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 proper injection technique 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
- !Any uncertainty about your dose or injection technique
In case of a medical emergency — including severe allergic reaction, chest pain, or difficulty breathing — call 911 or go to the nearest emergency room immediately.
