Types of FDA drug label guidance
Practitioners treating poultry in the United States can use FDA-approved veterinary products according to the label or in an extra-label manner. FDA labeling guidance is divided into two class-
1) On Label drug use (OLDE)
2)Extra label drug use (ELDUE)
1. On Label drug use (OLDE)
According to the label guidance, recommendations are termed’ on-label drug use, ‘ saying that all of the drug label specifications (animal species and class, administration, dose, dosing frequency/interval, indication, limitations and withdrawal time) are fulfilled and the FDA-approved the withdrawal time is observed.
The FDA-approved withdrawal timer (WDT) is the amount of time that must be observed after the last dose is administered and before the meat, eggs, or offal that is intended for human
consumption can enter the food chain.
2. Extra level drugs use (ELDUE)
In contrast to on-label drug use, medications for poultry in the United States can also be prescribed by a veterinarian for “extra-label drug use.” Extra-label drug use(ELDU) occurs when the animal species/class, administration route, dose, dosing frequency/interval, or indication differs from the FDA-approved label.
In the UnitedStates, ELDU was legalized with the passage of the Animal Medicinal Drug Use Clarification Act of 1994. When veterinary products are used in an extra-label manner, a withdrawal “interval” must be estimated based on scientific evidence and must be extended beyond the FDA-approved withdrawal time (WDT) regardless of the dose, route, or indication. It should be mentioned that legal ELDU does not include the use of prohibited drugs (such as fluoroquinolones in chickens).
