Injection technique

SC injection for vials (compounded) and pre-filled pens (branded).

Site selection

SC fat in abdomen (avoid 2 in around navel), upper thigh, or back of upper arm. Rotate sites weekly to reduce lipohypertrophy.

Compounded from vial

1. Wash hands. Pull syringe to prescribed dose.
2. Wipe vial top with alcohol. Insert needle, withdraw dose. Tap to remove air bubbles.
3. Wipe site with alcohol. Allow to dry.
4. Pinch skin gently. Insert at 90° for normal-to-overweight build.
5. Inject slowly. Hold 5–10 seconds.
6. Withdraw. Dispose in sharps container.

Branded pen

Follow device instructions exactly. Dial dose. Insert needle. Press button. Hold for count specified on pen (typically 6–10 seconds). Withdraw.

Tips

• Cold medication stings more — let warm to room temp ~30 min before
• Slow injection reduces sting
• Bruising and minor redness are normal
• Severe redness, warmth, or discharge — call prescriber
