Semaglutide Dosing Guide: Your Complete Schedule
Understanding semaglutide dosing helps you navigate the titration process confidently. Learn what to expect at each dose level on your weight loss journey.
In This Article
Semaglutide is dosed differently depending on whether it's prescribed for weight loss (Wegovy) or type 2 diabetes (Ozempic). Both versions require gradual titration, but the maximum doses differ significantly.
Semaglutide Dosing Overview
Key Differences by Indication
| Feature | Wegovy (Weight Loss) | Ozempic (Diabetes) |
|---|---|---|
| Starting Dose | 0.25 mg weekly | 0.25 mg weekly |
| Maximum Dose | 2.4 mg weekly | 2 mg weekly |
| Titration Duration | 16-20 weeks | 8+ weeks |
| Dose Steps | 5 levels | 3-4 levels |
Weight Loss Dosing Schedule (Wegovy Protocol)
For weight management, semaglutide follows a 16-20 week titration to reach the maintenance dose:
| Weeks | Weekly Dose | Purpose |
|---|---|---|
| Weeks 1-4 | 0.25 mg | Initial adaptation |
| Weeks 5-8 | 0.5 mg | Building tolerance |
| Weeks 9-12 | 1 mg | Therapeutic dose begins |
| Weeks 13-16 | 1.7 mg | Approaching maintenance |
| Week 17+ | 2.4 mg | Maintenance dose |
Note: Some healthcare providers may extend time at each dose level if needed for tolerability.
Diabetes Dosing Schedule (Ozempic Protocol)
For type 2 diabetes, the titration is shorter and reaches a lower maximum dose:
| Weeks | Weekly Dose | Purpose |
|---|---|---|
| Weeks 1-4 | 0.25 mg | Initial adaptation |
| Weeks 5-8 | 0.5 mg | First maintenance option |
| Week 9+ | 1 mg | Standard maintenance |
| If needed | 2 mg | Maximum dose (if 1 mg insufficient) |

What to Expect at Each Dose Level
0.25 mg - The Starting Dose (Weeks 1-4)
What this dose does: Allows your body to begin adapting to the medication. This is not a therapeutic dose for weight loss.
What to expect:
- Mild appetite reduction in some people
- Possible GI symptoms: nausea, mild stomach discomfort
- Minimal weight loss (0-2 kg typically)
- Your body is preparing for higher doses
0.5 mg - Building Tolerance (Weeks 5-8)
What this dose does: Continues adaptation and begins producing noticeable effects.
What to expect:
- More noticeable appetite suppression
- GI side effects may increase temporarily then improve
- Weight loss typically begins in earnest
- Starting to feel satisfied with smaller portions
1 mg - Therapeutic Dose (Weeks 9-12)
What this dose does: This is the first fully therapeutic dose for weight loss.
What to expect:
- Significant appetite suppression
- Reduced food thoughts ("food noise" quiets)
- Consistent weight loss (typically 3-5% body weight by now)
- Many patients see meaningful results at this level
Note: For diabetes management, many patients maintain at 1 mg long-term.
1.7 mg - Approaching Maximum (Weeks 13-16)
What this dose does: Increases effect for those who need more than 1 mg.
What to expect:
- Enhanced appetite control
- Some people experience temporary GI symptoms again
- Continued steady weight loss
- Usually well-tolerated if lower doses were tolerated
2.4 mg - Maintenance Dose (Week 17+)
What this dose does: Maximum approved dose for weight loss.
What to expect:
- Maximum medication effect
- Published clinical studies showed clinically meaningful weight loss at this dose
- Strongest appetite suppression
- Long-term maintenance dose for most weight loss patients
Why Titration is Essential
You cannot start semaglutide at 2.4 mg. Here's why gradual titration matters:
Minimizing Side Effects
GLP-1 medications slow gastric emptying. If you started at a high dose, you would likely experience severe:
- Nausea and vomiting
- Abdominal pain
- Diarrhea or constipation
- Acid reflux
Gradual increases let your digestive system adapt, making side effects much more manageable.
Finding Your Optimal Dose
Not everyone needs 2.4 mg. Some people achieve their goals at lower doses like 1 mg or 1.7 mg. By titrating slowly, you can identify the minimum effective dose for your body, which:
- Reduces side effects
- Lowers cost
- Provides room to increase later if needed
Compounded Semaglutide Dosing
Compounded semaglutide is prepared by licensed compounding pharmacies and may come in different concentrations. For information on compounded vs brand-name GLP-1 medications, see our comparison guide.
Typical Compounded Dosing
Compounded semaglutide typically follows similar titration principles:
- Start at 0.25 mg weekly
- Increase every 4 weeks as tolerated
- Target dose varies by provider protocol
Important: Always follow the dosing instructions from your prescribing healthcare provider. Compounded products may have different concentrations requiring different injection volumes.
Adjusting Your Dose
Signs You May Need a Higher Dose
- Appetite suppression has significantly decreased
- Weight loss has plateaued for 4+ weeks
- You're not yet at your goal weight
- Side effects at current dose are minimal
Learn more about when to increase your GLP-1 dose.
When to Stay at Current Dose
- You're still losing weight steadily
- Appetite is well-controlled
- You're approaching your goal weight
- Side effects are significant at current dose
If Side Effects Are Severe
If side effects are intolerable at a new dose level:
- Contact your healthcare provider
- You may step back down to the previous dose
- Try the increase again after a few more weeks
- Some people need longer at intermediate doses
Handling Missed Doses
If you miss your regular injection day:
- Within 5 days: Take the missed dose as soon as you remember, then return to your regular schedule
- More than 5 days: Skip the missed dose and take your next dose on the regularly scheduled day
Important rules:
- Never take two doses within 2 days of each other
- Don't double your dose to make up for a missed one
- You can adjust your injection day going forward if needed
Frequently Asked Questions
Can I lose weight on just 0.5 mg?
Some people do lose weight at 0.5 mg, but it's generally considered a titration dose rather than a maintenance dose. Most significant weight loss occurs at 1 mg and above. However, individual response varies.
Why is the weight loss dose (2.4 mg) higher than the diabetes dose (2 mg)?
Clinical trials showed that higher doses produced greater weight loss. Since the primary goal of Wegovy is weight management, it was approved at a higher maximum dose. Ozempic's primary goal is blood sugar control, which is achieved at lower doses.
What if I can't tolerate 2.4 mg?
Not everyone can or needs to reach 2.4 mg. Many people achieve good results at 1 mg or 1.7 mg. Your healthcare provider can help you find the dose that balances effectiveness with tolerability.
How long does semaglutide stay in your system?
Semaglutide has a half-life of about 7 days, which is why it's dosed weekly. It takes approximately 5 weeks for the medication to reach steady state in your body after starting or changing doses.
Can I increase my dose faster than the schedule?
It's not recommended. Faster titration significantly increases side effect severity. The schedule is designed for optimal tolerability. Patience during titration leads to better long-term outcomes.
Key Takeaways
- Semaglutide for weight loss titrates from 0.25 mg to 2.4 mg over 16-20 weeks
- The diabetes dose (Ozempic) maxes out at 2 mg
- Therapeutic effects begin around 1 mg for most people
- Gradual titration is essential for tolerability
- Not everyone needs the maximum dose to achieve results
