How to Self-Inject GLP-1 Medication: A Step-by-Step Guide
Self-injection is simple and nearly painless with the right technique. Follow these steps for a safe, effective injection every time.
Injection Site Reference
Use the abdomen, outer thigh, or outer upper arm. Rotate sites each week.
Step-by-Step Instructions
Gather Your Supplies
- •Your pre-filled syringe or auto-injector pen (provided in your kit)
- •Alcohol swabs (included in your kit)
- •A sharps disposal container
- •A clean, well-lit surface to work on
Tip: Remove your medication from the refrigerator 30 minutes before injecting. Room-temperature medication is more comfortable.
Choose Your Injection Site
- •Abdomen (belly): at least 2 inches away from your navel — most common site
- •Upper thigh: outer, middle portion of either thigh
- •Upper arm: outer portion of the upper arm (easier with help)
Tip: Rotate injection sites each week to prevent skin irritation or lipodystrophy (lumpy skin). Keep a simple log of where you injected last.
Clean the Area
- •Wash your hands thoroughly with soap and water for at least 20 seconds
- •Open an alcohol swab and wipe the injection site in a circular motion
- •Allow the skin to dry completely — 10–15 seconds — before injecting
Tip: Do not blow on the area or wave your hand to dry it faster. Let it air dry naturally.
Prepare the Pen or Syringe
- •Check the medication: it should be clear and colorless (or very slightly yellow). Do not use if cloudy or contains particles.
- •Remove the cap from the pen or needle. Do not touch the needle.
- •If using a pen with a dose dial, set it to your prescribed dose.
- •Prime the pen if instructed (your provider instructions will specify).
Tip: Always check the expiration date on your medication before use. Keep unused medication in the refrigerator.
Inject the Medication
- •Gently pinch about 1–2 inches of skin at your chosen site
- •Insert the needle at a 90° angle (or 45° if using a longer needle with less body fat)
- •Press the plunger or button slowly and steadily until the full dose is delivered
- •Hold for 5–10 seconds before removing to ensure full delivery
- •Release the pinch and withdraw the needle smoothly
Tip: Do not rub the injection site after — this can cause irritation. A small amount of blood or clear fluid is normal.
Dispose Safely
- •Place the used needle or syringe immediately into your sharps container — never recap
- •Never place sharps in regular trash or recycling
- •When your sharps container is ¾ full, seal and dispose per your local guidelines
- •Many pharmacies accept sharps container drop-offs for safe disposal
Tip: Check your state or city's guidelines for sharps disposal. Many areas have drop-off locations at pharmacies or health departments.
Tips for Reducing Discomfort
Most patients find GLP-1 injections cause minimal to no pain with proper technique. These tips can make the experience even more comfortable:
- 1Let medication reach room temperature before injecting (30 min out of fridge)
- 2Ensure the skin is fully dry after cleaning with the alcohol swab
- 3Inject slowly and steadily — don't rush the plunger
- 4Use a new, fresh needle for every injection — never reuse
- 5Rotate injection sites consistently
- 6Relax the muscle at the injection site — tensing up increases discomfort
- 7Try the abdomen if you find other sites more sensitive
When to Contact Your Provider
Contact your AvataCore care team if you experience any of the following:
- !Severe pain, redness, swelling, or warmth at the injection site that does not improve
- !Signs of infection: pus, fever, increasing redness or warmth
- !Severe nausea, vomiting, or abdominal pain after injecting
- !Rash, hives, difficulty breathing, or other signs of allergic reaction
- !Lumps or hard areas developing under the skin at injection sites
