Venetoclax for cancer treatment: Let's talk about this drug in simple terms!

Has your doctor prescribed Venetoclax for a cancer condition? If so, it is very important to be fully informed about this medicine. Because this is a very powerful, specialized medicine. Today, we will talk very simply and politely about what this medicine is and what you need to be careful about when using it.

What kind of medicine is this? (What is Venetoclax?)

Simply put, Venetoclax is a "targeted therapy." This means that this drug very cleverly targets specific proteins in cancer cells, stopping or killing them from growing. It works in a different way than regular chemotherapy.

This medicine is mainly used to treat blood-related cancers such as:

• Chronic Lymphocytic Leukemia (CLL)
• Small Lymphocytic Lymphoma (SLL)
• Acute Myelogenous Leukemia (AML)

Your doctor may also recommend this medicine for other medical conditions.

Things you need to tell your doctor before starting medication

Before starting Venetoclax, it is very important to give your doctor a complete description of your health condition. Be sure to tell your doctor if you have any of these conditions:

• Kidney or liver disease: If you have any kidney or liver disease.
• Blood abnormalities: If the level of uric acid in the blood is elevated, or if the levels of salts such as potassium, phosphorus, and calcium are low or high.
• Gout: If you have gout.
• If you are scheduled to receive a vaccine: If you are planning to receive a vaccine soon, especially a live virus vaccine.
• Allergies: If you have an allergy to Venetoclax or any other medicine, food, or dye.
• Pregnancy: If you are pregnant, trying to get pregnant, or suspect you are pregnant.
• If you are a nursing mother: If you are breastfeeding your baby.

Based on this information, your doctor will decide on the dosage of the medicine you will be given, the method of administration, and the precautions you should take.

How exactly do I use this medicine?

This is a very important part. Follow these instructions to get the most out of the medicine and minimize side effects.

• Take with food: Always take this tablet with a meal and a glass of water. Do not take on an empty stomach.
• Swallow the tablet: Do not break, crush, or chew the tablet. Swallow it whole.
• Do not eat these fruits: Do not drink grapefruit juice, eat Seville oranges, or starfruit while taking this medication. These can change the way the medication works in the body.
• Take it on time: Try to take your medicine at the same time every day. Do not take more than the amount your doctor prescribes.
• Do n't stop taking your medication without your doctor's advice for any reason .

What do you do if you miss a medication appointment?

Imagine you forgot to take your medicine.

• If it is more than 8 hours since you last took the pill when you remember, take it as soon as you remember.
• However, if it's been more than 8 hours since you last took a dose, skip the missed dose. Take your pill at your regular time the next day.
• Never take a double dose.
• If you vomit after taking the medicine, do not take another pill. Take the usual dose at the scheduled time the next day.

Things to be especially careful about when taking Venetoclax

You need to pay a little more attention to your body while taking this medicine.

• Tumor Lysis Syndrome (TLS) Risk: This is a bit of a complicated term, but it's simple: When Venetoclax rapidly destroys cancer cells, the contents of those cells suddenly leak into the bloodstream. This can affect the kidneys. Your doctor will likely prescribe other medications before you start taking the drug to prevent this.
• Drink plenty of water: One of the best ways to reduce the risk of TLS is to drink plenty of water throughout the day. You should drink the amount of water your doctor recommends (usually 1.5 - 2 liters per day).
• Blood tests: While taking this medication, your doctor will order blood tests to check your blood cell count and kidney function regularly. Don't skip these tests.
• Protect yourself from infections: This medicine can lower your body's immunity. That means you are more likely to get sick. So stay away from people who have a fever or cold. If you develop symptoms like fever, cough, or sore throat, do not self-medicate and inform your doctor immediately .
• Pregnancy and breastfeeding: Avoid becoming pregnant while taking this medicine and for 30 days after stopping it. Also, avoid breastfeeding while taking this medicine and for one week after stopping it. Ask your doctor for more information about this.

What are the possible side effects of this medicine?

Like any medicine, Venetoclax can cause some side effects. Some of these are serious, while others are common. The important thing is to be aware of these symptoms and take action quickly if necessary.

If you experience any other unusual symptoms not mentioned in this list, talk to your doctor about them as well.

Other things that may interact with this medicine

Venetoclax can interact with other medications, herbal remedies, and some foods. So tell your doctor about everything you're taking —including prescription medications, over-the-counter medications, vitamins, herbal remedies, and supplements. It's especially important to tell your doctor if you're taking any of the following medications:

• Antifungal medications (e.g. Ketoconazole, Fluconazole)
• Some antibiotics (e.g. Clarithromycin, Erythromycin)
• Some medications for high blood pressure and heart disease (e.g. Diltiazem, Verapamil, Carvedilol)
• Anticonvulsant medications (e.g. Carbamazepine, Phenytoin)
• Herbal products such as St. John's wort

How do you store and dispose of medication?

• Storage: Keep out of reach of children and pets. Store in the original container, tightly closed, away from moisture and excessive heat, at room temperature (below 30 degrees Celsius).
• Disposal: The safest way to dispose of expired or unwanted medications is to take them to a medication take-back program at your hospital or pharmacy. If that is not possible, remove the pills from the bottle, mix them with something like used coffee grounds, cat litter, or soil, put them in a sealable bag, and throw them in the trash. Never flush them down the toilet.
