01BACKGROUND

Prepare Before You Inject

Wash your hands, gather your supplies, and inspect the pen or syringe before you start.

Check the product name, dose, and expiry date, and make sure the solution looks as expected. If the Instructions for Use say the pen should come to room temperature, follow that instruction exactly.

02MECHANICS

Injection Steps

1
Clean the injection site with an alcohol swab and let the skin dry completely.
2
Place the pen or syringe exactly as your device Instructions for Use describe.
3
Inject the medication without rushing, then keep the device in place for the full hold time in the label instructions.
4
Remove the needle or pen safely and place it in a sharps container or other approved disposal container.
5
Record the dose, site, and date in Shotlee so you can track tolerance and site rotation over time.
03WHAT TO TRACK

Tips for Painless Injections

01
🌡️
Use the Label Instructions
Follow the device-specific temperature and timing guidance instead of guessing.
02
🧴
Let Alcohol Dry
Wet alcohol stings more, so wait until the site is fully dry before injecting.
03
🔄
Rotate Sites
Use different approved sites over time so one area does not become irritated.
04
🫁
Stay Relaxed
A slow exhale and steady hand usually makes the injection feel easier.
04DEEP DIVE

Common Mistakes to Avoid

Do not reuse needles or syringes, and do not inject through clothing.

Do not rush the hold time or remove the device before the label says you can.

Do not ignore persistent redness, swelling, or pain at the injection site; track it and ask your clinician if it keeps happening.
