II. Giving Injections
• Some medications may be given through the mouth (orally) or put on the skin (topically), but many are injected.
• Read the label to learn how a medication should be injected. Not following the label directions may make the medication ineffective, damage the animal’s tissue or increase withdrawal times. There are two common ways to give injections:
  - Subcutaneous or SQ: Medication is injected under the skin or hide.
- Intramuscular or IM: Medication is injected into the neck muscle.
• Can a drug ever be used differently than it says on the label?
 

- A veterinarian may prescribe a drug to be used somewhat differently than what is written on the label. This is known as extra-label drug use and is only legal when prescribed by a veterinarian.

 

III. Injection Sites
• Injections should be administered only in certain places on the animal.
  - All SQ and IM injections should be given in front of the shoulder, not on the rump or hind leg. In young pigs, SQ injections also may be given in the elbow pocket or flank.
- Giving injections in the rump or hind leg can cause damage to the most valuable meat on the animal.
• Injecting too much in one place also can damage the meat.
  - In cattle, do not give more than 10 cc per injection site.
- Larger amounts are more likely to cause abscesses and may reduce the medication’s effectiveness.

• The amount per site varies for different types and sizes of animals; for example, small pigs should only get 5 cc per site.

Are there any kinds of drugs that cannot be used extra-label?

IV. Needles

• Keep needles clean.
  - Clean needles are less likely to cause infections and abscesses.
- Cleaning needles between uses will reduce the spread of disease among animals.
• Disposable needles should be properly disposed of after use.
Use the right size:
  -The larger the needle, the more likely that it will damage the meat. Needle size is described by gauge and length. The gauge indicates diameter, or how big around, the needle is. The larger the gauge, the smaller the needle. For example, an 18-gauge needle is smaller in diameter than a 16-gauge needle.
- Use 16- or 18-gauge needles, or possibly smaller, for smaller animals.
- Use shorter needles for SQ injections than for IM
injections.
• Needles should be free of defects:
  - Defects include bent, burred or dull needles.
- If a needle is bent or broken, replace it. A bend or burr can damage muscle or part of the needle may even break off in muscle tissue.
- Change needles often. Needles become dull with use. Sharp needles will cause less tissue damage than dull ones.

V. Record Keeping

Record keeping is very important when using any kind of medication. Even though you may think you can remember everything you’ve done with your animals, sometimes you may forget when a withdrawal period is over or which medications you have given. Keeping accurate written records will help answer any questions that may arise about the medications your animals have received.
• Some of the things you need to record include:
  - which animal was sick (by ear tag, ear notches or other identification methods)
- what medication was given
- how much was given (dose)
- when (date) it was given
- withdrawal time
- who was responsible for giving the medication.
• Record this information every time a medication is used, even when the same medication is used two or three days in a row.
