Prescription Weight Loss Medicines: 5 Important Things to Know
At ZOOM Pharmacy, many of our customers have their prescription weight loss medicine Duromine (phentermine) or Xenical (orlistat) delivered direct to their door via our online medicine delivery service.
Here are some common questions many New Zealanders have asked our Lead Pharmacist Din Redzepagic and the team about these medications.
1. Why has my doctor prescribed a weight loss medicine?
Prior to prescribing weight loss medication, your doctor will ask you to make changes to your lifestyle – including your diet, physical activity, and sleep routines.
Your doctor might prescribe a weight loss medicine for you if:
- After 6 months, diet and other lifestyle changes have not made a significant positive difference to your weight, and
- Your BMI (Body Mass Index) is higher than 30 kg/m2. You can work out your BMI using the Heart Foundation calculator
If you have other significant weight-related health issues, such as diabetes or sleep apnoea, your doctor might prescribe weight loss medication if your BMI is 27 – 30 kg/m2.
2. Do weight loss pills work?
Duromine (phentermine) and Xenical (orlistat) are the only 2 prescription medicine pills (capsules) approved for use in New Zealand. Saxenda (liraglutide) is a self-injected medication which is also now available in NZ.
- Phentermine works by suppressing appetite, so you do not feel as hungry
- Orlistat works by preventing the absorption of fat from food
- Liraglutide works by suppressing appetite and making you feel full and less hungry
These prescription medicines can help people lose a modest amount of weight.
However, weight loss medicines should always be used together with a medically controlled diet, exercise, and other lifestyle changes. They will not be effective when used on their own.
Used this way, the medication will usually help people lose more weight than they would otherwise lose with lifestyle changes alone.
Even a modest weight loss (5% – 10% of your body weight) can have important health benefits.
Your doctor will monitor the effectiveness of your medication closely. If it is not helping you lose at least 5% of your body weight, then your doctor is likely to stop this treatment.
3. Are weight loss pills safe?
Like all medicines, prescription weight loss pills can have unwanted side effects. These can range from mild to (in rare cases) severe.
If you have been prescribed a weight loss medication, your doctor has weighed up the benefits you might gain against the risks of side-effects.
Your doctor will also monitor you closely for side effects. You should always let your doctor or pharmacist know if you are concerned, feeling unwell, or are suffering worrying side effects.

- Xenical – Medsafe Consumer Medicines Information
- Saxenda – Medsafe Consumer Medicines Information
And of course, as with all prescription medicines, they should only be taken as directed by your doctor or pharmacist.
4. Is the cost of prescription weight loss medication subsidised?
Weight loss medications are not subsidised by the New Zealand government. This means you will need to pay the full cost of the medication. This can range from around $68 – $500 a month.
