Overview

Semaglutide (Ozempic/Wegovy) is a GLP-1 receptor agonist FDA-approved for type 2 diabetes and chronic weight management. The slow titration protocol is critical for minimizing GI side effects. This guide covers the standard escalation schedule and practical injection tips.

What You Need

Semaglutide pen (Ozempic/Wegovy) or compounded semaglutide vial
Pen needles (for auto-injector) or insulin syringes (for compounded)
Alcohol swabs
Sharps container

Step-by-Step Instructions

Start at 0.25mg per week

The standard starting dose is 0.25mg once weekly for 4 weeks. This is a sub-therapeutic dose designed to allow GI adaptation — do not expect significant weight loss at this stage.

Tip: Inject on the same day each week (e.g., every Monday morning).

Escalate to 0.5mg at week 5

If 0.25mg is well tolerated (minimal nausea, no vomiting), increase to 0.5mg at week 5. Stay at 0.5mg for 4 weeks.

Tip: If GI side effects are significant at 0.25mg, remain at that dose for an additional 4 weeks before escalating.

Continue titration to maintenance dose

Standard Wegovy titration: 0.25mg → 0.5mg → 1mg → 1.7mg → 2.4mg, each for 4 weeks. Ozempic for diabetes: 0.25mg → 0.5mg → 1mg → 2mg. Move to the next dose only if the current dose is well tolerated.

Warning: Never skip titration steps — jumping to higher doses dramatically increases nausea and vomiting risk.

Inject subcutaneously

Inject into the abdomen, outer thigh, or upper arm. Rotate sites weekly. Use a pen needle or 29–31 gauge insulin syringe at 90°.

Tip: The abdomen is the most commonly used site — consistent absorption and easy self-injection.

Manage GI side effects

Nausea: eat smaller meals, avoid fatty/spicy foods, take the injection at bedtime. Vomiting: stay hydrated, consider anti-nausea medication. Constipation: increase fiber and water intake.

Tip: Most GI side effects peak in the first 4–8 weeks and diminish as the body adapts.

Common Mistakes to Avoid

Skipping titration steps

Fix: The titration schedule exists to minimize GI side effects. Jumping doses causes severe nausea and vomiting that leads to discontinuation.

Expecting rapid weight loss from day 1

Fix: Significant weight loss typically begins at 0.5–1mg doses after 8–12 weeks. The initial weeks are for GI adaptation.

Not adjusting diet

Fix: Semaglutide reduces appetite but does not guarantee weight loss without dietary changes. Protein-rich, lower-calorie diets maximize results.

Frequently Asked Questions

How much weight can I lose with semaglutide?

Clinical trials show average weight loss of 15–17% of body weight over 68 weeks at 2.4mg/week (Wegovy). Individual results vary significantly based on diet, activity, and adherence.

What is the difference between Ozempic and Wegovy?

Both contain semaglutide. Ozempic is FDA-approved for type 2 diabetes (max 2mg/week). Wegovy is FDA-approved for chronic weight management (max 2.4mg/week). The titration schedules differ slightly.

What happens when I stop semaglutide?

Most patients regain a significant portion of lost weight after stopping semaglutide. It is considered a chronic medication for weight management, not a short-term treatment.
