Yes, but only under medical supervision.

It depends on medical suitability and patient preference.

Administration	Weekly injection	Weekly injection
Appetite Control	Excellent	Excellent
Suitable For	Significant weight loss goals, insulin resistance, obesity management	Weight management and obesity treatment

Weight Loss Tablets vs Weight Loss Injections

Patients often ask whether tablets or injections are better for weight loss.

Weight loss injections such as Mounjaro and Wegovy are administered weekly and are designed to help regulate appetite and feelings of fullness.

Weight loss tablets may be suitable for some patients who prefer oral medication or who are not suitable for injectable treatments.

The best option depends on your medical history, treatment goals, and personal preferences.

GLP-1 Medications vs Traditional Weight Loss Medications

GLP-1 medications work by regulating appetite and increasing feelings of fullness.

Traditional weight loss medications may work through different mechanisms, such as reducing fat absorption or influencing appetite pathways.

Your clinician will discuss the benefits and considerations of each option during your consultation.
