Have you been prescribed Fedratinib? You must know these things (Fedratinib Capsules)

It's normal to feel a little scared and nervous when starting a cancer treatment. Fedratinib is a special drug given for this type of cancer . So it's very important that you have a clear understanding of this drug, how it works, and what it can do. Let's talk about all of this in a simple way that you can understand.

What kind of medicine is Fedratinib?

Simply put, Fedratinib is a drug used to treat a type of bone marrow cancer. The bone marrow inside our bones is like a factory that makes our blood cells (red cells, white cells, and platelets ). In some types of cancer, the process in this factory goes awry.

This drug works by blocking the action of a specific protein that helps cancer cells grow, divide, and multiply. It's like turning off a switch that keeps cancer cells alive. This stops the spread of cancer cells and helps control the disease.

You may find this medicine at the pharmacy under the brand name INREBIC .

Things you need to tell your doctor before starting medication

Your doctor will ask about your complete health history before deciding to give you this medicine. However, sometimes we forget things. So, if you have any of the following, be sure to tell your doctor about it.

  • Previous blood clots: If you have had a blood clot in your leg, lung, or elsewhere.
  • Other Cancers: This refers to any cancer other than bone marrow cancer.
  • Heart attack or heart disease : If you have had a heart attack before or have other heart disease.
  • Kidney disease : If there is any impairment in the functioning of the kidneys.
  • Liver disease : If you have any liver disease.
  • Low blood cell count: If your blood tests show a low white blood cell , platelet, or red blood cell count.
  • Thiamine (Vitamin B1) Deficiency: If you have previously been diagnosed with a vitamin B1 deficiency.
  • Stroke: If you have had a previous stroke.
  • Tobacco use: If you are a smoker.
  • Allergies: If you are allergic to any other medicine, food, or dye, not just to Fedratinib.
  • Pregnancy: This is very important if you are pregnant or planning to become pregnant .
  • Breastfeeding: If you are a breastfeeding mother, you should definitely mention that.
