Regorafenib is a targeted cancer drug. You might have it as a treatment for:
- gastro intestinal stromal cancer (GIST) – a rare type of soft tissue sarcoma of the stomach or intestines
- advanced cancer that started in the liver (primary liver cancer)
How regorafenib works
Regorafenib is a type of targeted cancer drug called a cancer growth blocker. It works in two ways. It stops:
- signals that tell cancer cells to grow
- cancer cells forming new blood vessels, which they need to be able to grow
How you have regorafenib
Regorafenib are tablets you take once a day.
The usual dose is 4 tablets (160mg). But your doctor may change the dose.
You take regorafenib at the same time, each day. You swallow the tablets whole with a drink of water and after a low fat meal. A low fat meal means less than 30% fat.
Some examples of a low fat meal includes:
- 1 portion of cereal (about 30g)
- 1 glass of skimmed milk
- 1 slice of toast with jam
- 1 glass of apple juice
- 1 cup of coffee or tea
Taking your tablets
Speak to your pharmacist if you have problems swallowing the tablets.
Whether you have a full or an empty stomach can affect how much of a drug gets into your bloodstream.
You should take the right dose, no more or less.
Talk to your specialist or advice line before you stop taking a cancer drug.
When you have regorafenib
You usually take regorafenib every day, for 3 weeks. Then you have a week with no treatment. This 4 week period is called a cycle of treatment.
Then you start the cycle again.
Regorafenib may shrink the cancer or stop it growing for a time. You usually take regorafenib for as long as it is helping you and the side effects aren’t too bad.
You have blood tests before and during your treatment. They check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.
How often and how severe the side effects are can vary from person to person. They also depend on what other treatments you're having. For example, your side effects could be worse if you're also having other drugs or radiotherapy.
When to contact your team
Your doctor, nurse or pharmacist will go through the possible side effects. They will monitor you closely during treatment and check how you are at your appointments. Contact your advice line as soon as possible if:
- you have severe side effects
- your side effects aren’t getting any better
- your side effects are getting worse
Early treatment can help manage side effects better.
We haven't listed all the side effects here. Remember it is very unlikely that you will have all of these side effects, but you might have some of them at the same time.
Common side effects
These side effects happen in more than 10 in 100 people (more than 10%). You might have one or more of them. They include:
Increased risk of getting an infection
Increased risk of getting an infection is due to a drop in white blood cells. Symptoms include a change in temperature, aching muscles, headaches, feeling cold and shivery and generally unwell. You might have other symptoms depending on where the infection is.
Infections can sometimes be life threatening. You should contact your advice line urgently if you think you have an infection.
Breathlessness and looking pale
You might be breathless and look pale due to a drop in red blood cells. This is called anaemia.
Bruising, bleeding gums or nosebleeds
This is due to a drop in the number of platelets in your blood. These blood cells help the blood to clot when we cut ourselves. You may have nosebleeds or bleeding gums after brushing your teeth. Or you may have lots of tiny red spots or bruises on your arms or legs (known as petechiae).
Tiredness and weakness (fatigue)
Tiredness and weakness (fatigue) can happen during and after treatment - doing gentle exercises each day can keep your energy up. Don't push yourself, rest when you start to feel tired and ask others for help.
Soreness, redness and peeling on palms and soles of feet
The skin on your hands and feet may become sore, red, or may peel. You may also have tingling, numbness, pain and dryness. This is called hand-foot syndrome or palmar plantar syndrome.
Moisturise your skin regularly. Your doctor or nurse will tell you what moisturiser to use.
Loss of appetite and weight loss
You might not feel like eating and may lose weight. It is important to eat as much as you can. Eating several small meals and snacks throughout the day can be easier to manage. You can talk to a dietitian if you are concerned about your appetite or weight loss.
Contact your advice line if you have diarrhoea, such as if you've had 4 or more loose watery poos (stools) in 24 hours. Or if you can't drink to replace the lost fluid. Or if it carries on for more than 3 days.
Your doctor may give you anti diarrhoea medicine to take home with you after treatment. Eat less fibre, avoid raw fruits, fruit juice, cereals and vegetables, and drink plenty to replace the fluid lost.
Your voice might get husky or croaky and sound weaker. This can last for a while after your treatment.
High blood pressure
Tell your doctor or nurse if you have headaches, nosebleeds, blurred or double vision or shortness of breath. Your nurse will check your blood pressure regularly.
Mouth sores and ulcers
Mouth sores and ulcers can be painful. It helps to keep your mouth and teeth clean, drink plenty of fluids, avoid acidic foods such as oranges, lemons and grapefruits, and chew gum to keep the mouth moist. Tell your doctor or nurse if you have ulcers.
Skin problems include a skin rash, dry skin and itching. This usually goes back to normal when your treatment finishes. Your nurse will tell you what products you can use on your skin to help.
Feeling or being sick
Feeling or being sick is usually well controlled with anti sickness medicines. Avoiding fatty or fried foods, eating small meals and snacks, drinking plenty of water, and relaxation techniques can all help.
It is important to take anti sickness medicines as prescribed even if you don’t feel sick. It is easier to prevent sickness rather than treating it once it has started.
High levels of bilirubin
You might have high levels of bilirubin in your blood. You will have regular blood tests to check the bilirubin levels.
You may have some pain in your joints, arms and legs, or back. Tell your doctor or nurse if you have any pain. They can give medicine to help.
High temperature (fever)
If you get a high temperature, let your health care team know straight away. Ask them if you can take paracetamol to help lower your temperature.

Don’t have immunisations with live vaccines while you’re having treatment and for up to 12 months afterwards. The length of time depends on the treatment you are having. Ask your doctor or pharmacist how long you should avoid live vaccinations.
