Endari is indicated to reduce the acute complications of sickle cell disease in adult and pediatric patients 5 years of age and older. It helps decrease the frequency of painful crises and hospitalizations related to the condition.

As an amino acid, L-glutamine serves as a fuel source for cells and may help reduce oxidative stress. In sickle cell disease, glutamine supplementation is believed to improve the metabolic function of red blood cells, potentially reducing hemolysis and the adhesion of sickled cells to blood vessel walls.

Endari is a prescription medication available as an oral powder. Patients should follow dosing instructions carefully, typically taking it twice daily. Common side effects may include constipation, nausea, headache, and abdominal pain. Patients should inform their healthcare provider of all medications and supplements they are taking before starting treatment.
