Why is this medication prescribed?

Endari is a medication primarily prescribed for the treatment of sickle cell disease (SCD) in both adults and pediatric patients aged 5 years and older. SCD is a genetic blood disorder characterized by abnormal hemoglobin, which can cause red blood cells to become rigid and sickle-shaped. These abnormal cells can block blood flow, leading to pain, organ damage, and other complications.

How should this medicine be used?

Endari, also known by its generic name L-glutamine oral powder, works by providing an additional source of the amino acid glutamine, which is essential for the production of red blood cells and plays a role in cellular metabolism. By replenishing glutamine levels, Endari may help reduce the frequency and severity of pain crises and other complications associated with SCD.

Endari is typically taken by mouth as an oral powder. The recommended dosage and administration instructions should be followed as prescribed by a healthcare provider. Typically, it is mixed with a specified amount of liquid or soft food and taken either with or without food. It is important to follow the healthcare provider’s instructions carefully and not to exceed the recommended dosage.

It’s crucial for patients to adhere to the prescribed dosage regimen and to continue taking Endari as directed by their healthcare provider, even if they start feeling better. Additionally, patients should inform their healthcare provider of any other medications or supplements they are taking to prevent potential drug interactions.

As with any medication, patients should discuss any questions or concerns they have about Endari with their healthcare provider to ensure safe and effective use.

Other uses for this medicine

Endari (L-glutamine oral powder) is primarily indicated for the treatment of sickle cell disease (SCD). However, there may be some off-label or investigational uses of L-glutamine in other conditions, as glutamine is an essential amino acid involved in various cellular processes. However, any such uses should only be considered under the guidance of a healthcare professional.
