Transcript Drug Withdrawal Times

Drug and Product Labeling
 FDA requires that livestock producers use drugs only in
accordance with the label instructions
 Uses that are contrary to label directions include:
– Ignoring labeled withdrawal times
– Using the product for a species not indicated on the
label
– Using the product at a different dosage or route of
injection than stated on the label
– Using the product to treat a condition not listed on
the label
Extra Label Drug Use
 The use of a product in a manner that is different from
what is specified on the label or using any product that is
not approved and labeled for use in goats constitutes
“extra label drug use”
 FDA allows extra-label drug use under certain
circumstances when there is a valid
veterinarian/client/patient (VCP) relationship. The
prescribing veterinarian must be familiar with the herd, the
problem being treated, and that the owner is willing to
follow instructions regarding treatment. An extended
withdrawal time may be necessary to prevent drug
residues in food products.
Drug Withdrawal Times
 The withdrawal time of a drug (the time from the
last treatment to the time when products from the
animal can safely be consumed) is based on the
recommended dosage, duration of treatment, and
any extra label concerns.
 Products that are fed have withdrawal times as
well, but the extra-label use of feed additives is
not allowed by FDA. Label instructions must be
followed for a feed additive to be used in a legal
manner.
Drug Use in Dairy Goats
 Health care is the second greatest cost of
production in raising goats.

There are few drugs approved by FDA for use in
dairy goats. This means “everything is extra label”.
 Milk producers and their veterinarians should
develop a written treatment plan for disease
prevention and control.
The Drug Label
 Read the label before treatment to ensure the appropriate
medication is used in the proper strength to avoid over or
under dosing.
• The label should include: dosing information,
precautions, indications, and withdrawal times.
• Determine if the product requires special storage
(‘refrigerate’ or ‘store away from direct sunlight’).
• Determine if the age of the animal is appropriate for
this product.
• Check any expiration dates.
Drug Labels Comply With Labeling
Requirements
 All over-the-counter and prescription drugs must
contain:
– Name of drug
– Active ingredients e.g., Penicillin
– Instructions for use
– Withholding times
– Quantity of contents
– Name of manufacturer, distributor,
veterinarian + address
Drug Labels
 Drugs used “extra label” must include:
– the
veterinarian’s name, address
– dosage and route of administration
instructions
– disease/condition to be treated
– restrictions/ withdrawal period
