CPG Sec. 400.335 Fructose-Containing Drugs
Hereditary fructose intolerance is a metabolic error due to the deficiency of fructose 1-phosphate aldolase in the liver. It is thought to be inherited as an autosomal recessive trait. The condition is characterized by symptomatic hypoglycemia and vomiting. Prolonged fructose ingestion in young children results in their failure to thrive and in jaundice, liver damage, renal impairment, and sometimes cachexia. <> There have been deaths involving the administration of IV solutions containing "Invert Sugar" to patients with hereditary fructose intolerance.
There are many drug products which contain fructose. In many cases, fructose has been identified on the product label as either levulose or invert sugar. FDA has learned that the public and many professionals are not always aware of the fact that levulose is a synonym for fructose, or that "invert sugar" is a mixture of glucose and fructose. Clearly identifying *the* presence of fructose in drugs which may be used by persons with hereditary fructose intolerance would help insure that they are not unknowingly being treated with such drugs.
All oral dosage form drugs and all parenteral drugs which contain fructose should clearly identify this ingredient as "fructose" on labels and labeling. The words "Fructose/Dextrose" should immediately follow the words "Invert Sugar" whenever they appear. The word "Fructose" should immediately follow the word "Levulose" whenever it appears.
