The Basics: What Is Wegovy?
Wegovy is the brand name for a once‑weekly injectable formulation of semaglutide, originally approved by the FDA in 2021 for chronic weight management in adults with obesity or overweight (BMI ≥ 27 kg/m²) plus at least one weight‑related condition (e.g., hypertension, type 2 diabetes).
- Target audience: Adults 18 + with BMI ≥ 30 kg/m², or BMI ≥ 27 kg/m² with comorbidities.
- Mode of delivery: Subcutaneous injection (abdominal, thigh, or upper arm).
- Regulatory status (2025): Still FDA‑approved; EMA and Health Canada approvals continue.
Wegovy works by mimicking the hormone GLP‑1 (glucagon‑like peptide‑1), which reduces appetite, slows gastric emptying, and improves insulin sensitivity.
Pro tip: While Wegovy is a prescription medication, lifestyle changes (balanced diet, regular activity) are essential for sustainable results.
Semaglutide Content Explained
Primary Question
How much semaglutide is in Wegovy?
| Wegovy Pen Strength | Milligrams of Semaglutide per Pen | Weekly Dose (after titration) |
|---|---|---|
| 0.25 mg pen | 0.25 mg (250 µg) | Start – 0.25 mg (Week 1) |
| 0.5 mg pen | 0.5 mg (500 µg) | Week 2 → 0.5 mg |
| 1 mg pen | 1 mg (1000 µg) | Week 4 → 1 mg |
| 1.7 mg pen | 1.7 mg (1700 µg) | Week 8 → 1.7 mg |
| 2.4 mg pen | 2.4 mg (2400 µg) | Week 12 → 2.4 mg (maintenance) |
Answer: The maintenance dose-where most patients stay for the majority of treatment-is 2.4 mg of semaglutide per week, delivered via a single 2.4 mg Wegovy pen.
Note: The titration schedule gradually increases the dose to improve tolerability and reduce gastrointestinal side effects.
Wegovy Dosage Schedule (2025 Update)
The 2025 prescribing information recommends a six‑step titration to reach the therapeutic dose of 2.4 mg. Below is the current schedule based on the most recent FDA label (as of March 2025).
| Week | Weekly Dose | Pen Used | Typical Side‑Effect Management |
|---|---|---|---|
| 1 | 0.25 mg | 0.25 mg | Start with low‑fat meals; stay hydrated |
| 2‑3 | 0.5 mg | 0.5 mg | Review GI tolerance; consider anti‑nausea diet |
| 4‑5 | 1 mg | 1 mg | Split the dose if nausea persists |
| 6‑7 | 1.7 mg | 1.7 mg | Add probiotic foods; monitor blood glucose |
| 8‑11 | 2.4 mg | 2.4 mg | Maintain steady routine; assess weight loss progress |
| 12+ | 2.4 mg (maintenance) | 2.4 mg | Continue weekly administration; annual review |
Key Takeaway: Reaching the 2.4 mg maintenance dose typically takes 12‑16 weeks, allowing the body to adapt while minimizing side effects.
How It Works: The Science Behind Weight Loss
- GLP‑1 Receptor Activation – Semaglutide binds to GLP‑1 receptors in the brain's appetite center, enhancing satiety signals.
- Delayed Gastric Emptying – Slower stomach emptying prolongs fullness after meals.
- Improved Glycemic Control – Increases insulin secretion and reduces glucagon, beneficial for those with type 2 diabetes.
Research Highlights (2022‑2024):
| Study | Population | Average Weight Loss* | Duration |
|---|---|---|---|
| STEP 1 (NEJM, 2021) | Non‑diabetic, BMI ≥ 30 | 15 % of body weight | 68 weeks |
| STEP 2 (Lancet Diabetes, 2022) | Type 2 Diabetes, BMI ≥ 27 | 12 % of body weight | 68 weeks |
| STEP 5 (JAMA, 2023) | Real‑world clinic data, 2023 cohort | 14 % of body weight | 52 weeks |
*Weight loss expressed as percent of baseline body weight.
Bottom line: Semaglutide's dual action on appetite and glucose metabolism makes it one of the most effective pharmacologic tools for chronic weight loss.
