Why log your injections
A GLP-1 injection tracker does three quiet but important jobs: it keeps you on your weekly day, it rotates your injection sites so you don’t develop lumps or irritation, and it gives you a record of side effects to spot patterns. Use it on screen or print a copy for your medicine drawer.
None of this is complicated, but all of it is easy to lose track of — especially in the early weeks when the routine is new and the doses are changing. A simple log removes the guesswork from “wait, did I already take it this week?” and “which side did I use last time?”
Rotating your injection sites
This is the part people most often neglect, and it matters. Injecting into the same spot week after week can cause irritation, bruising, and firm lumps (lipohypertrophy) that also make absorption less reliable. The fix is easy: rotate.
The three approved subcutaneous sites are:
- Abdomen — at least two inches away from your navel, either side.
- Front of the thighs.
- Back of the upper arms.
Move at least an inch from your last injection each week. The tracker’s site column lets you see your rotation at a glance so you never double up on the same spot.
Staying on schedule
Consistency helps these drugs work and keeps side effects steadier. Two rules worth knowing:
- Missed weekly dose: if your next scheduled dose is 4+ days away, take the missed one when you remember; if it’s sooner, skip it. Never stack two doses to “catch up” — that piles on nausea.
- Changing your shot day: for weekly injections you can usually shift your day as long as it’s been at least 48–72 hours since your last dose (check your drug’s label). A log makes it obvious when a switch is safe.
Watching for patterns
The notes column is more useful than it looks. Logging side effects next to each dose helps you and your clinician see what’s actually happening — whether nausea tracks with dose increases (it usually does, and usually eases), whether a particular site bothers you, or whether symptoms are settling over time. That record turns a vague “I’ve been feeling off” into something specific and actionable at your next appointment.
Print or save this alongside the weight tracker and check your titration schedule so your logged doses match your plan. This is an organizational tool, not medical advice — always follow the instructions from your prescriber and pharmacy.
