Wegovy (Semaglutide) Injection Pre-Filled Pen – Comprehensive Patient Guide
Wegovy (semaglutide) is an advanced, clinically approved treatment for chronic weight management. Designed as a once-weekly injectable therapy, it supports sustainable weight loss when combined with a structured lifestyle programme, including a calorie-controlled diet and increased physical activity.
What is Wegovy?
Wegovy is a prescription-only injectable medication containing semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist. It is authorised for use in adults who are overweight or living with obesity, particularly where weight-related health risks are present.
This treatment works by targeting appetite regulation centres in the brain, helping to reduce hunger, increase satiety, and support long-term weight control. Wegovy is approved by regulatory bodies such as the U.S. Food and Drug Administration (FDA) and evaluated in accordance with standards aligned with the European Medicines Agency (EMA).
How Wegovy Works
Semaglutide mimics the natural GLP-1 hormone released in response to food intake. Its mechanisms of action include:
- Appetite suppression: Signals the brain to reduce hunger.
- Delayed gastric emptying: Slows digestion, promoting prolonged fullness.
- Improved metabolic regulation: Helps stabilise blood glucose levels.
These combined effects support sustained weight reduction and improved cardiometabolic health markers.
Wegovy Dosage Schedule
Wegovy follows a gradual dose escalation to improve tolerability:
- Month 1: 0.25 mg once weekly
- Month 2: 0.5 mg once weekly
- Month 3: 1.0 mg once weekly
- Month 4: 1.7 mg once weekly
- Maintenance: 2.4 mg once weekly
Dose adjustments should always be guided by a qualified healthcare professional.
