Weight Loss Medication

A number of prescription medications have been approved by the Therapeutic Goods Administration (TGA) in Australia for the management of weight in adults. When used in combination with healthy eating, physical activity and behaviour modification, these medications can provide excellent results. The goals for drug therapy in overweight and obese people are long term weight reduction and an improvement in overall health. It is important to note that individual responses vary widely, and not every drug will be effective for every person. At Medsana Medical Clinic, we can offer medications for patients who meet the eligibility criteria (BMI >30, or BMI >27 with weight-related comorbidity).

Contrave™ (Bupropion and Naltrexone): Contrave combines 2 medications that together reduce hunger and control cravings to help you lose weight and keep it off: bupropion HCI and naltrexone HCI.  It works on the hypothalamus (hunger centre) and the mesolimbic circuit (cravings) areas of the brain.

Duromine™(Phentermine): Duromine is a mild stimulant and an appetite suppressant.  This means it reduces hunger.

Orlistat (Xenical™): Orlistat inhibits lipase in the gut. This reduces the absorption of fat by approximately 30%. The decreased absorption of calories eventually leads to weight loss.

Liragulatide (Saxenda™): Once daily injection.  Liragulatide, a glucagon-like peptide 1 (GLP-1) analogue, increases the postprandial insulin level in a glucose-dependent manner, reduces glucagon secretion, delays gastric emptying, and induces weight loss through reductions in appetite and energy intake.


The Australian Obesity Management Algorithm: A simple tool to guide the management of obesity in primary care (29 August 2022).  This algorithm guides our medication management of our patients.
