Aminosyn-HF 8% (amino acid injection) is a combination of amino acids used to treatment of hepatic encephalopathy in patients with cirrhosis or hepatitis. Aminosyn-HF 8% provides nutritional support for patients with these diseases of the liver who require parenteral nutrition and are intolerant of other general purpose amino acid injections, which are contraindicated in patients with hepatic coma. Common side effects of Aminosyn-HF 8% include:

  • injection site reactions (skin redness, inflammation, warm sensation, and swelling)
  • flushing
  • fever
  • nausea
  • water weight gain
  • edema
  • increase in BUN, and
  • low blood sodium

The total dose of Aminosyn-HF 8% depends upon daily protein requirements and the patient's metabolic and clinical response. Aminosyn-HF 8% may interact with other drugs. Tell your doctor all medications and supplements you use. During pregnancy, Aminosyn-HF 8% should be used only if prescribed. Consult your doctor before breastfeeding.

Aminosyn HF 8 Professional Information



Reactions reported in clinical studies as a result of infusion of the parenteral fluid were water weight gain, edema, increase in BUN, and dilutional hyponatremia. Asterixis was reported to have worsened in one patient during infusion of the amino acid solution.

Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation and hypervolemia.

Symptoms may result from an excess or deficit of one or more of the ions present in the solution; therefore, frequent monitoring of electrolyte levels is essential.

Phosphorus deficiency may lead to impaired tissue oxygenation and acute hemolytic anemia. Relative to calcium, excessive phosphorus intake can precipitate hypocalcemia with cramps, tetany and muscular hyperexcitability.

If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures, and save the remainder of the fluid for examination if deemed necessary.
