About This Medication

# Merck Patient Assistance Program Patient Guide: How to Get WELIREG (belzutifan) at Low or No Cost WELIREG (belzutifan) is a prescription medication used to treat certain types of advanced cancers, such as renal cell carcinoma (RCC) in adults with specific genetic mutations (like von Hippel-Lindau (VHL) disease) or tumors with **HIF-2α** mutations. The **Merck Patient Assistance Program (PAP)** helps eligible patients in the US get WELIREG for free if they meet income, residency, and insurance criteria.[1][9] ## About WELIREG (belzutifan) **WELIREG** is an oral tablet taken once daily, manufactured by Merck. It works by targeting **hypoxia-inducible factor 2-alpha (HIF-2α)**, a protein that helps cancer cells grow in low-oxygen environments. It's approved for: - Adults with VHL disease who need therapy for associated RCC, pancreatic neuroendocrine tumors (pNET), or hemangioblastomas. - Advanced RCC in patients following prior treatments like PD-1/PD-L1 inhibitors and anti-angiogenic therapies.[9] Common side effects include anemia, fatigue, musculoskeletal pain, dizziness, increased blood creatinine, and nausea. Your doctor will monitor your oxygen levels and hemoglobin due to risks like hypoxia. Always take it exactly as prescribed, with or without food, and report side effects promptly.[1][9] This guide explains how the **Merck PAP** can provide WELIREG at **no cost** to qualifying patients, easing the financial burden of treatment which can exceed $20,000 per month without assistance. ## Who Qualifies for the Program?
