Look at the Duromine package or find its image on the Internet. You will see that the medicine contains Phentermine. It may seem pointless to compare them, but only at first glance. If you go into detail, you will see important differences that may affect the selection of different anorexigenic drugs.

The article’s purpose is to explain the difference between Phentermine and Duromine because it is what many buyers care about. Let’s see what they have in common and whether you can find a meaningful difference.

What is the difference between Duromine and Phentermine

Specifics of Duromine diet pills you can buy in Australia:

  • They can prescribe it to people over 12 years of age.
  • It has the form of gelatin extended-release pills.
  • Available dosages: 15 mg, 30 mg or 40 mg.
  • The company iNova Pharmaceuticals supplies it.

Specifics of Phentermine-containing drugs sold in the USA:

  • Usually, they prescribe it to people over 18 years of age.
  • It has the form of extended or immediate-release tablets or capsules.
  • Available dosages: 8 mg, 15 mg, 30 mg or 37.5 mg.
  • Many companies manufacture it.

As you can see, there is a difference between Duromine and Phentermine from different manufacturers. It allows you to select the treatment method and dosing schedule that are the best for you.

Are Phentermine and Duromine the same

Is Phentermine the same as Duromine

In some cases, you can say YES, and in others — NO.

It is logical to assume that the satiety-enhancing effect of pills from different manufacturers will be the same for most people. As for clinical studies, there is no data showing differences in slimming pills from different manufacturers.

Are Phentermine and Duromine the same thing medically?

There is a very important point that you should consider. In some pills, inert substances affect the properties of the active ingredient:

  • Blood plasma penetration rate.
  • Activity level.
  • Time of stay in the body.

Based on this, you can’t say extended and immediate release pills are the same thing.

Phentermine GH 30 mg vs Duromine: what is the difference?

Phentermine GH is the brand name for a satiety enhancer that is almost the same as Duromine. The anorectic appeared in the Australian market after the TGA approved and certified it (spring 2020). Lupin is the manufacturer of the extended release slimming pills. The company has 7 research centers, 15 production sites and more than 20,000 specialists worldwide.

Given all the similarities, you can say YES to the question “Is Phentermine GH the same as Duromine?”. They have different excipients or inactive ingredients, manufacturers and appearance, and, perhaps, these are all the differences the diet pills have.

Contrave vs Duromine: what are 7 main differences?

These are two drugs for obesity, which have significant differences. Contrave specifics:

  1. It is a combined drug.
  2. It includes bupropion and naltrexone.
  3. It has the form of tablets.
  4. They recommend it for people with BMI ≥ 27.
  5. They take the second dose in the evening.
  6. It is for people over 18 years of age.
  7. You can use it for a long time.

It is difficult to answer the question “Is Contrave better than Duromine?”. No studies directly compare these two anorectics. Appetite suppression effectiveness is relative because it depends on people’s expectations. Some people may respond better to one of the drugs or vice versa.

We can’t say what to select, Duromine or Contrave. Only your doctor can do it after reviewing the medical history and ruling out any potential contraindications.

What is better: Saxenda or Duromine

The TGA approved the drugs for weight loss. Seven main characteristics of Saxenda:

  1. It contains Liraglutide.
  2. It is a liquid medicine for injections.
  3. It is available in multi-dose injection pens.
  4. They prescribe it to people with BMI ≥ 27.
  5. You can inject it at any time of the day.
  6. It is only for adults.
  7. Treatment duration depends on the weight lost.

Is Saxenda better than Duromine? Today many people ask this question, but the answer can’t be the same for everyone. Some people with excess weight may respond better to one of the drugs or vice versa.

If you compare the side effects of Saxenda vs Duromine, the first drug often causes various problems with the intestines and digestion. When using Phentermine-containing pills, people often report dry mouth and insomnia.

Can you take Duromine and Saxenda together

Avoid this unless advised otherwise by your doctor. These medicines can interact. If you treat obesity, tell your doctor about any drugs you use, especially appetite suppressants, CNS stimulants, or GLP-1 receptor agonists.

Metermine vs Duromine: are there any differences

You can buy the medicines in Australia and many other countries. They contain the same active ingredient, Phentermine, which reduces appetite so that you can eat less throughout the day. They are much alike and have only a few differences. You can read about them below.

Is Metermine the same as Duromine

Read and compare the instructions of one and the other medicine.

You will see no differences in terms of:

  • Indications;
  • Dosing regimen;
  • Side effects;
  • Contraindications;
  • Interaction;
  • Pharmacodynamic effects, etc.

So, you can answer the question “Is Metermine and Duromine the same?” in the affirmative.

