To begin with, let’s define that Duromine capsules contain a central nervous system stimulant called phentermine.

The drug suppresses appetite, and they prescribe it to treat obesity in combination with non-drug therapy.

So, you can give a negative answer to the question “Is Duromine a speed-based drug?”.

Speed is a slang term for a street drug. It contains methamphetamine, a substance that can make people feel happy. With regular use of speed, the feeling of “high” gradually decreases, leading people to use more and more of the drug.

Is Duromine like speed? Compare it for yourself.

What you should know about Duromine:

  • It is a legal drug approved by the TGA.
  • INova Pharmaceuticals produces the drug.
  • It suppresses hunger.
  • It causes repletion when eating a small amount of food.
  • It leads to a minimal risk of physical or mental addiction.

Essential facts about speed:

  • It is illegally produced, used, stored, and distributed.
  • It is highly addictive.
  • It reduces appetite.
  • It destroys tooth enamel fast.
  • It causes problems with the heart, kidneys, lungs, etc.

Although you can find this definition on the Internet, it is not incorrect to say that Duromine is legal speed.

Is Duromine amphetamine?

No, it is not so. These are two different drugs, and they are not bioequivalent.

However, they are referred to as the same class of compounds and have a similar chemical structure. Compare their formulas, and you will see a lot in common:

  • C9H13N – amphetamine.
  • C10H15N – phentermine.

It is worth noting that the drugs are similar in their use, but this similarity is not complete. Weight loss for obese people is one of the three indications of Amphetamine. Also, they prescribe the medicine for the treatment of:

  • Narcolepsy.
  • ADHD.

Is Duromine a stimulant?

Yes, it is a potent stimulant that causes the release of neurotransmitters into the central nervous system. The active ingredient phentermine has a strong brain activating effect, making you feel alert, energized, and not hungry.

According to clinical studies, stimulants are more effective for weight loss than other types of obesity drugs, such as Orlistat (a lipase inhibitor).

Is Duromine addictive?

Yes, it is, but only in rare cases, for example, when you misuse the drug. It has a very low risk of physical or mental addiction. So, the Therapeutic Goods Administration (Australia) has approved this drug for people with obesity.

Don’t take this medicine in higher doses or more often than recommended by your doctor, and you won’t have this adverse effect.

Does Duromine show up in a drug test?

Will Duromine fail a drug test? It is a question that many people ask these days.

They use psychoactive substance abuse testing to look for traces of banned substances in sweat, urine, saliva, or blood. Phentermine is an amphetamine-like compound officially used for the treatment of obesity. It almost always gives a false-positive result in testing for banned substances because it is chemically similar to methamphetamine.

The detection period of phentermine varies depending on the sensitivity of the testing method and factors such as:

  • Duration of Duromine use.
  • Amount of medication taken.
  • Metabolism rate.

Usually, it takes 30-40 hours for most of Duromine to leave your system. The detection period with standard tests is 1-4 days after the last dose.

But appetite suppressants and other CNS stimulants can stay in the body longer than you think. You can detect phentermine within about a month if you use hair follicles as a test sample.

Will Duromine affect drug screening, and what to do with a positive result?

As already mentioned: It will do so. But this situation should not be a problem since Duromine is a legal drug for obese people. If you have to do a test (whether at work, while driving, or in any other situation), tell them that you have health problems and use a drug for obesity. And provide a list of all prescription medications you have been using.

After a positive toxicological screening, you may need additional laboratory tests to prove that you use phentermine and nothing else.

Does Duromine show up in a roadside drug test?

In many countries, police increase the number of drug checks on the roads. It is explained by the desire to improve road safety and improve the quality of the fight against people who use drugs.

The efficiency of modern testing methods approaches 100%. If you wonder whether Duromine will show up on a roadside drug test, you may be sure that it will.

Such testing takes 3 to 5 minutes, and they do it without medical workers. The detection period for legal and illegal amphetamine-like substances is typically about 48 hours.

Can you drive on Duromine?

Yes, you can do it if you don’t have some CNS side effects.

Safe driving requires full attention. Driving can be dangerous if you have these adverse effects:

  • Dizziness.
  • Drowsiness.
  • Coordination problems.
  • Reduced reaction time, etc.

You should not drive a car, ride a bicycle, or use specific tools or machinery until you know how this medicine affects you.

Does Duromine show up on a mouth swab drug test?

Phentermine gets into the blood and other body fluids, including saliva. So, saliva samples may show the presence of the stimulant.

There are saliva tests designed to detect a specific type of substance. So, tests for alcohol or marijuana will be negative if phentermine is present in the body.

If you want to know the answer to the question “How long does Duromine stay in your saliva?” it is about two days. The time you need to detect this drug in saliva may depend on the type and sensitivity of the test.

Does Duromine show up in a blood test?

If you want to know the answer to the question “Will Duromine show up in a blood test?” it can be positive or negative.

Yes, it is possible (within 24 hours after taking the last capsule) if the analysis searches for banned substances.

Laboratory blood tests are very specific. You can not detect phentermine and other drugs of this type if it is a standard blood test, such as measuring the percentage of blood elements (platelets, red blood cells, white blood cells).

Does Duromine show up in urine tests?

Yes, it is possible.

If you take Duromine, a urine drug test for prohibited substances may give a false-positive result.

The thing is that liver enzymes metabolize only a small part of phentermine. Most of this substance (from 60% to 85%) is excreted from the body with urine.

Depending on the dose size and the type of test reagents, you can detect the drug in the urine 1-4 days after the last dose.

It is worth noting that routine urine tests, such as those designed to check for diabetes or urinary tract disorders, will not detect phentermine.

How long does Duromine stay in your system?

For the last 45 years, this drug has been thoroughly studied. Numerous clinical studies give much information about its pharmacokinetic characteristics (absorption, distribution, metabolism, and excretion).

The human bodies are different. So, the answer to the question “How long does it take for Duromine to wear off?” may vary for different people.

If you mean the Duromine half-life, this time is 25 hours for most people taking the drug. For some people, the elimination time of half the drug is reduced to 7-8 hours. It is believed that the drug is eliminated after 5 half-life periods.

The following factors influence the time of drug elimination from the body:

  • Age.
  • Mass of fat and muscle tissue.
  • Metabolism rate.
  • Genetics.
  • Liver function.
  • Metabolism disorders.

They always take Duromine in the morning before breakfast. Since these are extended-release capsules, the active substance is absorbed approximately 3 times slower than regular tablets. So, you can control your appetite and food intake for most of the day. In the late afternoon and at night, the levels of Duromine come down.


As you have already understood, Duromine is a legal drug prescribed to reduce body fat in addition to a weight management plan. It has nothing to do with speed or other illegal and banned drugs. Duromine only has a psychostimulant effect so that you can cope with the problem of overeating and is not for other purposes.
