What if I want to deviate from ELDU regulations? -ANSWERS-Deviation from ELDU
regulations is an illegal action subject to prosecution by the FDA. The spirit of AMDUCA
is to allow veterinarians flexibility in administering drugs that will help relieve animal pain
and suffering. The overarching premise of the law is that extralabel use is acceptable
when filling a medical need for an animal when its health is threatened.
Can clients themselves decide to administer drugs in an extralabel fashion to their
animals? -ANSWERS-No, clients cannot decide to administer drugs in an extralabel
fashion. However, according to AMDUCA, if a VCPR exists, and the veterinarian
decides that ELDU is a valid option, the client may administer the drug in an extralabel
fashion as long as it is under the supervision of the veterinarian.
Do I need to list a withdrawal time if the ELDU is for a non food-producing animal? -
ANSWERS-The withdrawal time of a drug prescribed for ELDU for a non-food-
producing animal is not necessary according to AMDUCA.
Are vaccines subject to ELDU? -ANSWERS-Vaccines are considered "veterinary
biologics" and fall under regulation by the USDA Center for Veterinary Biologics (USDA
CVB). Veterinarians are allowed discretionary use of vaccines. For example, if a minor
species requires a vaccine not labeled for that species, the veterinarian can employ
discretionary use of a particular vaccine as he or she sees best fit. Veterinarians should
check state rules to discern whether it is acceptable to vaccinate animals with vaccines
labeled for another animal species.
Are pesticides subject to ELDU? -ANSWERS-The use of pesticides by a veterinarian is
not subject to ELDU regulations as these are subject to the primary jurisdiction of the
Environmental Protection Agency (EPA). Pesticides must always be used according to
the instructions on the label.
,What is the difference between an "expiration date" on the VFD and duration of use? -
ANSWERS-While the VFD expiration date defines the period of time for which the
authorization to feed an animal feed containing a VFD drug is lawful, the duration of use
determines the length of time, established as part of the approval, conditional approval,
or index listing process, that the animal feed containing the VFD drug is allowed to be
fed to the animals. For example, in swine the currently approved VFD drug tilmicosin
has a duration of use of 21 days and an expiration date of 90 days, which means the
client has 90 days to obtain the VFD feed and complete the 21 day course of therapy
What is an "extralabel use" of a VFD drug and is it allowed? -ANSWERS-"Extralabel
use" is defined in FDA's regulations as actual or intended use of a drug in an animal in a
manner that is not in accordance with the approved labeling. For example, feeding the
animals VFD feed for a duration of time that is different from the duration specified on
the label, feeding VFD feed formulated with a drug level that is different from what is
specified on the label, or feeding VFD feed to an animal species different than what is
specified on the label would all be considered extralabel uses. Extralabel use of
medicated feed, including medicated feed containing a VFD drug or a combination VFD
drug, is not permitted.
What is a "combination VFD drug"? -ANSWERS-A "combination VFD drug" is an
approved combination of new animal drugs intended for use in or on animal feed under
the professional supervision of a licensed veterinarian, and at least one of the new
animal drugs in the combination is a VFD drug.
How did ELDU regulation come about and why is it necessary in veterinary medicine? -
ANSWERS-Prior to enactment of the AMDUCA, the Federal Food, Drug, and Cosmetic
Act had provided that a new animal drug was deemed unsafe unless it was subject to
the FDA's stringent approval process - for exactly what was on the label - specific
species, disease indication, dose, duration, frequency, and route of administration.
Created a relative disincentive for companies to put resources toward creating new
veterinary drugs. Making it harder to treat.
Minor species have few to no drugs approved for various indications.
,Who regulates ELDU and enforces the regulations? -ANSWERS-The FDA Center for
Veterinary Medicine regulates ELDU and enforces the regulations. In cases of
AMDUCA violations, FDA regulatory actions may include warning letters, seizure of
product, misdemeanor fines, injunction or criminal prosecution.
Is "off-label" use the same as ELDU? -ANSWERS-"Off-label" is a term commonly used
in foreign countries, and by physicians in the United States. It is also sometimes used in
veterinary medicine in the U.S., but the term has no legal or regulatory definition. In the
United States, extralabel drug use is the appropriate term.
How do I know what qualifies as ELDU? -ANSWERS-Specific criteria must be followed:
-A valid VCPR is a prerequisite for all ELDU;
-Only a veterinarian can determine that ELDU is needed and can administer, prescribe
or dispense a medication extralabelly. The veterinarian must direct or supervise ELDU
in an animal;
-ELDU rules only apply to FDA-approved animal and human drugs;
-ELDU is intended for prevention, treatment, and control purposes only when an
animal's health is threatened.
-ELDU is not permitted if it results in an illegal food residue, or any residue which may
present a risk to public health;
-A veterinarian must not pursue use of certain FDA-prohibited drugs in food-producing
animals
ELDU of an FDA approved drug may be used if: -ANSWERS--There is no approved
animal drug that is labeled for such use, or that contains the same active ingredient in
the required dosage form and concentration.
-Alternatively, an approved animal drug for that species and condition exists, but a
veterinarian finds, within the context of a VCPR, that the approved drug is clinically
ineffective for its labeled use.
The following additional conditions must be met for ELDU in food-producing animals: -
ANSWERS--Such use must be accomplished in accordance with an appropriate
medical rationale; and
, -If scientific information on the human food safety aspect of the use of the drug in food
producing animals is not available, the veterinarian must take appropriate measures to
assure that the animal and its food products will not enter the human food supply.
An approved animal drug must be considered for the particular use before a drug
labeled for humans is considered. The prescribed or dispensed extralabel drug
(prescription legend or over-the-counter) must bear labeling information which is
adequate to assure the safe and proper use of the product.
What drugs qualify for ELDU? -ANSWERS-Any drug approved by the FDA qualifies for
ELDU in a non-food-producing animal given that a valid VCPR exists and FDA-
delineated criteria are met. For food-producing animals, the extralabel use of certain
drugs is prohibited.
When is ELDU used/necessary? -ANSWERS-Extralabel use is limited to circumstances
when the health of an animal is threatened, or suffering or death may result from failure
to treat. As we've already stated, extralabel use to enhance production is prohibited.
What drugs are currently restricted from ELDU? -ANSWERS-FDA may prohibit the
extralabel use of an approved new animal or human drug or class of drugs in animals if
FDA determines that:
1- An acceptable analytical method for residue detection needs to be established and
such method has not been established or cannot be established, or
2- The extralabel use of the drug or class of drugs presents a risk to public health.
A prohibition may be a general ban on the extralabel use of the drug or class of drugs or
may be limited to a specific species, indication, dosage form, route of administration, or
combination of factors.
To date, the ELDU of the following drugs has been prohibited in food-producing
animals, regardless of whether or not the criteria for ELDU are met: -ANSWERS-1-
Chloramphenicol;
2- Clenbuterol;
3- Diethylstilbestrol (DES);
