Afatinib (Giotrif®)
Afatinib (Giotrif®) is a targeted therapy drug used to treat some types of lung cancer.
What is afatinib?
Afatinib (Giotrif®) is a type of targeted therapy drug used to treat non-small cell lung cancer (NSCLC). Afatinib may also be used to treat other cancers as part of a clinical trial.
It is best to read this information with our general information about targeted therapy and the type of cancer you have.
Afatinib is used if tests show the cancer cells have a genetic change called EGFR (EGFR-positive) and if the cancer has spread to:
- surrounding tissues (locally advanced)
- other parts of the body (advanced or metastatic).
Your cancer team will talk to you about this treatment and its possible side effects before you agree (consent) to have treatment.
More information about this treatment
This information is correct at time of publishing. But sometimes the types of cancer this treatment is used for, or treatment side effects, may change between revision dates.
You can talk to your cancer team if you want more detailed information about this treatment. Or visit the electronic Medicines Compendium (eMC) website, which has patient information leaflets (PIL) for individual drugs.
How afatinib is given
Afatinib comes in tablets. This means you can take them at home. You may have it with other cancer drugs.
During your course of treatment, you will meet with someone from your cancer team, such as a:
- cancer doctor
- chemotherapy nurse or specialist nurse
- specialist pharmacist.
This is who we mean when we mention doctor, nurse or pharmacist in this information.
During your course of treatment, you will have regular blood tests. This is to check that it is safe for you to have treatment.
You will meet with a doctor, nurse or pharmacist before you have treatment. They will talk to you about your blood results and ask how you have been feeling. If your blood results are okay, the pharmacy team will prepare your targeted therapy.
Your course of treatment
Your cancer team will discuss your treatment plan with you. They will give you the tablets to take home. They may give you tablets of different strengths. Always take them exactly as they tell you to. This is important to make sure they work as well as possible for you.
You usually take afatinib for as long as it is controlling the cancer and your side effects can be managed. Do not stop taking your tablets unless your doctor tells you to.
Your cancer team may also give you anti-sickness drugs and other medicines to take home. Take all your capsules or tablets exactly as they tell you to.
Taking afatinib tablets
You take afatinib as a tablet once a day. Afatinib should be taken without food, as this makes it less effective.
Make sure you:
Other things to remember about your tablets:
- wait for at least 3 hours before taking the tablets, if you have already eaten
- don’t eat for at least 1 hour after taking the tablets
- swallow them whole with a glass of water
- do not chew, break or crush them
- take them at the same time every day.
If you have trouble swallowing tablets, ask your pharmacist for advice. They can explain what to do.
If you forget to take a tablet and the scheduled dose is more than 8 hours away, you can take the missed dose.
If the next scheduled dose is due within 8 hours, then skip the missed dose and take your next dose at the usual time. Do not take a double dose. Contact the hospital on the 24-hour number you have been given for advice.
Other things to remember about your tablets:
- Wash your hands after taking them.
- Other people should avoid direct contact with them.
- Keep them in the original package and at room temperature, away from moisture, heat and direct sunlight.
- Keep them safe, where children cannot see or reach them.
- If you are sick (vomit) just after taking them, do not take an extra dose. Take your next dose at the usual time.
- Do not throw away unused capsules or tablets. Return them to your cancer team at the hospital.
Lactose
This treatment may contain lactose. If you have a lactose allergy or intolerance, ask your doctor, nurse or pharmacist for more information.
About side effects
We explain the most common side effects of this treatment here. We also include some that are less common.
You may get some of the side effects we mention, but you are unlikely to get all of them. And you may have some side effects, including rarer ones, that we have not listed here.
Other cancer treatments may cause different side effects. If you are also having other cancer treatment, you may have other side effects.
Always tell your doctor, nurse or pharmacist about any side effects you have. They can give you:
- drugs to help control some side effects
- advice about managing side effects.
It is important to take any drugs exactly as explained. This means they will be more likely to work for you.
