Complete patient guide for uses, dosage, side effects, and safety information
Quick Facts
What Is Lonquex Used For?
Lonquex is a medication that contains lipegfilgrastim, which helps stimulate the production of white blood cells in the body. It is primarily used after chemotherapy to reduce the risk of infections.
Primary Uses
Lonquex is used to help prevent infections in patients undergoing chemotherapy, as chemotherapy can lower white blood cell counts.
How It Works
Lipegfilgrastim is a modified protein that mimics a natural protein in the body, stimulating the bone marrow to produce more white blood cells, which are crucial for fighting infections.
Good to know: Lonquex is not addictive.
