You know, weight loss is never an easy task, especially when many diet pills promise to get you to your dream body with half the work of exercising and eating healthier.

If your goal is to lose a lot of weight, whether quickly or gradually over time, you must have heard of Duromine and Phentermine.

So, let’s jump right in with a quick overview of both supplements, followed by an in-depth comparison.

Phentermine vs Duromine – What are They?

While we know that both products are appetite suppressants, let’s determine the significant differences and similarities between the two.

What is Duromine?

Duromine is a popular weight loss supplement that obese people use to lose weight quickly by suppressing their appetite. It is recommended for those with a body mass index of about 30 or more. Children starting from age 12 can use it.

Duromine helps you feel fuller throughout the day by suppressing your appetite, resulting in weight loss.

Though Duromine is effective when used on its own, you will see better results when you combine Duromine with a healthy diet (3 balanced meals per day) and become more active daily.

Duromine is an anorectic medication because it suppresses the appetite and helps curb hunger and excessive overeating.

What is Phentermine?

Phentermine is a popular weight loss drug that has helped countless people to achieve their fitness goals.

Designed to suppress appetite and help users feel more energetic, Phentermine works by targeting specific receptors in the brain to increase levels of certain neurotransmitters. This increases feelings of fullness and decreases feelings of hunger.

Phentermine is available in a range of different formulations, including capsules, tablets, and extended-release tablets.

While many people use Phentermine safely, it is important that users consult with their doctor before starting any new medication, as the drug can have serious side effects for those who are not properly screened.

Despite these risks, for many people, Phentermine offers an effective way to reach their weight loss goals quickly and safely. Whether you are looking to improve overall health or build muscle and stamina, Phentermine may be the perfect choice for you.

What’s their relationship?

Phentermine is the active ingredient in Duromine, the chemical agent that causes appetite suppression leading to weight loss. While other Phentermine supplements are on the market, Duromine would not be effective without Phentermine.

Phentermine is also given as a prescription medication to those who are obese, as a different brand than Duromine. Depending on the dosage and how it works for your body, it’s almost sure to be just as effective as the Duromine prescription.

Phentermine vs Duromine Comparison

Because both products have the same active ingredient, it could lead many to believe that there is no difference between the two.

This couldn’t be further from the truth.

Both are great ways to suppress the appetite, but they operate in two different ways. Let’s look at how both supplements work for weight loss, dosage, and interacting with other medications.

Phentermine vs Duromine for Weight Loss

Both Duromine and Phentermine are excellent at suppressing the appetite, preventing overeating, and helping with weight loss and management. They don’t give the same results, though, as Duromine has a specific formula that works slightly different from your average Phentermine capsule.

The major difference in how Duromine and Phentermine work is the composition of the medications, which determine the release rate of the Phentermine in both.

The release rate is extended in the Duromine capsules, which means the capsule is slowly released into your body when you take it.

If you take Phentermine by itself, the release rate is within 3 to 4 hours, making it more of a fast-release supplement.

Both Phentermine and Duromine have a thermogenic effect on the body, producing more energy from your fat cells. This helps promote the breakdown of fat cells, leading to even more significant weight loss.


If you take the exact dosage of Phentermine and Duromine, your weight loss results should be the same. Even though the products release differently, they do the same act of suppressing your appetite.

Where you will see a difference between the two is over time, where Duromine stays in the system longer, as opposed to Phentermine by itself, which is rapidly replaced and goes into action simultaneously.

Side Effects of Duromine vs Phentermine

Duromine and Phentermine share a list of side effects common to both supplements.

These include:

  • dizziness
  • nausea
  • possible dry mouth
  • insomnia or sleeplessness
  • increased heart rate
  • other digestive issues such as constipation or diarrhea
  • unpleasant taste
  • hives
  • impotence
  • palpitations
  • hyperactivity
  • restlessness
  • tremor
  • dizziness
  • headaches

The difference between taking Phentermine by itself and taking Duromine is that Duromine gives you a lower risk of experiencing some of the severe side effects listed above.

This is because the drug would be slow-release, meaning the dosage that enters the body at any particular time would be less than taking Phentermine straight.

Due to these negative effects associated with both weight loss and appetite suppressants – we do recommend going for a much safer, healthier, and natural alternative like PhenQ appetite suppressant.

