The search for a good dieting aid brings to the table a product known as phentermine. After sifting through countless phentermine reviews and extensive research work, the following came to light. First things first Phenyl-tertiary-butyl-amine, i.e. phentermine is a prescription-only psychostimulant that works to curtail appetite and treat obesity. It is organic in nature and is intended as a weight loss aid to be accompanied with workouts and diets.
Phentermine was initially approved as an appetite-suppressant when it first graced the market in 1959 to pair weight loss drug Fenfluramine. This popular combination, however, was substantiated to instigate heart valve disease due to the Fenfluramine so the makers removed the compound from the formula and repacked Phentermine on its own. In 2012, Vivus paired phentermine with topiramate to come up with an obesity and weight loss solution. This new combination, unlike its predecessor, was given the green light by the FDA.
What Phentermine Says It Does
According to extensive studies and phentermine reviews, the drug works to alter the functioning of neurotransmitters responsible for controlling appetite thereby regulating hunger. Also, it triggers the increased production of adrenaline thus providing energy spikes hence why it is incorporated into workout routines. Its classification as an amphetamine means the drug is available only on a doctor’s prescription.
The product is basically a compound. It is made through a process known as the Henry reaction where 2-nitropropane and benzaldehyde interact to create an amino-alcohol. The latter is then imbued with thionyl chloride and the resulting product reduced using hydrogen to form the compound we know as phentermine.
Is Phentermine effective?
Going by the many positive phentermine reviews and the feedback of countless weight loss experts who purport it’s a great way to mitigate appetite while keeping energy levels high, then yes, it is very effective. So much so that it has been categorized as a controlled substance to prevent people from taking advantage of its potency. Phentermine varies in design from one provider to the other. However, its overall working is generally a mainstay.
The companies who supply the product include:
- Kwang Dong
- Gate Pharmaceuticals
- Laboratorios Recalcine
Results and Benefits of Phentermine
Heaps of phentermine reviews point to the fact that it is a slow-working compound that guarantees significant results. Weight loss is something that doesn’t occur overnight and there is nothing wrong with the compound taking some time to produce results. However, when coupled with the right exercises, diet and correct dosage supervision, everybody agreed that the results were exceptionally good. From over 2300 phentermine reviews on drugs.com, the FDA-approved compound amassed an impressive 8.8/10 rating which is a testament to its potency.
Phentermine can be paired with other drugs or can be used exclusively on its own. Either way, a prescription is required nonetheless. Ingestion methods vary from one manufacturer to the next and also according to doctors’ advice. In general, a dosage is recommended once in 24 hours and on an empty stomach. It should not be taken before bedtime given its ability to interfere with a number of neural pathways which can result in sleeping difficulties.
While dosage specifications ought to be outlined by a medical expert after a patient’s assessment, the general rule of thumb is a dosage of between 15-37.5 mg. This should be taken at least an hour, but no more than 2, before a meal. For adults below 60, the appropriate time is before breakfast. Children under 16 years shouldn’t use the product. Others to also steer clear of the drug include pregnant women, people living with diabetes and those on other prescription medicine except if advised otherwise by their doctor. Phentermine should also not be taken alongside alcohol given the pair’s ability to induce dizziness.
Increasing dosage should only be done as per doctors’ advice given that the severity of effects also increases with an uptake of the compound. Withdrawal from Phentermine, on the other hand, should be done gradually by reducing the daily dosage slowly so as to enable the body to adapt to the new changes.
Possible Side Effects
Given phentermine is a member of the amphetamine family, its side effects are similar to chemicals of that class and they include:
- Increased blood pressure
- Dry mouth
- Stomach upsets
Final verdict: Hit or miss? Phentermine reviews are promising, and the product’s longevity is also commendable. However, that there exists only proof for benefits on the short-term is a bit worrying. Also, there are a couple of users who have noted negative side effects which brings us to the bone of contention: does phentermine really work? Well, the jury is still out on this one, however, a cautious yes seems to be the ideal answer to that question.
