HUMULIN SUMMARY
Humulin is synthesized in a special non-disease-producing laboratory strain of
Escherichia coli
bacteria that has been genetically altered by the addition of the gene for human insulin production. Humulin R (U-500) consists of zinc-insulin crystals dissolved in a clear fluid. Humulin R (U-500) is a sterile solution and is for subcutaneous injection. It should not be used intravenously or intramuscularly. The concentration of Humulin R (U-500) is 500 units/mL.
Humulin R (U-500) is especially useful for the treatment of diabetic patients with marked insulin resistance (daily requirements more than 200 units), since a large dose may be administered subcutaneously in a reasonable volume.
