Neumega
Neumega, also known by its generic name Oprelvekin, is a medication used in oncology to address a specific side effect of chemotherapy. It plays a crucial role in managing blood cell counts in patients undergoing cancer treatment.

Key Takeaways
- Neumega (Oprelvekin) is a recombinant human interleukin-11 (rhIL-11) that stimulates platelet production.
- It is primarily used to prevent severe thrombocytopenia (low platelet count) in adult patients receiving myelosuppressive chemotherapy for nonmyeloid cancers.
- The medication works by stimulating the growth and maturation of megakaryocytes, the cells responsible for producing platelets.
- Common side effects include fluid retention, cardiovascular issues, and eye-related problems.
- Administered via subcutaneous injection, its use helps reduce the need for platelet transfusions.
What is Neumega (Oprelvekin)?
Neumega is the brand name for Oprelvekin, a recombinant human interleukin-11 (rhIL-11). This medication is a type of cytokine, a protein that acts as a messenger between cells and plays a vital role in the immune system and blood cell production. Specifically, Oprelvekin is designed to stimulate the bone marrow to produce platelets, which are essential for blood clotting and preventing excessive bleeding. Its development marked a significant advancement in supportive care for cancer patients, offering a targeted approach to manage chemotherapy-induced thrombocytopenia.
The mechanism of action for Neumega involves binding to specific receptors on hematopoietic stem cells and megakaryocyte progenitor cells. This binding stimulates the proliferation and maturation of megakaryocytes, which are large bone marrow cells that fragment to form platelets. By accelerating this process, Neumega helps to increase platelet counts in the blood, thereby mitigating the risk of bleeding complications. This explains how Neumega work at a cellular level, directly impacting the body’s ability to produce these crucial blood components and helping maintain patient safety during intensive cancer treatments.
What is Neumega Used For?
Neumega is primarily indicated for the prevention of severe thrombocytopenia (a dangerously low platelet count) and to reduce the need for platelet transfusions in adult patients with nonmyeloid cancers who are receiving myelosuppressive chemotherapy. Chemotherapy agents often damage bone marrow, leading to a decrease in the production of all blood cells, including platelets. When platelet counts drop too low, patients are at a significantly increased risk of bleeding, which can be life-threatening.
By administering Neumega, healthcare providers aim to maintain platelet counts at a safer level, allowing patients to continue their chemotherapy treatments with fewer interruptions and reduced risk of hemorrhagic events. This targeted use addresses a critical complication of cancer therapy, improving patient safety and treatment adherence. The specific application of Neumega makes it a valuable supportive care agent in oncology.
Neumega Side Effects and Important Information
Like all medications, Neumega can cause side effects. Understanding Neumega side effects is crucial for both patients and healthcare providers. The most common adverse reactions are often related to fluid retention, which can manifest as peripheral edema (swelling in the limbs), shortness of breath, or even more serious cardiovascular effects like atrial arrhythmias or tachycardia. Patients may also experience ocular effects, such as blurred vision or conjunctival injection (redness of the eyes), and allergic reactions, though severe reactions are rare. It is important to report any unusual symptoms to a doctor promptly.
Important Neumega medication information includes careful monitoring of fluid balance, electrolyte levels, and cardiovascular status throughout treatment. Patients with a history of heart failure or other cardiovascular conditions require particular caution. Neumega is administered via subcutaneous injection, typically once daily, starting 6 to 24 hours after the completion of chemotherapy and continuing until the post-nadir platelet count recovers to a safe level or for a maximum of 14 days. It is not indicated for direct administration during chemotherapy or for patients with myeloid cancers. Regular blood tests are necessary to monitor platelet counts and assess the medication’s effectiveness and potential side effects, ensuring optimal patient management. Always consult a healthcare professional for personalized medical advice regarding Neumega, as this information is supportive only and does not replace professional medical treatment.
