Ozempic Injection Site Rotation Tracker

Log each weekly injection and track your rotation across the abdomen, thighs, and upper arms. Avoid lipohypertrophy by seeing at a glance when sites were last used. Your data stays on your device only.

Why Injection Site Rotation Matters

Repeated injection into the same spot causes lipohypertrophy, a buildup of scar tissue that reduces drug absorption by 25 to 30 percent, effectively lowering your dose without you knowing it. Rotating sites systematically is one of the most underappreciated factors in GLP-1 therapy effectiveness. If you suspect a rotation problem has contributed to a stall, our guide on why Ozempic may not be working covers lipohypertrophy, dosing plateaus, and what to do next. Good injection technique also reduces site discomfort that can compound nausea during dose escalation.

1
Never inject the same spot twice in 28 days. One weekly injection means at least four distinct spots in each zone before returning to any location.
2
Rotate across all three zone types. Abdomen, thighs, and upper arms each absorb the drug at slightly different rates. Varying zones reduces predictability in absorption timing.
3
Check for hardness before injecting. Feel the area with your fingertips. A rubbery or firm patch is a sign of lipohypertrophy. Avoid that spot and let it rest for 6+ weeks.
4
Stay 2 inches from your navel. The area immediately around the belly button has dense connective tissue. Injecting here increases the chance of hitting non-subcutaneous tissue.
