Jakafi (Ruxolitinib): Overview, Uses, and Side Effects

Jakafi (generic name: ruxolitinib) is a medication classified as a JAK inhibitor, used primarily to manage myelofibrosis—a rare type of bone marrow cancer. While Jakafi does not cure myelofibrosis, it helps control symptoms and slows disease progression. The exact cause of myelofibrosis remains unknown, but it is believed to result from mutations in bone marrow cells.

How Jakafi Works

Jakafi works by inhibiting the activity of proteins known as Janus kinases (JAKs), which are involved in regulating the immune system and blood cell production. In myelofibrosis, the dysregulated activity of JAKs contributes to the disease’s development. By blocking these proteins, Jakafi can help alleviate symptoms and decelerate disease progression.

Ongoing research continues to explore the role of JAKs in myelofibrosis, but Jakafi has proven effective in managing symptoms for many patients, making it a valuable treatment option.

Common Side Effects

While taking Jakafi, some patients may experience mild side effects, which can vary in severity:

  • Low Platelet Count (Thrombocytopenia): This condition can increase the risk of bleeding and bruising due to a decrease in platelets, the blood cells responsible for clotting.
  • Anemia: Jakafi can reduce red blood cell counts, potentially leading to symptoms such as fatigue, weakness, and shortness of breath.
  • Skin Rashes or Itching: Some patients may develop skin rashes or experience itching, which can range from mild discomfort to more severe irritation.

Serious Side Effects

Though rare, Jakafi can cause serious side effects, including:

  • Tumor Lysis Syndrome (TLS): This condition occurs when cancer cells break down rapidly, releasing their contents into the bloodstream and causing symptoms like nausea, vomiting, and confusion.
  • Liver Problems: Jakafi can sometimes lead to liver issues, indicated by increased liver enzyme levels, which may suggest liver damage.
  • Infections: By weakening the immune system, Jakafi can increase the risk of serious infections such as pneumonia or sepsis.
  • Blood Clots: Jakafi can raise the risk of developing dangerous blood clots, which can be life-threatening if they form in the lungs or heart.
  • Decreased White Blood Cell Count (Neutropenia): A reduction in white blood cells can compromise the body’s ability to fight infections.

If you experience severe symptoms, such as chest pain, shortness of breath, or a high fever, seek medical attention immediately.

Contraindications and Precautions

Certain conditions may contraindicate the use of Jakafi or require careful monitoring:

  • Pregnancy and Breastfeeding: The safety of Jakafi in pregnant or breastfeeding women has not been established. Inform your doctor if you are pregnant or planning to become pregnant.
  • Liver Problems: Patients with existing liver issues may be advised against using Jakafi, as the medication can exacerbate liver problems.
  • Low White Blood Cell Count: If you have a low white blood cell count, you may be at an increased risk of infections, and your doctor will need to monitor your condition closely.
  • History of Blood Clots: Those with a history of blood clots or who are at risk for them may be at a heightened risk while taking Jakafi.
  • Current or Recent Infections: If you have an active infection, your doctor may recommend delaying Jakafi treatment until the infection has cleared.

Always discuss your full medical history with your doctor before starting Jakafi to ensure it is safe for you.
