comes in tablets, so you can take it at home.

During treatment, you usually see a:

• cancer doctor
• cancer nurse or specialist nurse
• specialist pharmacist.

This is who we mean when we mention doctor, nurse or pharmacist in this information.

You will have regular blood samples taken during your treatment to check:  

• the levels of different blood cells in your body – your blood count 
• how your liver and kidneys are working.

Your doctor, nurse or pharmacist will give you the regorafenib tablets to take home. They may also give you anti-sickness drugs and other medicines to take home. Always take these exactly as explained. This is important to make sure they work as well as possible for you.

You usually take regorafenib tablets once a day for 21 days. You then have a break for 7 days. The total 28 days is called a cycle of treatment.

You usually keep taking regorafenib for as long as it works for you and the side effects are manageable. Your nurse, pharmacist or doctor will discuss your treatment plan with you.

You take regorafenib once a day. Try to take the tablets at the same time each day. You should take them after a light, low-fat meal. This meal could include all of the following:

• a small bowl of cereal
• a glass of skimmed milk or apple juice
• a slice of toast with jam
• a cup of tea or coffee.

Swallow the tablets whole with a glass of water. Do not chew, break or crush them.

You should avoid eating grapefruit or drinking grapefruit juice while taking regorafenib. It may affect how this treatment works.

If you forget to take the tablets, you should take the missed dose as soon as possible on the same day. Do not take 2 doses on the same day to make up for a missed dose.

If you are sick just after taking the tablets, contact the hospital. Do not take another dose.

Other things to remember about your tablets:

• Keep them in the original package.
• Keep them safe and out of sight and reach of children.
• If your treatment is stopped, return any unused tablets to the pharmacist.

This treatment can increase your risk of infection. Any infection is usually mild, but it is important to get it treated as soon as possible. Contact the hospital straight away on the 24-hour contact number you have been given if:

• your temperature goes over 37.5°C (99.5°F)
• you suddenly feel unwell, even with a normal temperature
• you have symptoms of an infection
• your temperature goes below 36°C (96.8°F).

Symptoms of an infection include:

• feeling shivery and shaking
• a sore throat
• a cough
• breathlessness
• diarrhoea
• needing to pass urine (pee) a lot, or discomfort when you pass urine.

This treatment can reduce the number of platelets in your blood. Platelets are cells that help the blood to clot.

If the number of platelets is low, you may bruise or bleed easily. You may have:

• nosebleeds
• bleeding gums
• heavy periods
• blood in your urine (pee) or stools (poo)
• tiny red, brown or purple spots that may look like a rash – these spots can be harder to see if you have black or brown skin. 

If you have any unexplained bruising or bleeding, contact the hospital straight away on the 24-hour number. You may need a drip to give you extra platelets. This is called a platelet transfusion.

This treatment can reduce the number of red blood cells in your blood. Red blood cells carry oxygen around the body. If the number of red blood cells is low, this is called anaemia. You may feel:

• very low in energy
• breathless 
• dizzy and light-headed. 

If you have these symptoms, contact the hospital straight away on the 24-hour number. You may need treatment for anaemia. If you are very anaemic, you may need a drip to give you extra red blood cells. This is called a blood transfusion.

Sometimes this treatment may cause a perforation (hole) in the bowel. This is not common, but needs urgent treatment. Contact the hospital straight away if:

• you have severe pain in the tummy, and you feel sick and are vomiting
• you are bleeding from the back passage
• you have black stools (poo)
• you are vomiting blood
• your vomit looks dark and grainy, like coffee grounds.

This treatment can affect the palms of your hands and the soles of your feet. This is called palmar-plantar or hand-foot syndrome. 

If you have white skin these areas may become red. If you have black or brown skin, these areas might get darker. 

The skin on the palms of your hands and the soles of your feet may:

• be sore
• be painful, tingle, or swell
• peel, crack or blister. 

If you have any of these symptoms, contact the hospital straight away on the 24-hour number. They can give you advice. This is especially important if you have any broken skin or if walking is difficult. They can prescribe creams and painkillers to help.

You can care for your hands and feet by: 

• keeping your hands and feet cool by washing in cool water
• gently moisturising your hands and feet regularly
• wearing gloves to protect your hands and nails when working in the house or garden
• wearing loose cotton socks and avoiding tight-fitting shoes and gloves.

This treatment may affect your skin. It may cause a rash, which might be itchy. If your skin feels dry, try using an unperfumed moisturising cream every day. Your doctor, nurse or pharmacist can tell you what to expect.

Always tell them about any changes to your skin. They can give you advice and may prescribe creams or medicines to help.

Rarely, this treatment can cause a serious skin reaction that needs to be treated immediately in hospital. 

Do not take any more of this treatment and contact the hospital straight away on the 24-hour number if you have any of these symptoms:

• a skin rash that is spreading
• blistering or peeling skin
• flu-like symptoms, such as a high temperature and joint pain
• sores on your lips or in your mouth.

This treatment may cause diarrhoea. Diarrhoea means passing more stools (poo) than is normal for you, or having watery or loose stools. You may also have stomach cramps. If you have a stoma, it may be more active than usual. 

If you are passing loose stools 3 or more times a day and this is not normal for you, contact the hospital as soon as possible on the 24-hour number. Follow the advice they give you about:

• taking anti-diarrhoea medicines 
• drinking enough fluids to keep you hydrated and to replace lost salts and minerals
• any changes to your diet that might help. 

They might also ask you for a specimen of your stool to check for infection.

