Last updated: 10/3/2025

What is a NDC Code?

NDC (National Drug Code) codes are unique identifiers for medications and pharmaceutical products in the United States. Each NDC code identifies the specific drug, its manufacturer, package size, and type, helping ensure accurate medication tracking and billing.

Detailed Description

This NDC code represents tacrolimus, a prescription medication that suppresses the immune system. It is commonly used to prevent organ rejection in transplant patients and to treat certain autoimmune conditions. Tacrolimus works by reducing the activity of the immune system to prevent it from attacking transplanted organs or the body's own tissues in autoimmune diseases.

Additional Information

Tacrolimus requires careful dosing and monitoring due to potential serious side effects including increased infection risk, kidney problems, and drug interactions. Patients must follow prescribed dosing exactly and maintain regular medical follow-up.
