The struggle to lose weight is real

Switch your habits to something you love to do

Weight loss is a struggle that happens to many of us – and it’s not necessarily due to lack of commitment or effort. Through science, we can understand this challenge better because it turns out your brain may be working against you.

If you have found that, regardless of your commitment or your attempts with diet and exercise programs, you are just not losing weight, it might be time to talk with your doctor about adding Contrave to your weight management program.

Adding Contrave to a diet and exercise plan may help you achieve your weight loss goals.

What is Contrave?

White Arrow

Contrave is a prescription weight-loss medicine designed to help people with obesity or who are overweight achieve a healthier weight. Contrave is intended to be taken in combination with a reduced calorie diet and increased physical activity.

How Contrave works

Exactly how Contrave works to reduce weight isn’t entirely understood. However, when the two ingredients in Contrave, naltrexone and bupropion, are used together, they are thought to work on two different areas of the brain.

The hunger centre

Controls how hungry you feel and tells your brain it needs nutrition and food to satisfy this metabolic need

The reward system

Influences cravings and tells your brain it wants a specific food, even when you are not hungry

Cravings can make it difficult to adhere to a diet

Contrave reduces how hungry you feel and helps to control cravings

Studies have shown

White Arrow

People taking Contrave – along with a reduced calorie diet and increased physical activity – lose more weight than those who just follow a diet and exercise plan alone.

Who can use Contrave?

Contrave is registered for adults (18 years or older) who have a high Body Mass Index (BMI)


A BMI of
 27 kg/m2 with at least one weight-related medical problem

such as high blood pressure, high cholesterol, or type 2 diabetes

A BMI of
30 kg/m2

Contrave should be used with a reduced-calorie diet and increased physical activity.
If you have not been successful in managing your weight with diet and exercise alone,
it may time to speak with your doctor about adding Contrave to your weight management plan.

How much does Contrave cost?

White Arrow

Contrave is not funded on the Pharmaceutical Schedule and there will be a cost. The recommended retail price for Contrave is $240 per month, which equates to $8.57 per day i.e. costs less than a latte and pastry or two coffees a day. 

Normal doctor’s fees and pharmacy charges apply. While the cost of the medication is usually the same, pharmacies add a dispensing fee on top of that. This fee varies between pharmacies.

Managing your weight concerns are important and need to be shared

We understand that the cycle of dieting and gaining weight can be frustrating. This is why it’s so important to talk with your doctor. Schedule an appointment today, start the conversation about your struggles to lose weight, and ask your doctor if adding Contrave to your weight-loss plan is right for you.

What if I regain weight?

The body is ‘hardwired’ to regain lost weight, so it’s not uncommon for weight to creep back on. If this happens, it doesn’t mean you’ve ‘failed’. Remember, your body will want to return to your previous weight. So, if you notice you’ve regained even a small amount of weight (e.g. 1.5-2 kg), consider discussing this with your doctor.