This treatment may cause a sore mouth and throat. You may also get mouth ulcers. This can make you more likely to get a mouth or throat infection. Use a soft toothbrush to clean your teeth or dentures in the morning, at night and after meals.

Contact the hospital straight away on the 24-hour number, if:

• a sore mouth or throat affects how much you can drink or eat 
• your mouth, tongue, throat or lips have any blisters, ulcers or white patches. 

They can give you advice, and mouthwash or medicines to help with the pain or to treat any infection. Follow their advice and make sure you:

• drink plenty of fluids
• avoid alcohol and tobacco
• avoid food or drinks that irritate your mouth and throat.

This treatment can cause constipation. Constipation means that you are not able to pass stools (poo) as often as you normally do. It can become difficult or painful. Here are some tips that may help:

• Drink at least 2 litres (3½ pints) of fluids each day.
• Eat high-fibre foods, such as fruit, vegetables and wholemeal bread.
• Do regular gentle exercise, like going for short walks.

If you have constipation, contact the hospital on the 24-hour number for advice. They can give you drugs called laxatives to help. 

If you have not been able to pass stools for over 2 days and are being sick, contact the 24-hour number straight away. 

Some foods may taste different or have no taste. Try different foods to find out what tastes best to you. You may also get a bitter or metallic taste in your mouth. Your doctor, nurse or pharmacist can give you advice. It might help to try:

• sucking sugar-free sour or boiled sweets
• eating cold foods
• eating sharp-tasting fresh fruit.

Taste changes usually get better after treatment ends. We have more information about coping with changes to taste.

This treatment can affect your appetite. Don’t worry if you do not eat much for 1 or 2 days. But if your appetite does not come back after a few days, or if you are losing weight, tell your doctor, nurse or pharmacist. They can give you advice. They may give you food or drink supplements. Or they may suggest changes to your diet or eating habits to help.

Feeling tired is a common side effect. Try to pace yourself and plan your day so you have time to rest between activities.

Being physically active can help to manage tiredness and give you more energy. It also:

• helps you sleep better
• reduces stress
• improves your bone health.

If you feel sleepy, do not drive or operate machinery.

You might notice that your hair slowly gets thinner. But you are very unlikely to lose all the hair from your head. Your hair can also become more brittle. Your nurse can give you information about coping with hair loss. Your hair will usually go back to normal after treatment ends.

This treatment can affect how the liver works. You will have regular blood tests to check this. Sometimes liver changes can be serious. Contact the hospital straight away on the 24-hour number if you have any of these symptoms:

• yellow skin or eyes
• feeling very sleepy
• dark urine (pee)
• unexplained bleeding or bruising
• pain in the right side of your tummy (abdomen).

Wounds may take longer to heal while you are taking this treatment. If you have any wounds which are not healing or look infected, contact the hospital on the 24-hour number.

Your doctor, nurse or pharmacist can explain what to do if you need surgery. It is important to stop taking regorafenib before the operation. Ask your cancer team when you should stop and start taking it. You can usually start taking it again when the wound is fully healed.

This treatment can affect how the heart works. You may have tests to check how well your heart is working. These may be done before, during and after treatment.

If the treatment is causing heart problems, your doctor may change the type of treatment you are having.

Contact the hospital straight away on the 24-hour number if you have any of these symptoms during or after treatment:

• breathlessness
• dizziness
• changes to your heartbeat
• swollen feet and ankles.

Other conditions can cause these symptoms, but it is important to get them checked by a doctor. 

Always call 999 if you have:

• chest pain, pressure, heaviness, tightness or squeezing across the chest
• difficulty breathing.

This treatment may affect the nerves in your fingers and toes. This can cause numbness, tingling or pain in your hands or feet. This is called peripheral neuropathy. You might find it hard to do fiddly tasks such as fastening buttons or tying shoelaces.

If you have these symptoms, always tell your doctor, nurse or pharmacist. They sometimes need to change the drug or the dose of the drug. The symptoms usually improve slowly after treatment ends. But for some people they continue and are a long-term side effect of treatment.

This treatment can affect how the kidneys work. This is usually mild and goes back to normal after treatment ends. You will have blood tests and may have a urine sample test to check how well your kidneys are working

Drinking fluids helps protect your kidneys. The advice is usually to try to drink at least 2 litres (3½ pints) of fluid each day. But follow any advice from your doctor, nurse or pharmacist about how much is right for you.

Contact the hospital on the 24-hour number if you: 

• have blood in your urine (pee) 
• have foamy, frothy or bubbly urine
• are passing less urine or peeing less often than usual.

Rarely, this treatment causes a brain condition that can be serious. You can make a full recovery from this. But it must be diagnosed and treated quickly.

This condition can cause:

• a headache that does not get better
• drowsiness or confusion
• changes in eyesight
• fits (seizures).

If you have any of these symptoms, it is important to either:

• contact the hospital straight away on the 24-hour number 
• go to the hospital straight away. 

You should not drive yourself to hospital.

We want everyone affected by cancer to feel our information is written for them.

We want our information to be as clear as possible. To do this, we try to:

• use plain English
• explain medical words
• use short sentences
• use illustrations to explain text
• structure the information clearly
• make sure important points are clear.

We use gender-inclusive language and talk to our readers as ‘you’ so that everyone feels included. Where clinically necessary we use the terms ‘men’ and ‘women’ or ‘male’ and ‘female’. For example, we do so when talking about parts of the body or mentioning statistics or research about who is affected.
