Phentermine is a medicine which produces a loss of appetite, resulting in lower food consumption, leading to weight loss.

It is normally prescribed for obese patients with over-weight related illnesses.

Phentermine is classified as a controlled substance in many countries, because of its amphetamine-like effects.

Internationally, It is a schedule IV drug under the Convention on Psychotropic Substances.

In the United States, it is classified as a Schedule IV controlled substance under the Controlled Substances Act  (CSA).

According to the U.S. Drug Enforcement Administration, out of all the Schedule III or IV diet pills regulated by the CSA, Phentermine is the most widely prescribed and most frequently encountered on the illicit market today. This is not a surprise due to its effectiveness and difficulty in obtaining a prescription.

Does Phentermine work?

Phentermine’s effectiveness in promoting weight loss is definite, though modest and short-term.

Information from clinical trials proves that patients given this medication in addition to lifestyle modifications, such as reduced-fat diet and bodily exercises, lose about 2–4 pounds (4.4–6.6 lb) in a month.

To enjoy good results, it must be used together with a reduced-calorie diet and exercise.

We can also see some patients’ testimonials saying that they lost up to 10 pounds in one month, but those are the extreme cases.

Phentermine works only in the short term

Research has shown Phentermine can only boost weight loss in the short term. This is one of its main shortfalls.

Tolerance begins after six to eight weeks of use, resulting in the drug effects to decrease and appetite levels to return. This is when patients increase their food intakes leading to weight rebound.

This could be the main reason why the long term data on this appetite suppressant drug’s use shows no net weight loss.

This is the main reason why I don’t really fancy Phentermine. I mean, you use it, you lose weight in the beginning, just for two to three months.

After that, it loses its effects because your body system starts to tolerate it. Then you start to eat more and gain weight.

All your initial weight loss efforts are now gone and you are left with frustrations!

It follows that you have to start losing weight again.

This repetition serves no end to your weight loss program.

On this, it loses out to some of its alternatives, Phen375 and PhenQ; which are well proven to help users to lose weight and keep it off in the long term.

I think teaching people what to and what not to eat, how to control appetite better, how to exercise, and coupled with the use of the dietary supplement to lose and keep the weight off; would make a much better sense and more effective long-term strategy.

This is where both Phen375 and PhenQ has an advantage over Phentermine.

Is it safe to take Phentermine?

Phentermine is a Schedule IV drug.

Scientists say it is never safe to take the drug.

That’s why you need a doctor’s prescription to use it.

In reality, a small percentage of Phentermine users found they are perfectly okay with the medication. They experience weight loss without any unwanted effects at all. This is especially true when they follow strictly on the prescription given by their physicians.

Although some users are able to tolerate pretty well with Phentermine and are not affected by any adverse effects at all, losing weight with this anorectic drug can be quite dangerous. This is because it may cause many side effects.

Phentermine side effects experienced by patients

In fact, more than half of the patients using this medicine were affected by various bad reactions. I discovered this when doing a research on Phentermine users reviews online.

Most of the users experience common negative effects like insomnia, increase in blood pressure, irritability, abnormal heart rhythms, euphoria, and dizziness.

Some people reported that they suffer from side effects of Phentermine such as bizarre behavior, breathing difficulties, chest pain, decreased exercise ability, hallucinations, overactive reflexes, panic, and loss of consciousness with twitching or shaking of the body; though not that common.

There are also cases of serious allergic reactions such as swelling or blue lips or face, itchiness, hives, and rashes.

Side effects that are dangerous

Phentermine severe effects like palpitation, psychosis, seizures, and hypertension are so dangerous. They may be life-threatening when not treated properly.

Phentermine withdrawal side effects

Another problem with Phentermine is this medication is addictive and has withdrawal negative effects.

Evidence showed stop using it can lead to withdrawal effects such as physically or psychologically dependent on this medicine.

Change in sleeping patterns or personality were also seen.

The sudden shortage of this dietary drug may also make you feel depressed, frustrated and angry.

Note: Due to these many different side effects caused, many doctors are now very reluctant to prescribe Phentermine for their patients.

The occurrence of all these adverse reactions proves Phentermine is NOT safe for consumption!

In case you have no choice but to use it, make sure you know how to safeguard yourself of any such bad effects.

How to avoid Phentermine side effects

The best way to avoid or reduce the Phentermine unwanted side effects risks is to follow strictly on the prescribed dosing instructions.

If the effects make you feel uncomfortable in any case, don’t hesitate to consult with your doctor immediately.

Phentermine Reviews – Conclusion

Phentermine’s effectiveness in causing weight loss is definite, even though short range. In other words, it is a good short-termed appetite suppressant; but it is not the best weight loss drug.

The weakness about this medicine is it is not that safe to take.

It causes lots of side effects, ranging from the most common one like fever to dangerous life-threatening ones like pushing up of blood pressure to an abnormally high level.

For the purposes of this review, we’d rate Phentermine for 55/100.

Regardless of all its disadvantages, Phentermine is still a very good medication to help patients with high health risks to kick-start their obesity management program.

This is especially true if they have problems with appetite control.

If you do decide to lose weight with Phentermine, it is critical that:

  • you get a prescription from your doctor
  • buy the genuine product
  • take it under the supervision of a licensed physician
  • combine its use with a low-calorie diet
  • adopt necessary lifestyle changes

All these will give you a better chance of successful and safe weight management with Phentermine.
