Understanding the semaglutide dosing schedule helps you know what to expect at each stage, when to expect results to improve, and what to do when things do not go to plan. Here is the complete guide.
The Standard Weight Management Titration (Wegovy / Compounded Semaglutide)
| Weeks | Dose | What to Expect |
|---|---|---|
| 1–4 | 0.25mg | Starting dose — may notice mild appetite reduction, possible light nausea |
| 5–8 | 0.5mg | First meaningful appetite suppression, 1–3 lbs/week typical, nausea may peak |
| 9–12 | 1mg | Strong appetite control, GI side effects usually improving, consistent weight loss |
| 13–16 | 1.7mg | Near-peak suppression for most people, strong satiety after small meals |
| 17+ | 2.4mg | Full maintenance dose — peak average efficacy from clinical trials |
The Diabetes Dosing Schedule (Ozempic)
Ozempic for type 2 diabetes uses a different schedule: 0.25mg for weeks 1–4 (starter dose only — not therapeutic), then 0.5mg from week 5. After at least 4 weeks at 0.5mg, dose can increase to 1mg if additional glycaemic control is needed. A 2mg dose is also available for patients needing further HbA1c reduction.
Slower Titration: Completely Valid
The standard schedule moves up every 4 weeks. But if you are experiencing significant nausea, vomiting, or GI distress at a given dose, staying at that dose for 6–8 weeks before escalating is entirely appropriate. Many physicians recommend this. There is no clinical downside to slower titration — and it typically results in better long-term tolerability and adherence.
What If You Need to Reduce the Dose?
If side effects at a higher dose are unmanageable, stepping back down to the previous dose is a valid clinical decision. Some patients find their optimal maintenance dose is 1mg rather than 2.4mg — achieving adequate weight loss with much better tolerability. This should be managed in consultation with your prescribing physician.
Missed Dose Protocol
Semaglutide has a long half-life (~1 week) so missing a single dose does not cause abrupt loss of effect. The 5-day rule: if within 5 days of your scheduled injection, inject immediately. If more than 5 days have passed, skip the missed dose and continue on your regular weekly schedule. Never double-dose.
Injection Day Consistency
Choose one day of the week and stick to it — the same day each week builds habit and makes it harder to accidentally miss. Many users pick Sunday evening (injecting before bed minimises nausea during active hours). You can change your injection day if needed — just ensure at least 2 days between doses during the transition.
Frequently Asked Questions
Q: What is the semaglutide dosing schedule?
A: Semaglutide is injected once weekly. For weight management, the standard titration schedule is: 0.25mg weeks 1–4, 0.5mg weeks 5–8, 1mg weeks 9–12, 1.7mg weeks 13–16, then 2.4mg (maintenance) from week 17 onward. For type 2 diabetes (Ozempic), the schedule is: 0.25mg weeks 1–4, 0.5mg weeks 5 onward, with option to increase to 1mg or 2mg for additional efficacy.
Q: Can you stay on a lower semaglutide dose?
A: Yes. Many patients achieve their weight loss goals at 0.5mg, 1mg, or 1.7mg and do not need to escalate to 2.4mg. If you are achieving good results and tolerating the current dose well, there is no requirement to increase. The titration schedule is a guide, not a mandate. Discuss your optimal maintenance dose with your physician.
Q: What if you miss a semaglutide injection?
A: If you miss your weekly injection and it has been 5 days or fewer since your scheduled dose, inject as soon as you remember. If it has been more than 5 days since your scheduled dose, skip the missed dose and resume on your next scheduled day. Do not inject two doses in one week to make up for a missed dose. Your next scheduled injection day remains unchanged.
