Semaglutide Injection Schedule: How to Track Doses, Sites, and Progress

Educational only. Not medical advice.

Quick answer

A semaglutide injection schedule tracks four things: dose amount, injection day, injection site, and side effects. The schedule is typically weekly, with dose titration steps every few weeks as directed by your clinician.

The challenge is not the weekly shot itself — it is remembering which site you used last, what dose you are on, whether side effects are improving, and what your weight trend looks like over weeks and months.

Understanding the weekly rhythm

Semaglutide is injected once weekly. Most people pick a consistent day (Sunday evening, Wednesday morning) and stick with it. The key data points for each injection:

1. Date and time of the injection.
2. Dose amount in mg (e.g., 0.25mg, 0.5mg, 1mg, 1.7mg, 2.4mg).
3. Injection site (left abdomen, right abdomen, left thigh, right thigh, upper arm).
4. Notes: any side effects, hunger level, or observations.

This rhythm repeats every 7 days. Over 12 weeks, that is 12 data points. Over a year, 52. Without a tracking system, those data points live in memory and get lost.

Injection site rotation

Rotating sites is important for two reasons:

• Prevent tissue damage: Repeated injections in the same spot can cause lipohypertrophy — hardened fatty tissue that affects absorption.
• Maintain consistency: Different sites can have slightly different absorption rates, so tracking where you injected helps you understand variations in effect.

A simple rotation pattern:

• Week 1: Left abdomen
• Week 2: Right abdomen
• Week 3: Left thigh
• Week 4: Right thigh
• Week 5: Upper arm (left or right)
• Repeat

Track which site is next so you never have to think about it.

Titration tracking

Semaglutide typically starts at a low dose and increases over several weeks. Your clinician determines the exact schedule. Common titration patterns involve:

• Starting dose for 4 weeks
• First increase for 4 weeks
• Maintenance dose ongoing

The important thing to track is which dose step you are on and when your clinician directed the increase. If side effects are uncomfortable at a new dose, that context matters when talking to your doctor.

Side effect and symptom tracking

Common side effects include nausea, fatigue, appetite changes, and digestive changes. These often improve as the body adjusts. Tracking them helps you:

• See whether side effects are improving over time.
• Identify patterns (e.g., side effects worse 24-48 hours after injection).
• Share accurate information with your clinician.
• Distinguish between medication effects and other health factors.

For each injection, note:

• Overall side effect severity (none, mild, moderate, severe).
• Specific symptoms experienced.
• Hunger level (high, normal, low, very low).
• Any changes from the previous week.

Weight and progress tracking

Weight changes on semaglutide are gradual. Weekly weigh-ins show trends better than daily fluctuations. Track:

• Weight each week (same day, same conditions).
• Cumulative change since starting.
• Weekly rate of change.

A trend chart is more useful than a single number. If the scale stalls for 2-3 weeks, that is normal and does not mean the medication is not working.

How to organize all of this

You can use a notebook, a notes app, or a spreadsheet. But these methods have limits:

• Notebooks do not remind you when the next injection is due.
• Notes apps do not rotate sites for you.
• Spreadsheets do not show weight trend charts.

Peptiva is built specifically for this. It tracks:

• Injection schedule and dose history.
• Automatic injection site rotation.
• Side effect and symptom journal.
• Weight trend with charts.
• Hunger notes.
• Private reminders.

Everything stays on your device. No account required, no cloud sync of your medical records.

Travel and schedule disruptions

If you travel or miss a dose:

• Note the missed dose in your tracker.
• Contact your clinician for guidance on timing the next dose.
• Track any changes in side effects or hunger after a disruption.

A good tracking system logs disruptions so you can discuss them with your doctor.

Bottom line

The semaglutide schedule itself is simple — one shot per week. The complexity is in tracking sites, doses, side effects, and progress over months. Start with a structured record for each injection, and use a tool that automates the reminders and rotation so you never have to hold it all in memory.
