Typical dosage for Cystagon

Your provider will typically prescribe a lower dose of Cystagon to start, then raise it slowly over 4 to 6 weeks until you've reached the recommended maintenance dose.

  • People ages 12 years and older (weighing 110 lbs or more): The typical maintenance dose is 500 mg by mouth every 6 hours.
  • People under 12 years old (weighing 110 lbs or less): Your child's provider will calculate their dose based on body surface area (BSA), which takes into account your child's height and weight. In general, the maintenance dose ranges from 100 mg to 450 mg by mouth every 6 hours.

Your provider will adjust your dose based on how well the medication is lowering your cystine levels and if you're having side effects.
