Venclyxto is a cancer medicine that contains the active substance venetoclax. It belongs to a group of medicines called “BCL-2 inhibitors”.
Venclyxto is used to treat adults with:
CLL is a type of cancer affecting white blood cells called lymphocytes and the lymph nodes. In CLL, the lymphocytes multiply too quickly and live for too long, so that there are too many of them in the blood.
AML is a type of cancer affecting white blood cells called myeloid cells. In AML, myeloid blood cells multiply and grow very quickly in bone marrow and blood, so that there are too many of them and not enough red blood cells in the blood.
Venclyxto works by blocking a protein in the body called “BCL-2”. This protein is present in high amounts in some cancer cells and helps cancer cells survive. Blocking this protein helps to kill and lower the number of cancer cells. It also slows down the worsening of the disease.
It is important that you tell your doctor, pharmacist, or nurse about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Your doctor may need to stop certain medicines when you first start taking Venclyxto and during the first days or weeks when your dose is increased to the full standard dose.
Talk to your doctor, pharmacist, or nurse before taking Venclyxto if:
If any of the above apply to you, or you are not sure, talk to your doctor, pharmacist, or nurse before taking this medicine.
Some people may develop unusual levels of some body salts (such as potassium and uric acid) in the blood caused by the fast breakdown of cancer cells during treatment. This may lead to changes in kidney function, abnormal heartbeat, or seizures. This is called tumour lysis syndrome (TLS). The risk for TLS is in the first days or weeks of treatment with Venclyxto, as you increase your dose.
Your doctor, pharmacist or nurse will do blood tests to check for TLS.
Your doctor will also give you medicines to help prevent the build-up of uric acid in your body before you start treatment with Venclyxto.
Drinking plenty of water, at least 1.5 to 2 litres per day, helps to remove cancer cell breakdown products from your body through urine and may decrease your risk of getting TLS (see section 3).
Tell your doctor, pharmacist, or nurse immediately if you get any of the symptoms of TLS listed in section 4.
If you are at risk of TLS you may be treated in hospital so that you can be given fluids into the vein if needed, have blood tests done more often and to check for side effects. This is to see if you can continue to take this medicine safely.
You may be treated in hospital and your doctor or nurse will make sure that you have enough water/fluids, give you medicines to prevent the build-up of uric acid in your body and do blood tests before you start to take Venclyxto, while they increase your dose and when you start to take the full dose.
Venclyxto should not be used in children and adolescents. This is because it has not been studied in these age groups.
Tell your doctor or pharmacist if you take any of the following medicines as they can increase or decrease the amount of venetoclax in your blood:
Your doctor may change your dose of Venclyxto.
Tell your doctor if you take any of the following medicines as Venclyxto may affect how they work:
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines obtained without a prescription, herbal medicines and supplements. This is because Venclyxto may affect the way some other medicines work. Also, some other medicines can affect the way Venclyxto works.
Do not eat grapefruit products, Seville oranges (bitter oranges, often used in marmalades), or starfruit (carambola) while you are taking Venclyxto – this includes eating them, drinking the juice or taking a supplement that might contain them. This is because they can increase the amount of venetoclax in your blood.
Do not breast-feed while you are taking this medicine. It is not known whether the active substance in Venclyxto passes into breast milk.
Based on findings in animals, Venclyxto may cause male infertility (low or no sperm count). This may affect your ability to father a child. Ask your doctor for advice on sperm storage before starting treatment with Venclyxto.
You may feel tired or dizzy after taking Venclyxto, which may affect your ability to drive or use tools or machines. If this happens, do not drive or use any tools or machines.
This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially “sodium free”.
Always take this medicine exactly as your doctor, pharmacist, or nurse has told you. Check with your doctor, pharmacist, or nurse if you are not sure.
If you have CLL
You will begin treatment with Venclyxto at a low dose for 1 week. Your doctor will gradually increase the dose over the next 4 weeks to the full standard dose. For the first 4 weeks you will get a new pack each week.
Your dose may need to be adjusted for side effects. Your doctor will advise what your dose should be.
If you have AML
You will begin treatment with Venclyxto on a lower dose. Your doctor will gradually increase the dose each day for the first 3 or 4 days (depending on what medicine you take Venclyxto with). After 3 or 4 days you will take the full standard dose. The dose (tablets) is taken once a day.
Doses are listed in the table below
Day Venclyxto daily dose
1 100 mg (One 100 mg tablet)
2 200 mg (Two 100 mg tablets)
3 400 mg (Four 100 mg tablets)
4 and beyond 400 mg (Four 100 mg tablets) when you take Venclyxto in combination with azacitidine or decitabine
600 mg (Six 100 mg tablets) when you take Venclyxto in combination with cytarabine
Your doctor will give you Venclyxto in combination with another medicine (azacitidine or decitabine or low-dose cytarabine). You will keep taking Venclyxto at the full dose until either your AML gets worse or you cannot take Venclyxto as it is causing serious side effects.
If you vomit after taking Venclyxto, do not take an extra dose that day. Take the next dose at the usual time the next day. If you have problems taking this medicine, talk to your doctor.
Drink plenty of water
If you have CLL
It is very important that you drink plenty of water when taking Venclyxto during the first 5 weeks of treatment. This will help to remove cancer cell breakdown products from your blood through your urine.
You should start drinking at least 1.5 to 2 litres of water daily two days before starting Venclyxto. You may also include non-alcoholic and non-caffeinated drinks in this amount, but exclude grapefruit, Seville orange, or starfruit (carambola) juices. You should continue to drink at least 1.5 to 2 litres of water on the day you start Venclyxto. Drink the same amount of water (at least 1.5 to 2 litres daily) two days before and on the day that your dose is increased.
If your doctor thinks that you are at risk of TLS, you may be treated in the hospital so that you can be given extra fluids into the vein if needed, have your blood tests more often and be checked for side effects. This is to see if you can continue to take this medicine safely.
If you have AML
It is very important you drink plenty of water when taking Venclyxto especially when you start treatment and increase your dose. Drinking water will help to remove cancer cell breakdown products from your blood through your urine. Your doctor or nurse will give you fluids into the vein if needed if you are in hospital to make sure this happens.
If you take more Venclyxto than you should, talk to your doctor, pharmacist, or nurse or go to hospital immediately. Take the tablets and this leaflet with you.
Do not stop taking this medicine unless your doctor tells you to. If you have any further questions on the use of this medicine, ask your doctor, pharmacist, or nurse.

Tumour lysis syndrome (common – may affect up to 1 in 10 people)
Stop taking Venclyxto and seek medical attention immediately if you notice any of the symptoms of TLS:
Low white blood cell count (neutropenia) and infections (very common – may affect more than 1 in 10 people)
