Semaglutide is dosed weekly and titrated up gradually. Most patients start at 0.25mg per week and increase every 4 weeks until they reach the target maintenance dose. The full dose range for weight loss is 0.25mg, 0.5mg, 1mg, 1.7mg, and 2.4mg.
Here's the standard escalation schedule:
Weeks 1-4 — 0.25mg
Starting dose. Adapts your body to the medication.
Weeks 5-8 — 0.5mg
Builds tolerance. Mild appetite suppression begins.
Weeks 9-12 — 1mg
First strong therapeutic dose. Noticeable appetite drop.
Weeks 13-16 — 1.7mg
Step up toward maintenance. Stronger effect.
Weeks 17+ — 2.4mg
Maintenance dose for weight loss. Used long-term.
This is the standard schedule. Your provider may adjust pace based on how you tolerate each step and how your weight loss progresses.
Starting at a low dose isn't optional — it's how the medication is designed to work safely.
Semaglutide commonly causes nausea, especially when starting or increasing the dose. The 0.25mg starting dose isn't designed to produce weight loss. It's designed to let your body get used to the medication. By the time you reach 2.4mg, most people tolerate it without significant side effects.
Jumping ahead in the schedule almost always causes problems. Your provider will move you up at the pace your body handles best.
0.25mg (weeks 1-4): the starter dose. Don't expect weight loss here. You may notice mild appetite changes or some early side effects (nausea, fatigue, mild digestive changes). This dose is about adaptation.
0.5mg (weeks 5-8): the tolerance-building dose. Appetite suppression starts becoming more noticeable. Some weight loss begins — typically modest. Side effects often flare briefly when stepping up, then settle.
1mg (weeks 9-12): the first strong therapeutic dose. Most people clearly feel the medication working here. Significantly reduced appetite, quieter food thoughts, steady weight loss for many. Side effects from the increase usually fade within 1-2 weeks.
1.7mg (weeks 13-16): step up toward maintenance. Stronger appetite suppression. Many people maintain steady weight loss at this dose. Some people stay here long-term if they're getting the results they want without needing to go higher.
2.4mg (weeks 17+): the maintenance dose for weight loss. Clinical trials showed average weight loss around 15% of body weight at 2.4mg over 68 weeks. Many people stay here long-term.
Semaglutide is injected once a week. Subcutaneously (under the skin), usually in the abdomen, thigh, or upper arm. The medication maintains a steady level in your bloodstream all week — there's no "crash" between doses.
Practical guidance:
Pick a consistent day and time. Many people choose a weekend day because it's easier to remember. Consistency matters more than the specific day.
Rotate injection sites. Move within your chosen area (abdomen, thigh, upper arm) to prevent skin irritation.
Bring the medication to room temperature first. Take it out of the fridge 15-30 minutes before injecting. Cold injections sting more.
If you miss a dose: If it's within 5 days of your scheduled dose, inject it and resume your schedule. If it's been longer than 5 days, skip it and dose on your next scheduled day. Don't double up.
Weight loss has stalled. If you've been on a dose for 8-12 weeks without meaningful progress, your provider may step you up.
Side effects are too strong. If a higher dose isn't tolerable, your provider may keep you at a lower dose longer or move back down temporarily.
You've reached your goal weight. Some people taper to a lower maintenance dose. Others stay at the full dose to hold results.
Health changes. Pregnancy, new medications, or certain conditions may require pausing or adjusting.
Can you skip a dose level?
Not recommended. The titration exists to let your body adapt. Skipping levels usually means rougher side effects.
What if you can't tolerate 0.25mg?
Most providers will extend the time at 0.25mg rather than stop entirely. Initial side effects often fade in 2-3 weeks. If they don't, your provider may suggest alternatives.
Do you have to reach 2.4mg to see results?
No. Many people see strong results at 1mg or 1.7mg. The right dose is the lowest one that gives the results you want with tolerable side effects.
What happens when you stop semaglutide?
Appetite typically returns within 2-4 weeks. Weight regain is common without a maintenance plan. If you're stopping, work with your provider on tapering and what comes next.
Can you switch from semaglutide to tirzepatide?
Yes. Some people switch if semaglutide stops being as effective or if side effects become an issue. Your provider will guide the transition. We cover the comparison in tirzepatide vs semaglutide: how to choose.
How long can you stay on semaglutide?
Most clinical guidance treats obesity as a chronic condition. There's no fixed time limit. Many people stay on a maintenance dose for years.
The right starting dose depends on your medical history, goals, and any other medications you're taking. A licensed provider will assess all of this and prescribe accordingly.
