A Complete Guide to Intramuscular Injections

At Geviti, we understand that starting intramuscular (IM) injections can seem daunting. We've created this guide to help you feel confident and safe in your treatment journey.

What is an Intramuscular Injection?

An intramuscular injection delivers medicine directly into your muscle tissue. This method works well because muscles have a rich blood supply, helping medications absorb properly into your body. It's often used for medicines like testosterone cypionate and vitamin B12.

Intramuscular vs. Subcutaneous Injections: Key Differences

• Intramuscular shots use longer needles to reach deep into muscle tissue
• The needle goes in at a 90-degree angle (straight up and down)
• You'll need to choose specific muscle groups that can handle the injection
• The medicine absorbs differently than subcutaneous shots

How to Give an Intramuscular Injection

Getting Ready

1. Find a clean, bright space
2. Wash your hands well with soap and water
3. Get your supplies:
   - Your medicine vial
   - A new, clean needle and syringe
   - Alcohol wipes
   - Sharps container
   - Cotton ball or gauze
   - Band-aid

Choosing Your Injection Site

Pick from these main spots:

• Vastus lateralis (outer thigh) - easiest for self-injection
• Ventrogluteal (hip) - needs help from someone else
• Dorsogluteal (upper outer buttock) - needs help from someone else
• Deltoid (upper arm) - good for smaller amounts only

Step-by-Step Injection

1. Clean the vial top with an alcohol wipe
2. Draw up your dose
3. Clean your chosen spot with a new alcohol wipe
4. Let it dry completely
5. Relax the muscle you're injecting
6. Put the needle in quickly at a 90-degree angle
7. Pull back on the plunger slightly to check for blood
8. If no blood appears, inject the medicine slowly
9. Pull the needle out at the same angle
10. Press with gauze and put on a band-aid

The Z-Track Method

For some medicines, your doctor might suggest the Z-track method:

1. Pull the skin to one side
2. Insert the needle
3. Inject the medicine
4. Pull out the needle
5. Release the skin This helps keep the medicine from leaking back out.

How to Store Your Medicine

Keep your treatment working well:

• Follow storage temperature rules
• Keep away from light
• Check expiration dates
• Store safely away from children
• Don't freeze unless specifically told to

Safe Needle Handling

After your injection:

• Don't recap needles
• Put used needles right into a sharps container
• Seal and dispose of full containers properly
• Never put loose needles in regular trash

Common Problems and Solutions

If You See Blood

• A small drop when you remove the needle is normal
• If you see blood when pulling back the plunger, remove and start over at a new spot
• Apply firm pressure if needed

If You Feel Pain

• Sharp pain going in? The needle might be dull - use a new one
• Burning? Let the alcohol dry fully next time
• Muscle aches? Try:
• • Warming the medicine to room temperature
  • Injecting more slowly
  • Using a heating pad after

If You're Nervous

• Sit down and breathe deeply
• Rest your injecting arm on a table
• Ice the area first to reduce feeling
• Consider asking someone to help

If You See Redness or Swelling

• A little redness is normal
• If you see spreading redness, feel heat, or see swelling, call your doctor
• Keep the area clean

Tips for Success

• Switch between injection sites
• Keep a log of where you inject
• Relax your muscles
• Go slowly
• Use the right size needle
• Warm up cold medicine to room temperature

When to Call Your Doctor

Get medical help if you notice:

• Fever
• Growing redness or warmth
• Severe pain
• Swelling that gets worse
• Signs of infection
• Allergic reactions
