Insulin: check your prescribed product
Biosynthetic human insulin
The FDA records the approval of biosynthetic human insulin in 1982. This established a way to manufacture human insulin using recombinant DNA technology.
The exact medicine matters
The manufacturing history of insulin does not establish the ingredients, excipients or certification of every prescription. Ask your pharmacist or prescriber about the exact product and its current product information.
Discuss suitable alternatives with a clinician
If an ingredient source matters to your religious practice, ask your pharmacist or prescriber to help identify it and discuss appropriate treatment options. Do not stop or change prescribed insulin based on this article.
