Phentermine.

Phentermine is a prescription appetite suppressant used to aid weight loss in adults who are overweight or obese. It is usually prescribed along with a reduced-calorie diet, exercise, and behavioral changes.

 How it Works

Phentermine is a central nervous system stimulant related to amphetamines. It works by:

• Increasing the release of norepinephrine in the brain
• Suppressing appetite, making it easier to reduce calorie intake
• Slightly increasing metabolism in some patients

 Common Medical Uses

• Short-term weight loss (usually prescribed for a few weeks)
• Part of a comprehensive weight management program for patients with BMI ≥ 30, or BMI ≥ 27 with weight-related conditions such as hypertension, diabetes, or high cholesterol

 Benefits

• Helps reduce appetite and food intake
• Can support modest weight loss when combined with diet and exercise
• May improve blood pressure, cholesterol, and blood sugar levels in overweight patients

 Possible Side Effects

• Increased heart rate, palpitations
• Elevated blood pressure
• Insomnia, restlessness, anxiety
• Dry mouth, constipation
• Rare: pulmonary hypertension or heart valve issues (mostly with long-term use or combination therapy)

 Important Precautions

• Short-term use: Typically prescribed for 12 weeks or less due to tolerance and side effect risk
• Cardiovascular risk: Not recommended for people with heart disease, uncontrolled hypertension, or history of stroke
• Drug interactions: Avoid combining with other stimulants, MAO inhibitors, or certain antidepressants
• Pregnancy & breastfeeding: Should not be used

 Summary

Phentermine is a short-term prescription appetite suppressant that helps promote weight loss when combined with diet and exercise. It can be effective but carries stimulant-related side effects and is not suitable for everyone, particularly those with cardiovascular conditions.

I can also make a comparison between Phentermine, Xenical, and Wegovy, so you can see how different weight-loss medications work and their safety profiles. Do you want me to do that?
