How to Self-Inject GLP-1 Medication: Step-by-Step Guide

Self-Injection Is Simpler Than It Sounds

The idea of giving yourself a weekly injection can feel daunting at first. But the needles used for GLP-1 medications are very fine and short — most patients report minimal or no discomfort after the first injection or two. Within a week or two, the process becomes quick and routine.

What You Will Need

• Your GLP-1 medication (vial or pre-filled pen)
• Insulin syringes (if using a multi-dose vial) or the pre-loaded injector pen
• Alcohol wipes
• A sharps disposal container
• Optional: small ice pack to numb the area beforehand

Step 1: Prepare Your Medication

From a Vial (Compounded Semaglutide)

1. Remove the vial from the refrigerator 30 minutes before injecting
2. Wash your hands thoroughly with soap and water
3. Wipe the rubber top of the vial with an alcohol wipe and let it air dry
4. Draw air into your syringe equal to your dose, insert needle into vial, push in air, then draw out your dose
5. Remove any air bubbles by gently tapping the syringe

Step 2: Choose Your Injection Site

GLP-1 medications are injected subcutaneously — into the fatty tissue just beneath the skin, not into muscle. Approved sites include:

• Abdomen: At least 2 inches from your belly button — the most popular site for consistent absorption
• Outer thigh: The upper, outer portion of the thigh
• Upper arm: The back of the upper arm

Rotate sites each week to prevent skin irritation, lumps, or scarring.

Step 3: Clean the Site

Wipe the chosen site with an alcohol wipe using a circular motion and allow the area to dry completely (10-15 seconds) — injecting into wet alcohol can sting.

Step 4: Inject

1. Pinch a fold of skin between your thumb and forefinger
2. Hold the syringe or pen at a 45-90 degree angle to the skin
3. Insert the needle firmly with a quick, dart-like motion
4. Push the plunger slowly and steadily until the dose is delivered
5. Hold the needle in place for 5-10 seconds after injection
6. Remove the needle smoothly — do not rub the injection site

Step 5: Dispose of the Needle Safely

Immediately place used needles into your sharps container. When full, seal and dispose of according to your local regulations.

Storage Instructions

• Unopened vials/pens: Store in the refrigerator (36-46F). Do not freeze.
• In-use vials: May be kept at room temperature for up to 28 days
• Keep away from direct sunlight and heat

Common Questions

What if I miss a dose?

If fewer than 5 days have passed, inject as soon as you remember. If more than 5 days have passed, skip the missed dose and resume your regular weekly schedule. Never double-dose.
