Frequently asked questions
Let’s begin.
1. What Is Blood Cancer?
Blood cancer is a disease where blood cells grow in an uncontrolled way. Instead of working normally, these cancer cells take over healthy cells and stop your body from working properly.
There are different types of blood cancer, including:
a. Chronic Myeloid Leukemia (CML)
CML is a type of cancer that affects white blood cells. These are the cells that help your body fight infections. In CML, your body makes too many abnormal white blood cells that crowd out healthy ones.
b. Acute Lymphoblastic Leukemia (ALL)
ALL is another fast-growing cancer of the blood and bone marrow. It usually affects children but can also occur in adults.
c. Gastrointestinal Stromal Tumors (GISTs)
These are not blood cancers but are soft tissue tumors that also respond to Imatib.
Among these, CML is the most common type treated with Imatib 400 mg.
2. What Is Imatib 400 mg?
Imatib 400 mg is a tablet that contains the medicine Imatinib Mesylate. This is a targeted therapy, meaning it works specifically on cancer cells without harming most of the normal cells in your body.
Imatib belongs to a group of medicines called tyrosine kinase inhibitors (TKIs). It is often used as the first-line treatment for patients with CML and some other cancers.
It is available in tablet form and is taken by mouth, usually once a day.
3. How Does Imatib 400 mg Work?
To understand how Imatib works, let’s first understand the cause of CML.
a. The Role of the Philadelphia Chromosome
In most people with CML, the cause is a genetic change called the Philadelphia chromosome. This abnormal chromosome produces a harmful protein called BCR-ABL. This protein tells cells to grow too fast and avoid normal death — this leads to cancer.
b. Imatib Blocks the BCR-ABL Protein
Imatib 400 mg works by blocking the BCR-ABL protein. When this protein is blocked, the cancer cells stop growing and may even die. It does not cure the disease, but it controls it and keeps it from getting worse.
Imatib is like a switch that turns off the cancer signal inside your cells.
4. Who Can Take Imatib 400 mg?
Imatib is mainly given to:
Adults and children with Chronic Myeloid Leukemia (CML)
Adults with Acute Lymphoblastic Leukemia (ALL) that is Philadelphia chromosome positive
Adults with Gastrointestinal Stromal Tumors (GISTs)
Patients with certain rare blood disorders
Your doctor will decide if Imatib is right for you after doing blood tests, bone marrow tests, and sometimes genetic tests.
5. How to Take Imatib 400 mg
Taking Imatib correctly is very important for it to work well.
a. Dosage
The usual dose is 400 mg once a day.
Some patients may need a higher dose, like 600 mg or 800 mg, based on their condition.
Children may be given a different dose depending on their weight and condition.
b. How to Take It
Take the tablet with a meal and a full glass of water. This helps avoid stomach upset.
Swallow it whole — do not crush, break, or chew the tablet.
Try to take it at the same time every day to help you remember.
c. If You Miss a Dose
Take it as soon as you remember.
If it is almost time for your next dose, skip the missed dose.
Do not take two doses at the same time.
6. What Are the Common Side Effects of Imatib 400 mg?
Like all medicines, Imatib can have side effects. Not everyone gets them, and most are mild or manageable.
a. Common Side Effects
Nausea or vomiting
Diarrhea
Swelling of hands, feet, or around the eyes
Muscle cramps
Tiredness
Skin rash
b. Serious Side Effects
Low blood cell counts (anemia, low platelets, low white cells)
Liver problems
Bleeding or bruising easily
Shortness of breath or chest pain
Severe stomach pain
If you notice any serious symptoms, call your doctor right away.
7. What Tests Are Needed While Taking Imatib?
Your doctor will check your health regularly while you are on Imatib.
You may need:
Blood tests – to check your blood cell counts and liver/kidney function.
Bone marrow tests – to see how the cancer is responding.
Molecular tests (PCR) – to check if the BCR-ABL gene is still active.
Imaging tests – like CT scans if you have GISTs.
These tests help your doctor know if the medicine is working and if it's safe to continue.
8. Tips to Take Imatib Safely
Here are some things to remember:
Take it with food and water.
Don’t skip doses. If you forget too often, it may not work well.
Keep regular appointments with your doctor.
Tell your doctor about any other medicines you take. Some drugs can interact with Imatib.
Avoid grapefruit juice, as it may affect how the medicine works.
Don’t stop taking Imatib unless your doctor tells you to.
9. Can Imatib Cure CML?
Imatib does not cure CML in most cases. However, it can:
Control the disease for many years
Help people live a normal or near-normal life
Reduce the number of cancer cells to very low or undetectable levels
Some patients who respond very well for many years may be able to stop treatment under close medical supervision — but this decision is made very carefully.

10. What If Imatib Stops Working?
Sometimes, Imatib may stop working if the cancer becomes resistant to it. In such cases, your doctor may:
Increase the dose
Switch you to another TKI (like Dasatinib, Nilotinib, or Ponatinib)
Do more tests to check for new mutations
Early action helps manage resistance better.
11. Life with Imatib: What to Expect
Most people on Imatib can work, travel, and live a normal life with a few adjustments. Here are some helpful tips:
a. Eat Healthy
Eat a balanced diet with fruits, vegetables, and protein to stay strong.
b. Stay Hydrated
Drink plenty of fluids, especially if you have side effects like diarrhea.
c. Protect Your Skin