Serious and life-threatening side effects
Some cancer treatments can cause serious side effects. Sometimes, these may be life-threatening. Your doctor, nurse or pharmacist can explain the risk of these side effects to you.
Contact the hospital
Your doctor, nurse or pharmacist will give you 24-hour contact numbers for the hospital. If you feel unwell or need advice, you can call at any time of the day or night. Save these numbers in your phone or keep them somewhere safe.
Very common side effects
Diarrhoea
This treatment may cause diarrhoea. It usually starts in the first 2 weeks of treatment.
Diarrhoea means passing more stools (poo) than is normal for you, or having watery or loose stools. If you have a stoma, it will be more active than usual.
Your doctor, nurse or pharmacist may give you anti-diarrhoea drugs to take at home.
If you have diarrhoea or a mild increase in stoma activity, follow their advice about:
- taking anti-diarrhoea drugs
- how much and what type of fluids to drink
- any changes to your diet that might help.
Contact the hospital straight away on the 24-hour number if:
- you have diarrhoea at night
- you have uncomfortable stomach cramps
- you have diarrhoea 4 or more times in a day
- you have a moderate increase in stoma activity
- the anti-diarrhoea drugs do not work within 24 hours.
You may need to give a stool sample, or go to hospital to have fluids through a drip or antibiotics.
If you have diarrhoea, your doctor may need to stop your treatment or lower the dose for a while.
Skin changes
Afatinib can affect your skin. It may cause an acne-like rash on your head, chest and back. This usually begins in the first 2 to 3 weeks of treatment. Your skin may also:
- become dry and itchy
- feel tender and peel.
If you develop skin changes, let your doctor know straight away. They can prescribe treatment to help.
The following things may help:
- Use tepid water and mild, non-scented soap.
- Avoid skincare products containing alcohol.
- Do not use anti-acne products.
- Moisturise your skin regularly and especially after a bath or shower.
A rash may get worse if exposed to the sun. You should protect your skin in the sun by:
- using a sun cream with a high sun protection factor (SPF) of at least 30
- covering up with clothing and a hat.
If you are having radiotherapy, do not put sun cream on the area being treated.
Sore mouth and throat
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.
Feeling sick
Your doctor, nurse or pharmacist will prescribe anti-sickness drugs to help prevent or control sickness. Take the drugs exactly as they tell you to, even if you do not feel sick. It is easier to prevent sickness than to treat it after it has started.
If you feel sick, take small sips of fluid often and eat small amounts regularly. It is important to drink enough fluids. If you continue to feel sick, or if you are sick (vomit) 1 to 2 times in 24 hours, contact the hospital on the 24-hour number as soon as possible. They will give you advice. They may change your anti-sickness treatment. Let them know if you still feel sick.
Loss of appetite
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.
Tummy pain
You may get pain in your tummy (abdomen), or have indigestion. Your doctor, nurse or pharmacist can give you advice or treatment to help. Contact the hospital straight away on the 24-hour number if your symptoms do not go away, or get worse.
Nosebleeds
Other side effects
Serious skin changes
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.
Bladder irritation
Your bladder may feel irritated during treatment. You may notice a burning feeling when you pass urine (pee). Or you may need to pee more often or more urgently (cystitis). If you have these symptoms, tell your nurse or doctor. They can check your urine to see if you have an infection. Drinking around 2 litres (3½ pints) of fluids per day can help reduce irritation.
Effects on the eyes
Your eyes may become watery and feel dry or sore. Your doctor, nurse or pharmacist can give you advice and eye drops to help with this.
Contact the hospital on the 24-hour number if:
- your eyes get red and inflamed (conjunctivitis)
- you have pain in your eyes
- you notice any change in your vision.
If your eyesight is affected or you find it difficult to concentrate, do not drive or use machinery.
Nail changes
This treatment can affect your nails. They may grow more slowly or break more easily. You might notice ridges or white or dark lines across your nails. These changes usually disappear as the nails grow out after treatment. Sometimes nails can become loose or fall out.
