Why is this medication prescribed?

Ruxolitinib is a medication that belongs to a class of drugs known as Janus kinase (JAK) inhibitors. It is primarily prescribed for the treatment of certain conditions related to bone marrow disorders, specifically myelofibrosis and polycythemia vera.

• Myelofibrosis: Ruxolitinib is used to treat myelofibrosis, a rare type of bone marrow disorder where the bone marrow is replaced by fibrous tissue, leading to problems with blood cell production. Ruxolitinib helps manage symptoms such as enlarged spleen and related complications.
• Polycythemia Vera: Ruxolitinib may also be prescribed for polycythemia vera, a condition in which the body produces too many red blood cells. This can lead to complications such as blood clots and an increased risk of cardiovascular events.

How should this medicine be used?

The use of Ruxolitinib should always be guided by a healthcare professional, and patients should follow their prescribed dosage and instructions. The information provided here is a general overview and may not cover all individual cases. It’s crucial to consult with a healthcare provider for personalized advice. Here are general guidelines on how Ruxolitinib is often used:

• Dosage: The recommended dosage of Ruxolitinib can vary based on the specific condition being treated (myelofibrosis or polycythemia vera) and the individual patient’s health status. Dosages are typically prescribed in milligrams (mg) and may be adjusted by the healthcare provider based on the patient’s response to the medication.
• Administration: Ruxolitinib is usually taken orally in the form of tablets. It is commonly taken with food to improve absorption. The tablets should be swallowed whole and not crushed or broken.
