Mitapivat — Uses, Dosage, Side Effects & Safety

Drug class: Endocrine & Metabolic Disorders

Overview

Mitapivat is a prescription medication used to treat hemolytic anemia in adults with pyruvate kinase (PK) deficiency, a rare inherited blood disorder. PK deficiency leads to the destruction of red blood cells, causing symptoms like fatigue, jaundice, and shortness of breath. Mitapivat works by activating the pyruvate kinase enzyme in red blood cells, improving their energy production and survival. This helps increase hemoglobin levels and reduce the need for blood transfusions. Key points for patients: Mitapivat is taken orally as a tablet, usually twice daily. Regular blood tests are needed to monitor your response and check for side effects. Always follow your healthcare provider’s instructions and report any unusual symptoms.
