Duromine vs Contrave

Australia's two main oral weight loss medications work through completely different mechanisms and suit very different people. Duromine is a short-term stimulant kickstart; Contrave is a long-term anti-craving treatment.

How they work differently

Duromine is a sympathomimetic stimulant. It triggers the release of norepinephrine in the brain, directly suppressing appetite signals. The effect is immediate and potent — most people feel a dramatic reduction in hunger from day one. However, tolerance develops over weeks, which is why it's limited to 12 weeks.

Contrave works through the brain's reward system. Naltrexone blocks the opioid receptors that make food pleasurable, while bupropion acts on dopamine pathways that drive cravings. Rather than simply suppressing hunger, Contrave reduces the "pull" of food — particularly cravings for sweet, fatty, and processed foods. This makes it especially effective for emotional and reward-driven eating.

Who should choose Duromine?

  • You need a quick, affordable kickstart before committing to a longer-term plan
  • Budget is tight — $300 total for the full 12-week course
  • You want to test whether appetite reduction leads to meaningful weight loss for you
  • You plan to transition to a GLP-1 medication afterward for long-term maintenance

Who should choose Contrave?

  • Your weight is driven by emotional eating, binge eating, or food cravings (not just hunger)
  • You want a long-term treatment option
  • You have co-existing depression (bupropion is an antidepressant)
  • You can't tolerate GLP-1 side effects and want an oral alternative
  • You've tried stimulant-type medications before and they didn't work

Can you use both?

Not simultaneously. However, a common approach is to use Duromine for 12 weeks as a kickstart, then transition to Contrave for long-term management. This gives you the immediate appetite suppression of Duromine followed by Contrave's sustained craving reduction. Discuss this approach with your doctor.

Neither working? Consider a GLP-1

If oral medications don't produce sufficient results, injectable GLP-1 medications like Wegovy (15–17% loss) or Mounjaro (~21% loss) are significantly more effective — at a higher price point.