More on PhenQ later on.

Dosage & Interactions of Duromine vs Phentermine

Duromine is usually prescribed similarly to Phentermine, beginning with a smaller dosage first, then gradually increasing if necessary.

The smallest dose of Duromine is 15 mg, but the average amount prescribed to patients is 30 mg per day.

Phentermine by itself can be prescribed as low as 8 mg per day, depending on the age and lifestyle of the patient, but its average daily prescription dosage is 30 mg like Duromine.

Like Phentermine, Duromine should not be taken with certain antidepressant medications such as MAO Inhibitors like Prozac, among others. It can prove to be fatal if taken along with this medication.

Duromine should also not be taken with alcohol, ever.

Lastly, Duromine can significantly increase the heart rate, so it’s not recommended to be taken alongside caffeine or any other energy-inducing caffeine-like product.

FAQs about Phentermine vs Duromine

How much Weight Can I Lose on Duromine?

According to this study, on average, persons using Phentermine to lose weight can see a reduction of about 3 – 10% body fat in just three months.

If you’re willing to add a healthy diet and some exercise routine to that combination, you should have even better results.

Is it Hard to get Duromine?

Once you have a prescription, you can get Duromine easily, but you may be out of luck without a prescription. It is easier to get Phentermine over-the-counter blends without a prescription than to get Duromine if you are not obese.

Is Duromine Safer than Phentermine?

There is no research to conclude that Duromine is safer than Phentermine, and research has shown that they accomplish the same results.

This means that they are actually at the same level of safety, with Duromine staying in your system longer than Phentermine.

Phentermine or Duromine? Which is Best for You?

We wouldn’t categorize any of the two as better than the other, as they accomplish the same results essentially within the same time frame. However, it is essential to note that Duromine does have other inactive ingredients, as opposed to Phentermine, which only has one ingredient.

Those ingredients help with the slow release of the capsule when ingested.

Both Duromine and Phentermine require a prescription, making neither of them better in terms of accessibility. When it comes on to side effects, though, Duromine may be a better alternative than just Phentermine tablets by themselves.

The decision ultimately is yours, but we believe a superior product on the market supersedes both medications yet has similar ingredients and effective formula.

Why do we recommend PhenQ?

You don’t have to struggle to figure out whether to go with Phentermine or Duromine when there is a superior product – PhenQ. With its power-packed 5 step approach to curbing your appetite and burning fat, you’ll be shedding the pounds.

Without the side effects that come with Duromine and Phentermine.

PhenQ improves the metabolism to help your body burn fat faster and has fat blockers to prevent your body from storing excess fat from the foods you are eating.

It helps boost your mood and improve your energy levels without any excess caffeine and has worked for thousands of obese people fed up with the weight loss process.

PhenQ is also more accessible than both Duromine and Phentermine, as it doesn’t require a prescription. You can purchase it over-the-counter or online here.

Lastly, PhenQ has an all-natural and organic formula, making it great for those concerned about the sustainability factor.

In one bottle of PhenQ, you will receive sixty pills, which is enough for one month’s worth of use. A typical weight loss product gives you only thirty pills per bottle and sells it as one month’s supply.

Due to the fact that you must usually take two tablets a day, one of their bottles will only last you two weeks.

When you purchase PhenQ, you get a full thirty-day, one-month supply of weight loss pills, compared to most products. For the most effective results, we recommend our two-bottle deal, which includes one for free.

The package provides you with a full three-month supply of PhenQ for the price of only two months, which is why most of our customers opt for it.

Final Thoughts

Phentermine and Duromine are both prescription weight loss medications.

  • Phentermine is a stimulant, while Duromine is not
  • Duromine may be more likely to cause side effects than Phentermine
  • Both medications appear to be equally effective for weight loss
  • Phentermine has been around longer, so there is more data on its safety and effectiveness

The bottom line is both are effective appetite suppressants – but could lead to serious effects if care isn’t taken. This was why we highly recommended PhenQ. An all-natural fat-loss supplement for both men and women.

In addition, PhenQ contains ingredients that help to boost metabolism and burn fat. The amazing thing is that it is available without a prescription and can be purchased online when you click the banner above.
