The information at Drugs.com is not a substitute for medical advice. Always consult your doctor or pharmacist.

CARBAGLU treatment should be initiated by a physician experienced in metabolic disorders. Based on clinical experience, the treatment may be started as early as the first day of life.

CARBAGLU tablets are uncoated and should not be swallowed whole or crushed. Disperse CARBAGLU tablets in water immediately before use. For all preparations, use in other foods and liquids has not been studied clinically and is therefore not recommended.

Recommended Dosage

CARBAGLU 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.

Initial Dosage: The recommended initial daily dosage of CARBAGLU in pediatric and adult patients for acute hyperammonemia is 100 mg/kg to 250 mg/kg divided into 2 to 4 doses and rounded to the nearest 100 mg (i.e., half of a CARBAGLU tablet). Concomitant administration of other ammonia lowering therapies is recommended.

Maintenance Dosage: The recommended daily maintenance dosage of CARBAGLU in pediatric and adult patients is 10 mg/kg to 100 mg/kg divided into 2 to 4 doses and rounded to the nearest 100 mg (i.e., half of a CARBAGLU tablet).

Therapeutic Monitoring

Closely monitor plasma ammonia levels. Titrate the CARBAGLU dosage to maintain the plasma ammonia level within the normal range for the patient’s age, taking into consideration their clinical condition (e.g., nutritional requirements, protein intake, growth parameters, etc.).
