If you’re exploring weight loss drug options in Bunbury, WA, you’re not alone. With obesity and weight-related health concerns on the rise, more Australians are turning to medical solutions to support their weight loss goals.
Two of the most talked-about options are Duromine and Ozempic. While both can aid in weight loss, they work in very different ways and come with their own sets of benefits, risks, and considerations. Understanding how these medications differ—and which one may be more suitable for your lifestyle and health needs—is a key first step in making an informed, confident decision about your care.
How Duromine and Ozempic Work
While both Duromine and Ozempic can reduce appetite and support weight loss, they do so through very different mechanisms in the body. Understanding how each medication works can help you have more informed discussions with your GP and choose the most suitable treatment for your needs.
How Duromine Works
Duromine contains phentermine, and is a stimulant with a chemical structure similar to amphetamine. It’s typically prescribed for short-term use in individuals with a BMI over 30 or over 27 with obesity-related conditions.
It works by increasing the release of certain brain chemicals (like norepinephrine) that affect the appetite control centre in the brain. The result? You feel less hungry, which may lead you to eat less throughout the day.
Because Duromine stimulates the central nervous system, it can also increase your energy levels and alertness. However, these stimulant effects may also cause side effects such as insomnia, increased heart rate, or nervousness in some people.
How Ozempic Works
Ozempic contains semaglutide, a medication that mimics a natural gut hormone called GLP-1 (glucagon-like peptide-1). It helps regulate blood sugar and insulin levels, especially in people with type 2 diabetes. But it also plays a powerful role in controlling appetite and slowing digestion. While Ozempic is not approved for weight loss in Australia, it is sometimes prescribed off-label for this purpose.
By acting on the appetite centre in the brain, Ozempic helps you feel full sooner and for longer after eating. It also slows the movement of food through your stomach, which can reduce hunger between meals. These combined effects often lead to reduced calorie intake and gradual, sustained weight loss.

Which One Is Right for You?
The choice between Duromine and Ozempic depends on various factors:
- Health Conditions: If you have type 2 diabetes, Ozempic might be beneficial. However, its use for weight loss is off-label in Australia.
- Lifestyle: Duromine requires daily commitment, while Ozempic’s weekly injection might be more convenient for some.
- Side Effect Tolerance: Consider how each medication’s side effects align with your health profile.
- Cost Considerations: Ozempic is not subsidised by the Pharmaceutical Benefits Scheme (PBS) for weight loss, making it a more expensive option.