Moreover, they have the same manufacturer – iNova Pharmaceuticals. The company is the market leader in weight loss drugs in Australia. This pharmaceutical company also supplies Contrave (another appetite suppressant).

Difference between Duromine and Metermine

Even though they come from the same manufacturer, the price of identical packs of Metermine and Duromine may vary.

There are no other significant differences between these drugs, and among the insignificant ones, one can distinguish differences in:

  • Brand name.
  • Package appearance.
  • Market launch time.

Is Metermine as effective as Duromine

No clinical studies were comparing the effectiveness of these drugs. Based on the above, you can say that when using any of them, you can control your appetite and lose about the same weight.

If you start with one diet pills and then switch to the others, there may be a difference in the rate of weight loss. It’s normal! The reason is that the effectiveness of any diet pills decreases over time.

Is Metermine the same as Duromine

Metermine 30 mg vs Duromine 30 mg

The medicines are available in capsules (burgundy gray) in blister-foil in a carton package. The inactive ingredients the capsules contain are the same. The only difference is the labeling on the capsules indicating the brand.

At the same time, the price for Metermine 30 mg is lower than for Duromine 30 mg. The drugs are popular in the Australian market and are known worldwide.

Metermine 40 mg vs Duromine 40 mg

The medicines are available in the form of capsules (orange gray) in blister-foil in a brand carton package. The inactive ingredients of the slimming pills are the same. The only difference is the labeling indicating the brand.

PhenQ vs Duromine: should you compare them

PhenQ is a highly advertised food supplement that contains only natural ingredients. The manufacturer promises that PhenQ pills or cocktails will help burn excess fat.

 Active substancePrinciple of actionEffectiveness

Capsicum extract, caffeine, chromium, vitamin B3, L-carnitine

No studies by the TGA, or other regulatory agenciesNo studies confirm that PhenQ causes clinically significant weight loss for most people
DurominePhentermineDouble effect:

  • Block neurons stimulating appetite;
  • Help in the activation of neurons and appetite-reducing MC4Rs.
  • For 3 months, you can lose up to 10% and more of the original weight


Phen375 vs Duromine: what is the difference between them

Phen375 is another food supplement that uses “Phen” in its name. The effectiveness of Phen375 is the same as described in the previous section.

Difference between Duromine and Phen375

Here’s how Phen375 is different:

  • It is a food supplement (6 natural ingredients).
  • It doesn’t contain controlled active substances such as Phentermine.
  • The TGA didn’t approve it for medication obesity treatment.
  • The manufacturer doesn’t mention that the product is for obesity treatment (this is against the law).
  • You can buy Phen375 without a prescription.
  • No data confirm that it causes clinically significant weight loss.

So, it is wrong to ask the question “Is Phen375 the same as Duromine?”. The development and official registration of drugs is a long and challenging path, with clinical trials for effectiveness and safety. They rate food supplements only as safe food products. They are not drugs to treat any disease.

Duromine vs Ozempic

The medications can help curb your appetite so that you eat fewer calories. The medicines have different mechanisms of action, and no studies were comparing them. So, it is difficult to say which drug is the best for you.

You can take Ozempic for a prolonged time. But it takes relatively long to see weight loss. You can see the effect of Phentermine-containing pills at once. But usually, you shouldn’t take them for more than 12 weeks.

Can you take Ozempic and Duromine together

Combined use of the drugs involves risks, as they have the potential for interaction. It is not known whether there is any benefit from taking the medicines at the same time. Tell your doctor if you are taking, have recently taken or plan to take any medications, especially if they are for obesity or diabetes.

Clenbuterol or Duromine

Clenbuterol is approved as an asthma drug in some countries. Using the medicine in sports and weight loss programs causes an argument. Sportsmen can’t use it during the Olympic Games, national and world competitions, although many bodybuilders take it during the “cutting” cycles.

In the battle of Clenbuterol vs Duromine, the second drug wins. It’s not a cure-all for obesity, but Therapeutic Goods Administration registered the drug. It is well-studied for safety and guaranteed to work as an appetite suppressant.

Reductil vs Duromine

Reductil is one of the CNS stimulants, which action is very similar to that of Phentermine.

However, this drug is no longer available in most pharmaceutical markets. Because of legitimate concerns about cardiovascular side effects, Reductil (Sibutramine) hasn’t been sold in Australia, Europe, the USA and other countries since 2010.


What is better, Phentermine or Duromine? We hope that in this article you will find the answer to this question.

If you look at the problem as a whole, you can say that the effectiveness of all Phentermine drugs is approximately the same. If you don’t have particular preferences, doctor’s recommendations or contraindications, you can select diet pills focusing on their availability and/or price.
