Semaglutide Dosing Schedule: Complete Titration Guide

Semaglutide is one of the most effective weight loss medications ever developed — and also one of the most likely to make you feel terrible if you take too much, too fast. The dosing schedule is not arbitrary. It's specifically designed to let your body acclimate to the GLP-1 effects (slowed gastric emptying, suppressed appetite, altered gut motility) before you reach the doses that produce maximum weight loss.

This guide walks through the standard 16+ week titration schedule, what to expect at each step, when to slow down, and how to know when you've found your maintenance dose. It's based on the FDA-approved labeling for Wegovy and Ozempic plus the published evidence from the STEP clinical trial program. Your prescriber may modify this schedule based on your tolerance — and that's normal and often necessary.

Key Takeaways

• Standard titration is 16 weeks to reach the 2.4 mg maintenance dose.
• Each dose level lasts 4 weeks before the next increase.
• The days right after a dose increase are the worst of it — usually settling inside 2 weeks.
• It is normal and acceptable to extend any dose level if side effects are intolerable — patient comfort comes before reaching the target dose on schedule.
• The 2.4 mg maintenance dose is the dose tested in the pivotal STEP-1 trial that produced 14.9% mean weight loss.
• Some patients respond well at lower doses (1.0 mg or 1.7 mg) and never need to escalate to the maximum.

The Standard Semaglutide Titration Schedule

Here is the FDA-approved dosing schedule for semaglutide, used by both Wegovy and Ozempic with minor variations:

For Ozempic (type 2 diabetes), the maintenance dose is typically 1.0 mg or 2.0 mg rather than 2.4 mg. For Wegovy (chronic weight management), 2.4 mg is the target.

See our Ozempic vs Wegovy guide for why these two products use slightly different maintenance doses despite being the same active ingredient.

Week-by-Week: What to Actually Expect

Weeks 1–4: 0.25 mg (initial dose)

The 0.25 mg starting dose is intentionally below the threshold for meaningful weight loss. Its purpose is to let your gastrointestinal system acclimate to GLP-1 receptor activation without producing severe side effects.

What to expect:

• Mild nausea in the 24–72 hours after your first injection
• Slight reduction in appetite (you may notice you finish your meals less aggressively)
• Small changes in stool patterns (constipation or loose stools)
• Most patients feel essentially normal by the second injection

Weight loss: Typically 1–3 pounds total over the 4 weeks. Some patients lose nothing in this phase, which is normal.

Tips:

• Inject on the same day each week (e.g. every Sunday morning)
• Eat smaller, lower-fat meals on injection day and the day after
• Stay well hydrated

Weeks 5–8: 0.5 mg (first efficacy dose)

At 0.5 mg, the appetite-suppressing effects become much more noticeable. Most patients see meaningful weight loss in this phase.

What to expect:

• Stronger appetite suppression — meals feel "complete" much earlier
• More noticeable nausea in the 24–48 hours after injection (especially the first 1–2 weeks at this dose)
• Possible constipation (this is common and worth addressing early)
• Some patients experience fatigue or brain fog

Weight loss: 1–2 pounds per week is typical. By the end of week 8, most patients have lost 5–10 pounds total since starting.

When to slow down:

• If nausea is severe enough to interfere with daily activities
• If you're vomiting more than once a week
• If you're losing weight too fast (>2.5 lb/week consistently for 3+ weeks)
• If you're not eating enough to meet protein and nutrient needs

Weeks 9–12: 1.0 mg (building toward target)

The 1.0 mg dose is the standard maintenance dose for many type 2 diabetes patients on Ozempic. For weight loss patients, it's a stepping stone to higher doses, but some patients find it sufficient and never escalate further.

What to expect:

• Continued appetite suppression
• Side effects often *improve* compared to weeks 5–8 because your body has acclimated
• Some patients experience a renewed wave of nausea immediately after the dose increase, then improvement
• Weight loss continues at 1–2 lb/week for most

Decision point: Some patients hit their goal trajectory at 1.0 mg and don't need to escalate. Have an honest conversation with your prescriber at week 12.

Weeks 13–16: 1.7 mg (sub-maintenance, Wegovy only)

This is a Wegovy-specific titration step — Ozempic does not include 1.7 mg as a standard dose. The purpose is to ease the transition to the 2.4 mg target.

What to expect:

• The dose increase often produces 3–7 days of renewed nausea
• Continued weight loss
• Most patients tolerate this dose well

When to extend this dose: If side effects are significant or you're meeting your weight loss goals at 1.7 mg, you can stay at this dose indefinitely. There is no requirement to escalate to 2.4 mg.

Week 17+: 2.4 mg (Wegovy target maintenance)

The 2.4 mg dose is what was tested in STEP-1 and produced the headline 14.9% mean weight loss over 68 weeks. It is the target maintenance dose for Wegovy in patients who tolerate it.

What to expect:

• The strongest appetite suppression
• Maximum weight loss potential
• Side effects typically less severe than during titration because your body has fully acclimated
• Some patients still get GI symptoms in the days after each weekly injection

How long to stay: Indefinitely, as long as you tolerate it and continue to benefit. STEP-4 was a 68-week withdrawal trial. Within twelve months of stopping semaglutide, patients had put back around two-thirds of what they lost. Maintenance is long-term.

When to Slow Down or Hold a Dose

Your prescriber can — and should — modify the standard schedule based on your tolerance. Reasons to extend a dose level beyond 4 weeks:

• Severe nausea that interferes with hydration, nutrition, or daily activities
• Frequent vomiting (more than twice per week)
• Significant constipation that doesn't respond to fiber and water
• Rapid weight loss (>2.5 lb/week consistently)
• Persistent fatigue or inability to meet daily caloric needs
• Hypoglycemia in diabetes patients on insulin or sulfonylureas

Reasons to step back to a lower dose:

• Persistent severe symptoms at the current dose
• New side effect (e.g. gallbladder pain, severe abdominal pain) that requires evaluation
• Pregnancy — semaglutide is contraindicated, and it has to be stopped a minimum of 2 months ahead of conception

A reputable prescriber will not push you to escalate on schedule if you're struggling. If you're working with a GLP-1 telehealth provider, the ability to easily message your prescriber and request a dose hold is one of the most important features to evaluate.

Missed Dose Protocol

• Under 5 days late: inject as soon as you realize, and carry on with your usual day thereafter.
• Over 5 days late: let that dose go. Wait for your usual day and take the next one then.
• 2 or more doses gone, meaning over 14 days since the last injection: stop and speak to your prescriber. They will likely have you re-titrate from a lower dose to avoid the GI symptoms that come with restarting at a high dose.

Compounded Semaglutide Dosing

Compounded semaglutide from telehealth providers usually follows the same titration schedule as brand-name Wegovy. However, the exact dosing format varies — some providers ship pre-measured syringes, others ship multi-dose vials where you measure your own dose.

This is one of the most common sources of confusion (and dosing errors) in compounded semaglutide. Read our compounded semaglutide safety guide for the specifics on what to look for in a provider's dosing protocol.

Bottom Line

The semaglutide dosing schedule is a tool, not a mandate. The standard 4-weeks-per-step titration gets most patients to the 2.4 mg maintenance dose by week 17 with manageable side effects. But a sizable minority of patients need to slow down, hold at a lower dose, or even drop back temporarily — and that's not failure, it's appropriate clinical management.
