CARBAGLU Dosing and Administration

CARBAGLU® (carglumic acid) should be initiated as soon as the diagnosis of NAGS deficiency is suspected, which may be as soon as at birth, and managed by a physician and medical team experienced in metabolic disorders.

Patients should understand the importance of taking CARBAGLU exactly as prescribed—the right dose at the right time—to ensure a constant amount of medicine in their bodies.

Dosage for Pediatric and Adult Use

Acute Hyperammonemia:

  1. The recommended initial pediatric and adult dosage is 100mg/kg/day to 250 mg/kg/day.
  2. Titrate based on plasma ammonia level and clinical symptoms.

Maintenance for Chronic Hyperammonemia:

  1. The recommended pediatric and adult maintenance dose is 10 mg/kg/day to 100mg/kg/day.
