About Wegovy® Injectable Pen

About Wegovy® (Semaglutide) Injectable Pen

Wegovy® contains semaglutide, a once-weekly injectable medicine for weight management in adults who are overweight or obese. It works by helping to regulate appetite, leading to reduced calorie intake and supporting long-term weight loss when used alongside diet and exercise.

What the medicine is

  • Pre-filled, single-use injection pens containing semaglutide.
  • Available in 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, and 2.4 mg strengths for stepwise dose escalation.

How it works

  • Semaglutide is a GLP-1 receptor agonist.
  • It mimics the natural hormone GLP-1, reducing appetite and slowing stomach emptying.
  • This helps decrease food intake and supports sustainable weight reduction.

What it is used for

  • Weight management in adults with a BMI ≥30 kg/m² (obesity) or ≥27 kg/m² with at least one weight-related condition (e.g., type 2 diabetes, hypertension, dyslipidaemia, sleep apnoea).

Benefits

  • Once-weekly dosing for convenience.
  • Clinically proven to deliver significant, sustained weight loss in combination with lifestyle changes.
  • Improves cardiovascular and metabolic health markers such as blood sugar and blood pressure.

How to Use Wegovy® Injectable Pen

Directions for Use

  • Inject Wegovy once weekly, on the same day each week, under the skin (abdomen, thigh, or upper arm).
  • Rotate injection sites with each dose.
  • Typical dosing starts at 0.25 mg weekly, increasing gradually every 4 weeks (0.5 mg → 1 mg → 1.7 mg → maintenance 2.4 mg) as tolerated.
  • Pens are single-use, pre-filled, and disposable after one injection.

Special advice

  • Can be taken with or without food.
  • If using oral contraceptives, consider additional protection for 4 weeks after starting or increasing dose.

Missed dose

  • If remembered within 5 days, inject as soon as possible, then continue as normal.
  • If more than 5 days late, skip and resume on the next scheduled day.

Storage

  • Store in a refrigerator (2–8°C) until use.
  • May be kept at room temperature (below 30°C) for up to 28 days.
  • Do not freeze. Protect from light.

When to seek review

  • If you experience persistent vomiting, severe abdominal pain, or cannot tolerate dose increases.
  • If weight loss plateaus despite full dosing and lifestyle measures.
