What Giotrif is used for
Giotrif contains the active substance afatinib (as afatinib dimaleate).
Giotrif belongs to a group of medicines called antineoplastic (or anti-cancer) agents.
It works by blocking the activity of a group of proteins from the ErbB family, which includes a protein called Epidermal Growth Factor Receptor (EGFR). These proteins are known to be involved in the growth and spread of cancer cells. By blocking the activity of these proteins Giotrif stops the cancer cells from growing and multiplying.
Giotrif is used to treat adult patients with a type of lung cancer called non-small cell lung cancer (NSCLC) identified with a change (mutation) in the EGFR (Epidermal Growth Factor Receptor) gene. Giotrif can be prescribed to you as initial cancer therapy or if your cancer has progressed after receiving chemotherapy.
Ask your doctor if you have any questions about why Giotrif has been prescribed for you. Your doctor may have prescribed Giotrif for another reason.
This medicine is available only with a doctor's prescription.

How to take Giotrif
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.
How much to take
The recommended dose is one tablet of Giotrif 40 mg each day.
Your doctor may adjust (increase or decrease) your dose in 10 mg steps depending on how well you tolerate Giotrif. If you get severe diarrhoea or other intolerable side effects, your doctor may interrupt your treatment with Giotrif and then re-start your treatment at a lower dose.
How to take it
Swallow the tablet whole with a full glass of water. Do not chew or crush the tablets.
For patients with swallowing difficulties the tablet can be dissolved in drinking water (non-carbonated). No other liquids should be used. Follow these instructions carefully:
- Drop the tablet into half a glass of drinking water (non-carbonated) (Do not break or crush the tablet)
- Stir the water occasionally for up to 15 minutes until the tablet is broken up into very small particles
- Drink the liquid straight away
- Rinse the empty glass with half a glass of drinking water and drink it.
When to take it
Take your medicine at about the same time each day. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
Take your medicine on an empty stomach. Do not eat for at least 3 hours before taking your medicine and at least 1 hour after taking your medicine. Food can interfere with the absorption of this medicine.
How long to take it
Continue taking your medicine for as long as your doctor tells you.
If you forget to take it
If it is less than 8 hours before your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (Australia telephone 13 11 26; New Zealand telephone 0800 764 766) for advice, or go to Emergency at the nearest hospital if you think that you or anyone else may have taken too much Giotrif. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
While you are taking Giotrif
Things you must do
If you are about to be started on any new medicine, tell your doctor or pharmacist that you are taking Giotrif.
Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.
If you go into hospital, tell the medical staff that you are taking this medicine.

Things to be careful of

Be careful driving, operating machinery or doing jobs that require you to be alert until you know how Giotrif affects you. No studies on the effects of Giotrif on the ability to drive and operate machinery have been performed.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Giotrif.
All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if you notice any of the following and they worry you:
- skin reactions such as acne-like rash, sometimes itchy with dry skin
- mouth sores and inflammation
- problems with your nails
- loss of appetite or weight changes

Giotrif may be associated with changes in your blood, urine or liver test results. Your doctor may want to perform tests from time to time to check on your progress and detect any unwanted side effects.
Tell your doctor immediately if you notice any of the following:
- diarrhoea (usually occurs within the first 2 to 6 weeks of treatment)
- any signs and symptoms of dehydration such as headache, dizziness, tiredness or decreased urine output
- severe skin reactions such as peeling or blistering of the skin
- sudden or worse eye problems such as irritated, red, runny or itchy eyes, blurred vision, swollen or crusty eyelid, or dry eye
- a combination of any of the following: breathlessness, swelling of the feet, ankles, legs or stomach, feeling tired, a feeling like your heart is racing or throbbing.
Diarrhoea is a very common side effect of Giotrif and this is sometimes severe. You may become dehydrated if you experience severe or persistent diarrhoea and this could become serious and life-threatening if untreated.
As soon as you notice any signs of diarrhoea, you should drink plenty of fluids and take the anti-diarrhoeal medicine exactly as your doctor tells you to help treat your diarrhoea.
You must immediately ask your doctor for further advice if your diarrhoea becomes severe (with more than 4 bowel movements each day) or if your diarrhoea is not under control within 48 hours after taking the anti-diarrhoeal medicine.
Tell your doctor immediately or go to Emergency at your nearest hospital if you experience sudden difficulty in breathing or unexplained breathing problems associated with cough or fever. Some patients taking Giotrif have experienced a rare form of lung inflammation called interstitial lung disease which is a serious side effect. This side effect is uncommon. You may need urgent medical attention or hospitalisation.
Tell your doctor immediately or go to Emergency at your nearest hospital if you experience:
- severe upper stomach pain radiating to the back, nausea, vomiting, or fever (which may be symptoms of an inflamed pancreas - pancreatitis)
- severe blisters and bleeding in the lips, eyes, mouth, nose and genitals
- painful red areas of the skin, large blisters and peeling of the skin, accompanied by fever and chills, aching muscles and generally feeling unwell.
These side effects are uncommon. You may need urgent medical attention or hospitalisation.
Tell your doctor or pharmacist if you notice anything else that is making you feel unwell. Other side effects not listed above may also occur in some people.

Keep your tablets in the blister pack until it is time to take them to protect from moisture and light. If you take the tablets out of the blister pack they may not keep well.
