Drugs used in Weight Loss



Phentermine is an appetite suppressant that works on the hypothalamus to release norepinephrine, which in turn, decreases your appetite. Best results seen when used in conjunction with healthy diet and exercise. Not indicated for certain medical conditions.

Do I Qualify?

Normal BMI range is 18.5-24.9. Must have a minimum BMI of 30 or waist circumference of 37 inches for women or 40 inches for men , or a contributing health problem such as high blood pressure or heart disease to qualify for initiation of therapy. Medication will be tapered off after BMI returns to optimal range or less than 22.

Is Phentermine a good way to lose weight?

For years it was the only way to lose weight. It is a drug that mimics the fight or flight response and puts your body in a state of stress by releasing epinephrine and norepinephrine. It is not inherently bad and when used appropriately it works well. However, due to the stress response, it is only effective for a few months at a time and comes with some side effects. Namely, difficulty sleeping, heart palpitations, dry mouth and increased blood pressure. The newer class of medications below is a much better option for most people. 


GLP-1 Weight Loss Medications.

Semaglutide is a once-weekly injection that works by mimicking a hormone called glucagon-like peptide-1 (GLP-1) that targets areas of the brain that regulate appetite and food intake, this in turn causes slowing of gastric (stomach) emptying & making you feel full longer. A decrease in just 500 calories per day can result in 1 pound of weight loss in a week.

Tirzepatide is the newest drug in this class.   Click to learn more about   GLP-1 meds like tirzepatide and  weight loss options.
