Elcys (cysteine hydrochloride injection) is a sulfur-containing amino acid indicated to meet the nutritional requirements of newborn infants requiring total parenteral nutrition (TPN); and of adult and pediatric patients with severe liver disease who may have impaired enzymatic processes and require TPN. It can also be added to amino acid solutions to provide a more complete profile of amino acids for protein synthesis. Common side effects of Elcys include:

  • local reactions (warm sensation, redness, inflammation of veins, and blood clots at the infusion site),
  • generalized flushing,
  • fever, and
  • nausea

The recommended dosage and volume of Elcys is based upon the recommended daily protein (amino acids) requirement. For pediatric patients from birth to less than 12 years of age, the recommended dosage of Elcys is 22 mg/gram of amino acids. For adults and pediatric patients 12 years of age and older, the recommended dosage of Elcys is 7 mg/gram of amino acids. Elcys may interact with other drugs. Tell your doctor all medications and supplements you use. Tell your doctor if you are pregnant or plan to become pregnant before using Elcys; it is not expected to harm a fetus. Elcys passes into breast milk but is not expected to harm a nursing infant. Consult your doctor before breastfeeding.
