Typical dosage for Sodium Phenylbutyrate

Your provider will determine the right total daily dose for you or your child. The total daily dose is split into equal doses throughout the day (3 to 6 times per day). Each dose is taken with each meal or feeding.

The powder can be taken by mouth or through a feeding tube. The tablets, oral pellets (Pheburane), and oral suspension (Olpruva) can only be taken by mouth.

  • Adults and children weighing more than 44 lbs (all formulations): The dose is based on your body surface area (BSA), which takes into account both your height and weight. The typical dose is 9.9 grams/m2 to 13 grams/m2 of BSA per day.
  • Children weighing less than 44 lbs (powder and oral pellets only): The dose is based on your child's body weight. The typical dose is 450 mg/kg to 600 mg/kg of body weight per day.
