  • Avoid use of L-cysteine if patient is receiving at least 3 gram/kg per day of protein.
  • Consider oral or enteral routes for supplementation if possible.
  • Avoid using L-cysteine for catheter patency.
  • Compound in central location and add L-cysteine as a separate product from amino acid solutions to help conserve supplies.
