Understanding Weight Loss Pens: Ozempic, Wegovy, Mounjaro & Trulicity

At Samui Home Clinic, we help patients achieve safe and sustainable weight loss with medical support. One of the most popular options today is weight-loss pens — injectable medications that help control appetite and improve metabolism. But what’s the difference between Ozempic, Wegovy, Mounjaro, and Trulicity? Let’s make it simple.

Ozempic

• Active ingredient: Semaglutide

• Main use: Type 2 diabetes

• How it works: Controls blood sugar and helps you feel full longer

• Weight loss effect: Moderate — often used off-label for weight management

Wegovy

• Active ingredient: Semaglutide (same as Ozempic)

• Main use: Approved specifically for weight loss

• How it works: Higher dose designed to suppress appetite and reduce cravings

• Weight loss effect: Significant — up to 15% of body weight in studies

Mounjaro

• Active ingredient: Tirzepatide

• Main use: Type 2 diabetes, with strong weight-loss results

• How it works: Dual-action on two hormones (GLP-1 & GIP) that boost metabolism and reduce hunger

• Weight loss effect: Often greater than Ozempic or Wegovy

Trulicity

• Active ingredient: Dulaglutide

• Main use: Type 2 diabetes

• How it works: Improves blood sugar and may help modestly with weight

• Weight loss effect: Mild compared to newer pens
