What is Idhifa?
Idhifa (enasidenib) is an oral medicine that targets and blocks the abnormal IDH2 protein. In patients with IDH2-mutated AML, this protein prevents immature blood cells from developing into healthy cells. By blocking the protein, Idhifa helps restore normal cell development and supports healthier blood formation.
Doctors prescribe Idhifa mainly for:
- Adults with relapsed or refractory AML (AML that has returned or not improved after other treatments).
- Patients whose AML tests positive for the IDH2 mutation.
Warnings
Follow your doctor’s instructions carefully and always read the medication guide that comes with Idhifa.
- Differentiation syndrome: Idhifa can cause a serious condition called differentiation syndrome, which may be life-threatening. Symptoms include fever, shortness of breath, cough, chest pain, swelling in arms or legs, rapid weight gain, or low blood pressure. Seek emergency help if these occur.
- Idhifa may also affect your bilirubin levels (a substance processed by the liver). Your doctor will monitor this with blood tests.
- Do not stop or change your dose unless instructed by your healthcare provider.
