Phentermine for Weight Loss

Phentermine for Weight Loss

As studies for chronic obesity continue to evolve, one thing that hasn’t changed is the importance of diet and exercise. But unfortunately, despite all the hard work at the gym and diligent efforts to eat healthier, many patients who suffer from obesity still have trouble losing weight. In fact, according to, 1 out of three patients usually end up regaining their unwanted weight after 5-6 months, which is generally the time frame where they should be losing 5 to 10 percent of their weight.

Over the years, certain OTC weight loss drugs have provided patients a much-needed advantage in helping them lose and manage their weight. Unfortunately, although these weight loss alternatives boast that they can produce a significant decrease in body fats and longer-lasting results in weight management, many fall short of expectations and are usually full of unnecessary additives that are unhealthy to the body. And since these medications are broadly used for everyone, many patients find themselves experiencing serious side effects as each of their unique body types react differently to the weight loss drugs.

What is Phentermine?

Phentermine (also known as Adipex-P) is an appetite suppressant that was first approved for weight loss by the FDA in 1959, making it the oldest weight loss medication used today. It was first used to help provide short-term weight loss treatment of 12 weeks or less.

How Does Phentermine Work for Weight Loss?

Phentermine is an anorectic that works to decrease hunger by triggering the release of neurotransmitters (norepinephrine, serotonin, and dopamine) to the part of the hypothalamus that controls appetite. As the level of chemical neurotransmitters increases and affects your central nervous system, your desire to overeat decreases.

However, patients using Phentermine as an appetite suppressant may build a tolerance after long-term use, so a physician may need to make adjustments to the prescription for patients to attain the best Phentermine weight loss results, making this an inferior solution.

Who Are The Best Candidates To Take Phentermine For Weight Loss?

Typically, overweight and obese adults with a body mass index (BMI) over the 27- 30 range dealing with other weight-related conditions such as hypertension and diabetes are the only candidates who should take Phentermine as a weight loss drug, if you’re looking for more sustainable weight loss other options are available.

Is Phentermine For Weight Loss Safe?

The FDA approved Phentermine as a safe short-term weight loss medication, while Phentermine-Topiramate has been proven effective as a long-term treatment for a year or more. However, patients should avoid taking Phentermine if they:

  • Have a cardiovascular disease
  • Are sensitive to stimulant drugs
  • Are taking monoamine oxidase inhibitors
  • Have a history of substance abuse

Phentermine Side Effects

As it is with every medication, using Phentermine weight loss pills can cause common side effects, which include:

  • Increased heart rate
  • Constipation
  • Dry mouth
  • Sleeplessness
  • Nervousness
  • Tingling in the hands and feet

Malnourished or severely ill adults may experience breathing problems after using Phentermine. In some cases, patients taking Phentermine have also reported experiencing headaches as their bodies adjust to the treatment. Therefore, your physician may recommend that you use caution when driving or performing other hazardous activities until you know how Phentermine affects you.

Frequently Asked Questions

If possible, take the dose as soon as you can remember. However, if it is too late in the day, skip the missed dose altogether to avoid taking two doses in less than 24 hours.

Patients may feel a sense of tiredness or fatigue as Phentermine may cause periods of overstimulation which may lead to sleepless nights. Other side effects of Phentermine may also include drowsiness and low energy levels. If you feel fatigued or have a drop in energy from taking Phentermine, you should consult your physician immediately, as the symptoms may be a sign of an underlying medical condition.

Phentermine is typically prescribed as a part of a weight loss plan that incorporates exercise and a fat-burning diet, so you must take Phentermine for at least 12 weeks to achieve the best weight loss results. However, some results may vary depending on the patient’s body type, dieting, and exercise regimen.

For rapid weight loss with Phentermine, physicians recommend eating a high protein diet and a healthy amount of fiber. You should also incorporate increased intakes of fruits, vegetables, vitamins, minerals, and other nutrients to round out the diet. It’s also important to stick to a standard exercise regimen, drink plenty of water, and get adequate sleep so that your body can recover and burn more fat during the weight-loss program.

Nice and easy. I decided to use both services, the testosterone and sermorelin treatments. The biggest improvement I see so far is the recovery time between workouts. I am less sore and have seemly endless energy. Only a few months in, but so far, so great

The team at Renew Vitality is amazing. I have worked with multiple doctors both in the UK and State Side, this group represents what I consider to be best in class. I have nothing but praise for Dr. Marshall. I am a guy on the go and I will tell you that Nick on their team takes phenomenal care of me, it's like having my own personal concierge service 24/7. My only feedback would be....Don't ever lose Nick or I will have to go wherever he does. Thanks again!
