When it comes to weight loss, phentermine is a popular and much used drug. You will find phentermine in many forms and names, some examples of which are Fastin, Zantryl, Adipex, Adipex-P, Teramine and Suprenza. Another thing to know about phentermine is that since it has a molecular structure like that of amphetamines, it is considered that its use can lead to addiction and thus abuse and overdose. That is why, in many countries, it is a Schedule IV drug, which means, its sale and use is controlled. Yet, phentermine is medically found to be very effective in aiding in weight loss and that is why bariatric specialists recommend the drug to their patients but under supervision.
The right dosage of phentermine
Phentermine works by stimulating norepinephrine release. The dosage advised is different for different people and it would depend on the person’s level of obesity as well. Phentermine is an appetite suppressant but even when doctors advise its use, the patients are always asked to follow a diet low in calories. Yet, doctors advise it only to really obese patients whose weight is becoming a risk factor for their health.
Since phentermine can induce addiction, it should be used only for a short-term. The dosage in addition to be different for each individual, it also depends on the brand. The dosage level of capsules and tablets may be different as well. The tablets and capsules of Adipex-P and Suprenza come in 30 mg and 37.5 mg respectively. The dispersible tablets are available in different forms such as 15 mg, 30 mg and also 37.5 mg. Phentermine hydrochloride-topiramate which is a new phentermine drug in market, is advised with different dosages.
The review of phentermine
There are many positive reviews of phentermine. Reviews point out to the dual role of phentermine, as that of an appetite suppressant and that of nerve cell transmission enhancer. Some time ago, amphetamine drugs were used for controlling obesity as they were very effective in weight loss but now studies are published that point to their negative effects.
Phentermine is no doubt effective in weight loss but they have to be taken under medical supervision along with nutritious and low-calorie diet. Also, since it is a controlled drug, it is sold only under prescription. Phentermine helps in controlling hunger which means no intake of excess calories and it also helps in spending energy. This means no fat accumulation.
Yet, its usage has to be with caution due to the side effects associated with it, which include nausea, dry mouth, constipation, vomiting and diarrhea. Headache, insomnia, dizziness are other symptoms. Hence, it is advised that phentermine should be taken only under doctor’s guidance.
Though FDA has approved orlistat and sibutramine as effective drugs for obesity treatment, they are sold only with a prescription. Also, note that these drugs do help in weight loss, but it was also found that there is a tendency to put on weight again after its use has been stopped. Also, any weight loss supplement works only when it is combined with good exercises and nutritious diet.
