All medicines have risks and benefits. Your doctor has weighed the risks of you taking LONSURF against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist for more advice.

What LONSURF is used for
LONSURF is a medicine used to treat cancer by slowing down the growth and spread of cancer cells.
LONSURF is used to treat adults with colon or rectal cancer – sometimes called ‘colorectal’ cancer.
It is also used to treat gastric cancer- sometimes called ‘stomach’ cancer.
- It is used when the cancer has spread to other parts of the body.
- It is used when other treatments have not worked – or when other treatments are not suitable for you.
LONSURF is a type of cancer chemotherapy which belongs to a group of medicines called ‘cytostatic antimetabolite medicines’.
LONSURF contains two different active substances trifluridine and tipiracil
- Trifluridine stops the growth of cancer cells.
- Tipiracil stops the trifluridine from being broken down by the body, helping trifluridine to work longer.
This medicine is available only with a doctor’s prescription.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
There is no evidence that LONSURF is addictive.

Do not take LONSURF if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.

Before you start to take it
Tell your doctor if you have allergies to:
- any other medicines
- any other substances, such as foods, preservatives or dyes
Tell your doctor if you are pregnant or intend to become pregnant. Like most anti-cancer medicines, LONSURF is not recommended for use during pregnancy. However, if you need to take LONSURF during your pregnancy, your doctor will discuss with you the benefits and risks of taking it.
You must not become pregnant while taking LONSURF, as this medicine may harm your unborn baby. You and your partner should use effective methods of contraception while taking this medicine. You should also do this for 6 months after you stop taking the medicine. If you or your partner becomes pregnant during this time, you must talk to your doctor or pharmacist straight away.
LONSURF may reduce fertility in both men and women. Your doctor will advise you of your options prior to starting treatment.
Do not breast-feed while taking LONSURF. Tell your doctor if you are breast-feeding or planning to breast-feed. This medicine may interfere with the growth and development of your baby.
Tell your doctor if you have or have had any medical conditions, especially the following:
- kidney problems
- LONSURF is not recommended in some patients with kidney problems. Before you start each treatment cycle of LONSURF, your doctor will perform blood tests to monitor your kidneys to see how they are working.
- liver problems.
- LONSURF is not recommended in some patients with liver problems. Before you start each treatment cycle of LONSURF, your doctor will perform blood tests to monitor your liver to see how your liver is working. Treatment with LONSURF may lead to a higher risk of liver problems.
If you have not told your doctor or pharmacist about any of the above, tell them before you start taking LONSURF.
Your doctor will carry out blood tests before each treatment cycle of LONSURF. They may also carry out other tests.
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop. LONSURF and other medicines may interact. These include medicines used for treatment of HIV, such as zidovudine. Zidovudine may not work as well if you are taking LONSURF.
You may need different amounts of your medicine, or you may need to take different medicines. Your doctor will advise you.
LONSURF contains lactose

MyLonsurf Dosing Calendar
The MyLonsurf dosing calendar has been created to help you understand your dose and treatment cycle. The MyLonsurf dosing calendar also contains important information on how many tablets of each strength you need to take for your current four week cycle.
Ask your doctor if you have not received, or have misplaced, your MyLonsurf dosing calendar.
How much to take
Your doctor or pharmacist will tell you how many tablets you will need to take each time. The dose depends on your weight and height and if you have kidney problems.
LONSURF comes in two strengths. Your doctor may prescribe both strengths for your prescribed dose.
You will take the dose two times a day – half the dose in the morning and half the dose at night.
How to take it
Swallow LONSURF tablets whole, with a glass of water.
Wash your hands after handling LONSURF tablets.
When to take it
Your doctor will usually prescribe LONSURF for 10 days during the first two weeks and then stop for two weeks. This two week on, two weeks off treatment period is one ‘cycle’ of treatment.
The specific dosing schedule is as follows:
- Week 1 – take the dose two times a day for five days. Then have two days off – no medicine.
- Week 2 – take the dose two times a day for five days. Then have two days off – no medicine.
- Week 3 – no medicine
- Week 4 – no medicine.
You will then begin another treatment cycle following the above pattern.
Take LONSURF immediately after your morning and evening meals, or within one hour after completion of your morning and evening meals.
How long to take it
Your doctor will continue to treat you with LONSURF as long as you are receiving benefit from therapy. Your doctor may need to reduce your dose or may decide to stop treatment if you experience serious side effects.
Do not stop taking it unless your doctor tells you to – even if you feel better.
If you do not understand the instructions provided, ask your doctor or pharmacist for help.
If you forget to take it
It is important that you take your prescribed dose as recommended by your doctor. If you have any questions or concerns about your medication, ask your doctor or pharmacist for help.
If you miss a dose, do not take the missed dose at a later date. Make a record of the dose you missed, and tell your Doctor and/or Pharmacist immediately.
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.
Tell your doctor or pharmacist about any missed dose.
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 (telephone 13 11 26 in Australia), or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much LONSURF. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much LONSURF it may make the side effects more severe, especially skin reactions (rash, blisters, redness, pain, swelling, itching or peeling of your skin).
