The Complete Semaglutide Dosing Guide

Semaglutide, sold under the brand names Ozempic (for diabetes) and Wegovy (for weight loss), is a GLP-1 receptor agonist that has become the most-prescribed weight loss medication in history. The efficacy is well-established: patients in the STEP-1 trial lost an average of 14.9% of body weight at 68 weeks. But how you dose semaglutide matters enormously. Get the titration right and side effects are manageable. Get it wrong and you'll spend six weeks miserable, or plateau early and never reach your full result.

This is the complete dosing guide.

The standard titration schedule

Semaglutide dosing follows a predictable titration protocol: start low, increase every 4 weeks. The goal is to give your gut time to adapt at each step, minimizing nausea and GI side effects.

Dosing strategy: find your minimum effective dose

The smartest semaglutide protocol in 2026 is "find the lowest dose that produces consistent appetite reduction and weight loss." Here's the mental model:

1. Titrate up until you start losing weight consistently (roughly 0.5-1% of body weight per week)
2. Hold at that dose. Don't automatically jump to the next level.
3. If weight loss stalls for 3-4 weeks, then increase.
4. Never increase faster than every 4 weeks.

Why does this matter? Higher doses don't produce meaningfully better outcomes for most patients, they just produce more side effects and more muscle loss. Lower effective doses preserve muscle, minimize GI discomfort, and allow easier long-term maintenance.

When to increase the dose

Go up when all three of these are true:

• You've been at your current dose for at least 4 weeks
• Side effects have largely subsided
• Weight loss has stalled for 2-3 weeks at the current dose (not just one bad week)

When NOT to increase the dose

• Weight loss is still progressing at 0.5-1% per week
• Side effects from the current dose are still bothersome
• You just had a stressful week, traveled, or slept poorly (assess plateau over 3+ weeks, not days)
• You've reached a weight you're comfortable maintaining

Injection mechanics

Semaglutide is a weekly subcutaneous injection, typically in the abdomen, thigh, or back of the arm. Some tips:

• Pick a consistent day of the week. Sunday evening works for many people, side effects (if any) peak 12-36 hours after injection and fade by midweek.
• Rotate injection sites. Small injection-site irritation is common and minor. Rotating prevents repeated skin reactions.
• Use a small (29-32 gauge) insulin needle if using compounded semaglutide. Branded Wegovy and Ozempic pens have built-in needles.
• Don't shake the vial. If using compounded liquid, invert gently to mix.
• Store in the fridge for long-term storage. Pens can be at room temperature for up to 28 days once in use.

Maintenance dosing

Once you've reached your target weight, the next question: do you stay on semaglutide? The honest answer is usually yes, if you stop, about two-thirds of the weight comes back within 12 months in most patients.

Options for long-term use:

• Maintenance at your therapeutic dose. Continue what worked. This is the simplest option.
• Step down to a lower maintenance dose. Some patients can hold weight at 1.0 mg or even 0.5 mg after reaching goal. Requires monitoring.
• Taper off entirely. Possible but requires dramatic lifestyle commitment, high protein, strength training, calorie discipline. Most who try this regain at least partial weight.

Handling side effects during titration

The most common issues and how to manage them:

Nausea

The #1 side effect. Peaks within 1-3 days of a dose increase. Strategies:

• Eat smaller meals, a full plate feels overwhelming on semaglutide
• Avoid very fatty or greasy foods (triggers nausea more than other macros)
• Stay hydrated
• Ginger, peppermint tea, or OTC options like Pepto can help
• If nausea is severe, step back to the previous dose and re-titrate more slowly

Constipation

GLP-1s slow gut motility. Strategies: 25-35g fiber daily, 80+ oz of water, magnesium citrate, daily walking, and if needed, a stool softener like Colace.

Fatigue

Often from under-eating early on. Make sure you're hitting at least 1,200 (women) / 1,500 (men) calories and 0.8g protein per lb of goal bodyweight.

Food aversion

Semaglutide can change taste preferences, foods you used to love may suddenly seem unappealing. Usually resolves over time. Meanwhile, eat what you tolerate.

Plateaus: what to do when weight loss stalls

Every semaglutide user plateaus eventually. Your options:

First: verify it's a real plateau

A "plateau" of one week is normal. A plateau of 3-4 weeks is real. Track weekly averages, not individual weigh-ins.

Next: tighten the fundamentals

• Re-measure food intake. "Plateau" is often calorie creep.
• Increase protein, 1.0g per lb of goal bodyweight minimum
• Add resistance training if you haven't
• Walk 8,000+ steps per day
• Audit sleep and stress

Then: consider a dose increase

If fundamentals are locked in and plateau persists, move up to the next dose level. Give it 4 weeks to assess.

Finally: consider switching to tirzepatide

If you've reached 2.4 mg semaglutide and still want more weight loss, tirzepatide often produces additional 5-10% loss thanks to its dual-receptor mechanism. See our.

Protect your muscle

The single biggest mistake on semaglutide is losing too much muscle along with fat. This is increasingly common because GLP-1s reduce appetite so much that people drop protein intake too low.

Non-negotiables on any GLP-1:

• Hit 1.0g+ of protein per pound of goal bodyweight
• Resistance train 2-4 days per week
• Don't let intake drop below 1,200 (women) or 1,500 (men) calories per day
• Monitor body composition, not just scale weight

The bottom line

Semaglutide is an extraordinarily effective tool. The patients who get the best results are the ones who titrate deliberately, keep doses modest, prioritize muscle preservation, and treat the medication as support for the fundamentals, not a replacement for them. Follow the above framework and your odds of a smooth, durable result are very high.
