What Is Phentermine?
Phentermine, often sold under the brand names Adipex-P, Oby-Cap, T-Diet, Lomaira, or Zantryl, is a stimulant which acts on the central nervous system (similar to an amphetamine) to suppress appetite. First developed in 1959, Phentermine has been prescribed to patients who generally have a medical need to keep their weight down (particularly obese patients with comorbidities). Phentermine is used as an appetite suppressant for short-term weight loss programs—it’s typically only prescribed for a four-to-six-week duration. When combined with a low-calorie diet, daily exercise regimens, and behavioral changes, Phentermine can result in quick weight loss.
Benefits of Phentermine
Phentermine is used as a weight loss medication due to its ability to reduce hunger and caloric intake while instilling a feeling of fullness. Doctors usually recommend a Phentermine weight loss plan for patients with obesity or individuals with certain health risks linked to being overweight, like high blood pressure, high cholesterol, and diabetes. Because they’re primarily used to lose weight, Phentermine diet pills can also minimize susceptibility to weight-related medical problems such as heart failure, heart disease, stroke, gout, certain types of cancer, and cardiovascular disease.
Research proves the effectiveness of Phentermine and its ability to speed up weight loss—the average expected weight loss when using Phentermine is 5% of your initial body weight over a four-to-six-week duration. If you take Phentermine for an extended 12-week program, you can lose up to 10% of your initial body weight (about 10-20 pounds for a 200-pound person).
Is Phentermine Safe?
Phentermine is only considered safe to use on a short-term, doctor-supervised basis. It is a controlled substance, and you should discuss any preexisting medical conditions with your physician before taking it. You are not considered a good candidate for a Phentermine diet plan if you have heart disease, uncontrolled high blood pressure, an overactive thyroid, allergies to stimulants or appetite suppressants (like amphetamine or diethylpropion), mental or mood disorders (like anxiety, bipolar disorder, or depression), or have a history of substance abuse.
It’s crucial to discuss all medications you are currently taking with your doctor to ensure there are no adverse drug interactions when you begin taking Phentermine. You should be especially cautious when taking Phentermine if you have diabetes, as you may need to adjust your diabetes medication during treatment if your doctor advises. The medication should not be used during pregnancy, and you should stop taking it immediately if you think you may be pregnant. If you use Phentermine longer than directed, you are at a higher risk for developing serious health problems, including heart palpitations, dizziness, edema, shortness of breath, primary pulmonary hypertension, and valvular heart disease.
