Weight loss can be challenging, especially for individuals struggling with obesity, hormonal imbalances, slow metabolism, or lifestyle-related weight gain. In recent years, injectable weight loss medications have gained significant popularity for helping patients achieve sustainable weight reduction when combined with healthy eating and physical activity.
Two of the most widely discussed prescription weight loss injections are Saxenda and Wegovy. Both medications belong to the GLP-1 receptor agonist family and work by reducing appetite, increasing feelings of fullness, and supporting long-term weight management. However, they differ in their active ingredients, dosage schedules, effectiveness, and overall weight loss potential.
At Tabib.pk, patients often ask which medication is better for weight loss. This guide explains the main differences between Saxenda and Wegovy to help you understand your options.

Saxenda is an injectable prescription medication used for chronic weight management in adults and certain adolescents with obesity or weight-related health conditions.
Its active ingredient is:
| Medication | Active Ingredient |

Saxenda works by mimicking a natural hormone that regulates appetite and food intake.
What is Wegovy?

Its active ingredient is:
| Medication | Active Ingredient |
|---|---|
