Taking VENCLEXTA
YOUR TREATMENT JOURNEY WITH VENCLEXTA
Before VENCLEXTA treatment begins:
- It’s important you stay well hydrated when taking VENCLEXTA.
- Make sure you drink plenty of water (6 to 8 glasses or 1.5 to 2 L per day) as instructed, throughout your treatment with VENCLEXTA, especially at the start of your treatment and every time your dose is increased during the gradual dose-increase phase.
- If you are in hospital, you might receive hydration through a drip.
- If your doctor has requested that you take other medications prior to VENCLEXTA, follow your doctor’s instructions on how to take them.
Importance of blood tests
VENCLEXTA breaks down the cancer cells in your body. As a result, there can be some changes to your blood chemistry that are important to monitor. Your healthcare team will arrange blood tests for you before you start VENCLEXTA and during the initial stages of treatment. It is important you keep to all your scheduled appointments.
What happens during treatment?
Depending on what your doctor advises, your treatment with VENCLEXTA will be either entirely as an outpatient (at home or in the day-stay unit at the hospital), or start as an inpatient in hospital with a transition to treatment at home. For your first few days of treatment your healthcare team will closely monitor how your treatment is working. One of the ways they do this is by taking blood tests.
It’s important to keep an eye on how you’re feeling so you can let your healthcare team know if you’re experiencing any side effects.

Do not take VENCLEXTA if you are allergic to VENCLEXTA or any other ingredients in the product. Talk to your doctor or pharmacist if you are unsure.
Tumor Lysis Syndrome (TLS):
TLS is caused by the rapid breakdown of cancer cells resulting in high levels of certain chemicals and low levels of calcium circulating in the blood. This situation can cause serious damage to the kidneys as well as other organs in the body.
The risk for TLS is usually the highest in the first days of treatment with VENCLEXTA, as you increase your dose.
To help prevent TLS, it is important to stay hydrated and drink water every day when taking VENCLEXTA.
Keep all your appointments, including those for your blood tests, since the changes in your blood that can lead to TLS may not have any symptoms until the situation becomes very serious. Take any additional medicines your doctor may prescribe to help prevent TLS.
It is recommended that you drink 6 to 8 glasses (approximately 1.5 to 2 litres total) of water each day, starting two days before and on the day of your first dose of VENCLEXTA, and every time the dose is increased.
TAKING VENCLEXTA
Starting Treatment
- Your healthcare team will start you on a low dose of VENCLEXTA and increase it each day until you reach your recommended dose
(also called the dose increase or dose titration phase). - You will have blood tests before and after each dose during the dose increase phase to monitor how your body is reacting.
- Your recommended dose depends on a number of things, including whether you are taking any other medicines, have any other health conditions and how you react to the treatment.
- Once you have reached your recommended dose, and your healthcare team is happy for you to do so, you will be able to continue VENCLEXTA treatment at home.
You should take VENCLEXTA as advised by your healthcare team at the prescribed dose. Do not change your dose or stop taking VENCLEXTA unless your healthcare team tells you to do so.
Two days before you start taking VENCLEXTA, drink at least 6 to 8 glasses of water each day and continue to do this throughout your treatment, especially each time your dose is increased.
This includes:
- Eating them (including jams or marmalades)
- Drinking their juice
- Taking supplements that might contain them
They can increase the effect of VENCLEXTA in your body.
Staying Hydrated
It is important to stay hydrated when taking VENCLEXTA and drink about 6 to 8 glasses (1.5 to 2 litres) of water each day as instructed.
Make especially sure you drink your 6-8 glasses of water on these days:
- The two days before, and the day that you take your first VENCLEXTA dose
- The two days before, and the day you increase your VENCLEXTA dose.

IMPORTANT INFORMATION ABOUT VENCLEXTA®
VENCLEXTA® is a prescription medicine containing venetoclax. Venclexta is available as film-coated tablets of various strength (10 mg, 50 mg, 100 mg venetoclax). It is used to treat adults with chronic lymphocytic leukaemia (CLL) or small lymphocytic lymphoma (SLL) or acute myeloid leukemia (AML). Venclexta is taken alone or in combination with other medicines. Your doctor will let you know which combination medicines, how to take them, and how long to take them. Typically, you will start treatment with Venclexta at a low dose. If you are taking Venclexta for CLL or SLL, your doctor will gradually increase your dose over 5 weeks up to the full dose. If you are taking Venclexta for AML, your doctor will gradually increase your dose up to the full dose over 3, or 4 days, depending on the combination medicine used. Use strictly as directed by your doctor. Venclexta has risks and benefits. You must not take it if you are allergic to venetoclax or to any of the inactive ingredients. For CLL or SLL, do not take Venclexta if you are taking any of the following medicines: medicines used to treat or prevent fungal infections, including ketoconazole, posaconazole, voriconazole, itraconazole; clarithromycin (an antibiotic); or ritonavir (a medicine used to treat HIV and hepatitis C).

Do not stop using Venclexta or change the dose without checking with your doctor. Venclexta can cause tumour lysis syndrome (TLS) , which is caused by the fast breakdown of cancer cells. TLS is a very serious side effect that can be fatal. TLS is most likely to occur when you are first starting treatment. To help prevent TLS, it is important to stay hydrated and drink water every day when taking Venclexta. Particularly, starting two days before and on the day of your first dose of Venclexta and every time the dose is increased, drink 6 to 8 glasses (approximately 1.5-2 L total) of water each day. Let your healthcare provider know immediately if you experience: fever or chills; feeling sick or vomiting; being short of breath; feeling unusually tired; changes in your heart rate (slow, fast or irregular); your urine looks dark or cloudy; feeling confused; convulsions or fits; or pain in the muscles or joints while on treatment with Venclexta. Ensure you follow all your doctor’s instructions carefully and keep all your appointments, including those for blood tests. You may experience a low number of neutrophils, a type of white blood cells – this can be severe and need treatment. Your doctor will check your blood counts during treatment with Venclexta. You may experience infections during treatment with Venclexta. Some infections can be very serious or even fatal. Your doctor will closely monitor and treat you right away if you have fever or any signs of infection during treatment with Venclexta.
