1. Pinch a small area of skin on the thigh, upper arm, or abdomen.
2. Insert the needle at a 45degree angle.
3. Push the plunger fully until you hear the click.
4. Hold pressure for a few seconds, withdraw the needle, and let the safety guard cover it.

Athome injection (pen)

2. Press the pen flat against your skin (usually the thigh or abdomen) and press the button.

Missed Doses

What to do if you're late?
