Now before you jump to conclusions based on all of the hype out there from the countless Phentermine reviews online, let’s take a look at some important facts and see what the hype is really all about.
Phentermine Review – Does It Really Work?
It’s not uncommon today for people who are either overweight or just want to get that “beach ready” body to look for the absolute easiest way to lose weight fast.
Whether it is through the latest fad diet, exercise program or miracle diet pill, people are on the lookout for the best ways to shed those unwanted pounds and they want something that works fast.
When it comes to weight loss solutions that work and work fast, nothing can come close to the power of Phentermine.
In this review, we’ll take a closer look at one of the most popular prescription diet pills ever to hit the market and see why this diet pill is so hard to beat.
What is Phentermine?
To begin, Phentermine is a powerful prescription diet pill that is administered orally and designed to help obese patients who are at serious risk for complications lose weight quickly.
Similar to amphetamine and classified as a controlled substance, it is considered a Schedule IV Drug. 
Due to its potency, it is recommended for short term use only and only under strict supervision.
What Is Phentermine Used For?
This product is only available by prescription from your doctor and works primarily as an anorectic, suppressing your appetite for complete hunger control and thereby facilitating weight loss through a caloric deficit.
The secondary purpose for taking this weight loss pill is the effect it has on your metabolism, which will give you an increase in energy levels for a thermogenic effect in your body.
This will help to oxidize fatty acids for energy and burn off your belly fat.
The popularity of this supplement is epic.
It is one of the best diet pills on the planet and has been used by countless people over the years with great success.
Generally speaking though, all diet methods are best used with a well balanced diet, exercise, and even in some cases, behavioral or hypnotic therapy, and this product is no different.
How Does It Work?
Phentermine works by stimulating the Hypothalamus Gland, which controls part of your nervous system, as well as controlling your appetite, sleep cycles, and core temperature.
The direct effect starts in the inside of the brain with the stimulation of the adrenal glands, which in turn leads to the release of norepinephrine (responsible for the “fight or slight” response) and ultimately reducing hunger.
The secondary effect happens outside of the brain with the release of adrenaline, which leads to the breakdown of fatty acids stored in the body (belly fat) and ultimately burning them as fuel.
The main effect is hunger reduction though, which is why it is so popular.
Common Names Of Phentermine
Phentermine is (and has been) sold under many different trade names internationally and you can find the different preparations depending on your location.
While the most common preparation in the US is currently Adipex-P, you can find it sold outside the United States most commonly in a generic form.
Phentermine also has been sold in different combinations with other drugs for a synergistic effect.
Currently, the most popular preparation that is currently being sold is Qsymia, which hit the market in 2012 after gaining approval for sale in the US by the FDA.
Qsymia is a unique combination of Phentermine and Topiramate, which both have profound effects on appetite suppression and are said to be a more effective approach than taking each drug alone.
Here is a list of all of the different trade names that you can find which are either on the market or have previously been on the market:
- Adipex P (immediate release)
- Adiphene (India)
- Ionamin (discontinued in the US)
- Phentermine 37.5
- Phentermine HCL (hydrochloride)
- Pro-Fast SA
- Qsymia (with Topiramate)
- Razin (Israel)
- Phentermine Trenker
- Sinpet (MX)
- Supremin (PH)
- Suprenza (orally disintegrating tablet)
- Umine (NZ)
- Weltmine (KP)
How Do You Take It and For How Long?
Phentermine is sold in either tablets or extended release capsules, which are both administered orally.
This prescription is considered to be so powerful that it is generally prescribed only for short periods of time, commonly ranging from 3 to 6 weeks and in some situations as long as three months. 
After finishing the recommended cycle, it is recommended to take some time off.
During this time, many people choose to use an over the counter replacement for Phentermine in order to keep their results made from their cycle.
Cycles are important though, which is partially due to the fact, like any drug, it has the potential to cause serious dependence.
The proper dosage of this drug depends on the individual’s specific needs and the goal is to yield the most effective results with the lowest possible dose.
According to the information we gleaned from Drugs.com, the typical dosage is as follows:
“The usual adult dose is one tablet (37.5 mg) daily, as prescribed by the physician, administered before breakfast or 1 to 2 hours after breakfast. The dosage may be adjusted to the patient’s need.
For some patients, half tablet (18.75 mg) daily may be adequate, while in some cases it may be desirable to give half tablets (18.75 mg) two times a day.” 
Phentermine Side Effects
One of the biggest reasons that it is only prescribed for short periods of time is that it can have both common and also some adverse side effects.
Long term side effects appear to be more severe and will depend on the length of time taking the medication.
Some of the common side effects include:
- Dry mouth
- Unpleasant taste
There are also some more serious side effects that have been related to the use of this drug. These include the following:
- Rapid heart rate/palpitations
- High blood pressure
- Difficulty sleeping
- Dizzy spells
- Difficulty breathing
- Chest pain
- Changes in libido
If you are taking Phentermine and are experiencing any of these symptoms, contact your doctor immediately for professional medical advice.
Safety should always be your primary concern when on a weight loss program that includes taking diet pills.
What to do After a Cycle?
As mentioned above, all forms of Phentermine should be cycles from 3 weeks up to 3 months, depending on the recommendation from your doctor.
After your cycle has been completed and you have stopped taking these diet pills, you then have the option to take another type of over the counter diet pill such as Phentramin-D or PhenQ.
Taking an over the counter supplement should aid in helping to maintain the gains that you have made on your cycle and further assist in curbing cravings and appetite while adopting and maintaining your new healthier eating habits.
The OTC supplements may not be as strong as the actual prescription but they will help better than taking nothing at all.
Common Phentermine FAQ:
Can you buy it without a prescription?
Phentermine is schedule IV drug and not legally available over the counter in the United States without a prescription; although laws may be different in other countries.
Any diet pill that is advertized as being sold without an Rx is considered to be an over the counter dietary supplement.
Can you buy Phentermine online?
As with most prescription medications, there are online pharmacies that you can purchase this drug from.
A prescription will be required from your doctor in order to purchase it legally.
Can you take it when you are pregnant?
If you are pregnant or lactating, it is best to call your doctor for support and the best advice in this situation.
In conclusion, there is no denying that this is the reigning king of oral weight loss pills.
But as with any medication, caution and discretion is needed as well as a discussion with your doctor.
Evidence appears to indicate that it is one of the most effective means to lose weight by both decreasing your appetite and increasing thermogenesis in your body.
Taking a product like this would also be beneficial by allowing positive time to work on developing better eating and exercise habits, and perhaps any underlying reasons for being overweight as well.
Again, this is best done under a doctor’s supervision as well as working with a dietary and exercise professional.
So if you are having trouble getting down to your ideal bodyweight, ask your doctor about Phentermine diet pills and start your journey to impressive weight loss today.
