1. Why am I using TRECONDI?

TRECONDI contains the active ingredient treosulfan. TRECONDI belongs to a group of medicines called alkylating agents.

TRECONDI is used as a treatment before blood stem cell transplantation in adults with blood cancers called acute myeloid leukaemia (AML) or myelodysplastic syndromes (MDS), and in adolescents and children older than one month with cancer found in the blood or bone marrow and non-cancerous disorders.

2. What should I know before I use TRECONDI?


Do not use TRECONDI if:

  • you are allergic to treosulfan,
  • if you suffer from an active uncontrolled infection,
  • if your heart, lung, liver or kidneys are not working properly
  • if you suffer from hereditary DNA repair disorder, a condition that reduces the ability to repair DNA (which carries your genetic information),
  • if you are pregnant, think you may be pregnant or are breastfeeding.

Check with your doctor if you:

  • have any other medical conditions
  • take any medicines for any other condition

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

TRECONDI may increase the risk of having another cancer in the future. You will have regular follow up with your doctor after treatment with TRECONDI is completed.

TRECONDI may cause symptoms of the menopause (absence of menstrual periods).


You must not receive live vaccines during treatment with treosulfan.

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant.

Talk to your doctor if you are breastfeeding or intend to breastfeed.

You must not get pregnant during treatment with this medicine and up to 6 months after treatment. Use an effective method of contraception when either you or your partner is receiving this medicine.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before you receive this medicine.

You should stop breast-feeding before starting treatment with this medicine and not breastfeed for at least 6 months after treatment.

If you are a man treated with this medicine, you should not father a child during and up to 6 months after treatment.

This medicine may make you infertile and it may not be possible for you to get pregnant after treatment with it. If you are concerned about having children, you should discuss this with your doctor before treatment. Men should seek advice about the possibility of sperm preservation before starting therapy.

Children and adolescents

Fits (seizures or convulsions) may occur very rarely in infants of less than 4 months of age. Children younger than 1 year may have more severe side effects that affect breathing. Your child will be monitored for signs of side effects affecting nerves and breathing problems.

Nappy rash with ulceration of the area around the anus (perianal) may occur in infants, toddlers and children wearing nappies because treosulfan passed out in the urine can damage the skin. Therefore, nappies should be changed frequently during 6–8 hours after each dose of this medicine. Skin should be kept clean and dry on days of treosulfan infusion to avoid rash or similar skin reactions.

There is not sufficient information on the use of treosulfan in children aged less than 1 month.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with TRECONDI and affect how it works.

TRECONDI may interfere with some medicines and affect how they work.

  • Digoxin, a medicine used for treatment of heart failure

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect TRECONDI.

4. How do I use TRECONDI?

How much to use

This medicine is used in combination with other chemotherapeutic agents. Your dose will be calculated by your doctor based on your body size (height and weight).

Your treatment with TRECONDI will be continuously supervised by an experienced doctor in a hospital or in a specialised centre for stem cell transplantation.

How TRECONDI is given

  • This medicine will be given to you by your doctor. It is given by drip (infusion) into a vein over 2 hours for 3 days before blood stem cell infusion.

If you forget to use TRECONDI

As you will be given this medicine by a doctor or a nurse it is unlikely that a dose will be missed. You must not be given a double dose to make up for a missed dose.

If you use too much TRECONDI

This medicine is given by a doctor or nurse. However, if you think you have received more of this medicine than you should, tell your doctor or nurse as soon as possible.

5. What should I know while using TRECONDI?

Things you should do

TRECONDI is a cell-killing (cytotoxic) medicine that is used to decrease the number of blood cells. At the recommended dose, this is the desired effect. You will have regular blood tests during treatment to check your blood cell counts do not fall too low.

Your doctor will monitor your blood liver enzymes regularly to check your liver is working normally.

In order to prevent and treat infections, you will be given medicines, such as antibiotics, antifungals or antivirals.

Since inflammation of the lining of the mouth is a common side effect of this medicine, you should pay attention to adequate oral hygiene. Preventative use of mouthwashes (e.g. with barrier protectants, antibacterial agents) or application of ice to the lining of the mouth (lessens blood flow to the lining of the mouth and reduces the amount of treosulfan reaching the healthy skin) is recommended.

Call your doctor straight away if you:

  • experience a fever (high temperature) while using TRECONDI

Remind any doctor, dentist, pharmacist or nurse you visit that you are using TRECONDI.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how TRECONDI affects you.

TRECONDI can cause nausea, vomiting and dizziness which may reduce your ability to drive or use machines. If you are affected, do not drive or use machines.

Drinking alcohol

Tell your doctor if you drink alcohol.

Your doctor will explain the risks associated with drinking alcohol before and after your treatment.

Looking after your medicine

This medication is cytotoxic and appropriate precautions must be taken when handling treosulfan. For this reason, your medicine will be handled and stored by trained personnel at the hospital.

TRECONDI is stored below 25°C.

Keep it where young children cannot reach it.

6. Are there any side effects?

All medicines can have side effects. If you do experience any side effects, most of them are minor and temporary. However, some side effects may need medical attention.

See the information below and, if you need to, ask your doctor or pharmacist if you have any further questions about side effects.

Your doctor will perform regular blood tests and other observations to check for blood counts, high sugar (glucose) levels in the blood, changes in the body’s ability to manage sugar (glucose), unusual amount of acid in the blood (acidosis /alkalosis), unusual amount of salts in the body, increased liver enzymes, increased C-reactive protein (a marker of inflammation in the body) and increased blood level of bilirubin. Your doctor will also check for signs of a second, unrelated cancer.
