Lesson 2

• Good Production Practice 2
• Use a veterinarian/client/patient relationship
  (VCPR) as the basis for
• medication decision-making.

2
Introduction

• This lesson will help you to
• Identify the requirements of a VCPR
• Understand the Food and Drug Administrations
  (FDA) requirement prohibiting extra-label use of
  drugs in medicated feeds
• Explain and understand over-the-counter,
  prescription, extra-label use and veterinary feed
  directive drugs

3
VCPR

• What is needed for a VCPR?
• The veterinarian must
• Have assumed the responsibility for making
  medical judgments regarding the health of the
  animal(s) and the need for medical treatment
• Have working knowledge of the animal and/or
  operation
• Be readily available for follow-up and
  consultation
• The owner/caretaker of the animal agrees to
  follow instructions of the veterinarian

4
VCPR

• Benefits of a VCPR
• Your veterinarian will be able to
• Readily follow-up
• Initiate a preliminary diagnosis much faster
• Assist you with withdrawal times and
  recordkeeping
• Provide extra-label drug use when appropriate

5
VCPR

• Involve your veterinarian
• Regular herd checks
• Timely and accurate diagnosis

6
Medication Use

• Label use
• Using an animal health product exactly as it is
  stated on the label

7
Medication Use

• Extra-Label
• When a veterinarian changes the medication dosage
  or any other instruction on the medication label

8
Medication Use

• Extra-Label
• Your veterinarian may change
• Dosage
• Frequency of administration
• Route of administration
• Duration of treatment
• Indication or condition treated
• Species or life stage treated

• No one, not even a veterinarian, can prescribe
  the extra-label use of a medicated feed

9
Medication UseExtra-label Use or Label-Use?
The label says to give 5 cc of the drug, your
veterinarian says give 10
cc. Your veterinarian suggests using a drug
approved for cattle but not for swine on your
pig. The label says treat your pig twice a
day and you treat it at 8 a.m. and 8 p.m.