If the skin around your nails becomes sore and swollen, contact the hospital straight away on the 24-hour number. These might be signs of an infection.
Tips to look after your nails:
- Keep your nails clipped short and clean.
- Avoid using very hot water when washing your hands or bathing.
- Moisturise your nails and cuticles regularly.
- It is okay to use water-based nail polish - but ask your cancer team if you want to use false nails, gels or other acrylics during treatment.
- Wear gloves to protect your nails when working in the house or garden.
- If your toenails are affected, wear well-fitting shoes, or shoes with open toes to cushion them.
Tell your doctor or nurse about any changes to your nails. They can give you advice or arrange for you to see a podiatrist. They are a foot care specialist.
Hand-foot (palmar-plantar) syndrome
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.
Effects on the liver and kidneys
This treatment can affect how your kidneys or liver work. This is usually mild and goes back to normal after treatment ends. You will have blood tests to check how well your kidneys and liver are working. Contact the hospital on the 24-hour number if you:
- have blood in your urine (pee)
- are passing less urine or peeing less often than usual.
Drinking fluids also 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.
Effects on the lungs
This treatment can cause changes to the lungs. Tell your doctor, nurse or pharmacist if you develop:
- a cough that does not go away
- wheezing
- breathlessness.
You should also tell them if any existing breathing problems get worse. You may have tests to check your lungs.
Changes to your taste
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.
Other information
Blood clot risk
Cancer and some cancer treatments can increase the risk of a blood clot. Contact the hospital straight away on the 24-hour number if you have any of these symptoms during or after treatment:
- throbbing pain or swelling in a leg or arm
- reddening of the skin in the area – if you have black or brown skin, this can be harder to notice, but the skin might become darker
- suddenly feeling breathless or coughing.
Always call 999 if you have:
- chest pain
- difficulty breathing.
A blood clot is serious, but it can be treated with drugs called anticoagulants. These thin the blood. Your doctor, nurse or pharmacist can give you more information about preventing and treating blood clots.
Other medicines
Some medicines can affect how this treatment works or be harmful while you are having it. Always tell your cancer doctor, nurse or pharmacist about any drugs you are taking or planning to take, such as:
- medicines you have been prescribed
- medicines you buy in a shop, pharmacy or online
- vitamins or supplements
- herbal drugs and complementary or homeopathic therapies
- recreational drugs – for example, cannabis.
Vaccinations
Doctors usually recommend that people with cancer have vaccinations for flu and for coronavirus (covid). These help reduce your risk of serious illness from these infections. Most people can have these vaccines, including people with weak immune systems.
If your immune system is weak, you should not have live vaccinations. Live vaccines can make you unwell because they contain a very weak version of the illness they will protect you against. Live vaccines include Zostavax®, which is a shingles vaccine, and the yellow fever vaccine.
It is important to ask your doctor, nurse or pharmacist for advice about having vaccinations. They can explain what vaccines are right for you and when it is best to have them.
Contraception
Your doctor, nurse or pharmacist will advise you not to get pregnant or make someone pregnant while having this treatment and for some time afterwards. The drugs may harm a developing baby. It is important to use contraception to prevent pregnancy. Follow their advice about:
- what types of contraception to use
- how long after treatment you should continue to use contraception.
Breastfeeding
You are advised not to breastfeed while having this treatment, or for some time after treatment ends. This is because the drugs could be passed to the baby through breast milk.
Your doctor, nurse or pharmacist can give you more information.
Fertility
Some cancer drugs can affect whether you can get pregnant or make someone pregnant. If you are worried about this, it is important to talk with your doctor before you start treatment.
Medical and dental treatment
If you need medical treatment for any reason other than cancer, always tell the healthcare professional that you are having cancer treatment. Give them the contact details for your cancer doctor or cancer team so they can ask for advice.
If you have appointments with a dentist, always tell them you are having cancer treatment. Talk to your cancer team before you have any dental treatment.
