Has your doctor prescribed Ibrutinib to you or someone in your family? You probably have a lot of questions about this medication, especially since it comes in a liquid (suspension) form. You might be wondering things like, "What exactly does this do?", "What are the precautions?", "Are there any side effects?" Don't worry, it's normal. Let's talk about all of this simply and clearly.
Simply put, what is Ibrutinib?
Ibrutinib is a targeted therapy drug that controls the growth and spread of cancer cells. It is mainly used to treat cancers of the blood and lymphatic system, such as leukemia and lymphoma.
Imagine that cancer cells have a special messenger (a protein) that tells them to "divide and multiply." What Ibrutinib does is block the action of that messenger. Then the cancer cells lose the signal to grow. In this way, the spread of cancer cells is largely controlled.
In addition, this medicine is sometimes used to treat a specific reaction (chronic graft versus host disease) that can occur after a bone marrow transplant.

How should I use the medicine?
Since this is a liquid, it is very important to know exactly how to use it.
- Take as directed by your doctor: Take the dose prescribed by your doctor, at the same time every day. Taking it at the same time without changing the time will help you get better results.
- Shake well before use: Since this is a liquid, particles of the medicine may settle at the bottom of the bottle. Therefore, shake the bottle well before use.
- Use the correct measuring device: Only use the special oral syringe or measuring cup that comes with the medicine. Do not use household teaspoons or soup spoons, as they may not give an accurate measurement.
- Do not change the dose arbitrarily:If you experience side effects, your doctor may reduce your dose or stop taking the medicine for a while. But never stop taking the medicine or change the dose without your doctor's advice.
Very important: Do not eat grapefruit or drink grapefruit juice while taking this medicine. Also, do not eat Seville oranges. These fruits can interfere with the way the medicine works in your body.
What to do if you miss a dose of medication?
If you forget to take a dose, take it as soon as you remember. However, if it is almost time for your next dose (e.g., it is only a few hours away), skip the missed dose and take your next dose at the scheduled time. Do not take a double dose to make up for a missed dose.
What if I take too much medicine?
If you think you have taken too much medicine, don't panic. Immediately call the National Poisons Information Centre at the Colombo National Hospital. Or go to the Emergency Treatment Unit (ETU) of the nearest hospital.
