What is belzutifan?
Belzutifan is used in people with von Hippel-Lindau disease (VHL), a rare genetic condition that can cause tumors to develop in certain organs of the body.
Belzutifan is for use in adults with VHL who need treatment for certain tumors of the kidneys, pancreas, or brain and spinal cord. Belzutifan is used when these tumors do not require surgery right away.
Belzutifan may also be used for purposes not listed in this medication guide.
Warnings
Belzutifan can cause anemia (low red blood cells) or low oxygen levels. These conditions may need to be treated with blood transfusions, oxygen therapy, or hospitalization.
Call your doctor right away if you have pale skin, tiredness, feeling light-headed or short of breath, cold hands and feet, fast heartbeats, or chest pain.
Belzutifan may harm an unborn baby. Both men and women using belzutifan should use effective non-hormonal birth control to prevent pregnancy while using belzutifan and for at least 1 week after the last dose.
Before taking this medicine
Tell your doctor if you have ever had low red blood cells.
Both men and women using this medicine should use effective non-hormonal birth control to prevent pregnancy. Belzutifan can harm an unborn baby if the mother or father is using this medicine.

Belzutifan can make hormonal birth control less effective, including birth control pills, injections, implants, skin patches, and vaginal rings. Use barrier birth control to prevent pregnancy: condom, diaphragm, cervical cap, or contraceptive sponge.
Pregnancy may be less likely to occur while the mother or the father is using this medicine. Both men and women should still use birth control to prevent pregnancy because the medicine can harm an unborn baby.
Do not breastfeed while using this medicine, and for at least 1 week after your last dose.
