Neulasta, also known by its generic name pegfilgrastim, is a medication used to prevent infections in patients undergoing cancer treatments that can lower the number of white blood cells, specifically neutrophils, which are crucial for fighting off infections. It is a form of granulocyte colony-stimulating factor (G-CSF) that stimulates the bone marrow to produce more white blood cells. Neulasta is typically administered as a subcutaneous injection and is often given the day after chemotherapy treatment to help reduce the risk of infection during the period of neutropenia, when white blood cell counts are low. It is a long-acting version of filgrastim, designed to be given less frequently, which can be beneficial for patients undergoing treatment for various cancers, including breast and lung cancer.
When using Neulasta (pegfilgrastim), it's crucial to adhere strictly to your doctor's instructions and thoroughly read the medication label. Neulasta is used to prevent infections after certain types of cancer treatment by increasing white blood cells. While Neulasta does not generally impair your ability to drive or operate machinery, it's important to be aware of potential side effects. Common side effects include bone pain and pain in the arms or legs. Rare but serious side effects can include spleen rupture, lung damage, allergic reactions, and sickle cell crises. Given these possibilities, it's essential to monitor your health closely and report any unusual symptoms to your doctor immediately. Additionally, inform your healthcare provider about all other medications you're taking to avoid adverse interactions. Following these precautions can help ensure your treatment is both safe and effective.
