Treats Disease/Condition


RAVICTI is indicated for use as a nitrogen-binding agent for chronic management of adult and pediatric patients ≥2 years of age with urea cycle disorders (UCDs) who cannot be managed by dietary protein restriction and/or amino acid supplementation alone. RAVICTI must be used with dietary protein restriction and, in some cases, dietary supplements (e.g., essential amino acids, arginine, citrulline, protein-free calorie supplements).

How To Use

Ravicti is usually taken 3 times per day. Take with food. Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one. Ravicti can also be given through a nasogastric (NG) or gastric feeding tube as follows: After measuring the correct dose in the syringe, attach it to the feeding tube and push the plunger down to empty the syringe into the tube. Then flush the tube with 2 tablespoons of water and allow it to drain. Follow this with 2 more tablespoons of water to wash the contents down.
