WHAT IS PHENTERMINE
Phentermine is a prescription medication used primarily for weight loss. It was approved by the FDA in 1959 for short-term use of up to 12 weeks. In the 1990s, phentermine was combined with other weight loss drugs reported to cause heart problems.
Phentermine has several brand names including Adipex-P, Lomaira, and Suprenza. It can also be found in combination with topiramate and is branded as Qsymia. It’s a controlled substance due to its chemical similarities to the stimulant amphetamine — making it available only with a prescription. Your doctor may prescribe phentermine if you have a an elevatded BMI.
HOW DOES PHENTERMINE WORK
Phentermine is considered an appetite suppressants. Taking phentermine helps suppress your appetite, thereby limiting how many calories you eat. Over time, this can lead to weight loss. In addition, it increases energy and helps promote activity.
While the exact mechanisms behind the appetite-reducing effects of phentermine remain unclear, the drug is thought to act by increasing neurotransmitter levels in your brain. Neurotransmitters are your body’s chemical messengers and include norepinephrine, serotonin, and dopamine.When your levels of these three chemicals increase, your feeling of hunger decreases.
IS PHENTERMINE EFFECTIVE FOR WEIGHT LOSS
Several clinical studies have proven that phentermine can boost fat loss. Some studies show an expected average weight loss with phentermine use is 5% of your initial body weight. Many others have seen as high as 10% over a 12 weeks course of therapy. The amount of weight loss can be increased with increasing exercise to promote fat burining. Many practitioners combine therapies to promote the best and fastest results such as adding caloric restriction, MICC and B12 injections. Promoting optimal sleep helps the body recover and ready for the next day
While phentermine has been shown to be effective for weight loss, it may work better when combined with topiramate.Topiramate is a drug that has been used on its own to treat seizures but — like phentermine — also has appetite-reducing properties. Topiramate and phentermine is a combination medication sold under the brand name Qsymia.
Compared to three other commonly prescribed drugs for weight loss, the combination of phentermine and topiramate was associated with the highest odds of losing at least 5% of the initial body weight.
What’s more, research suggests that the phentermine and topiramate combination is the most effective weight loss medication to date — with people achieving an average weight loss of 21.6 pounds after taking the maximum dose.
In users, this weight loss has translated to a significant decrease in waist circumference, improved insulin sensitivity, and blood sugar control, as well as favorable effects on triglyceride and cholesterol levels
