Phentermine is a prescription medication used for weight loss and to help manage obesity. It works as an appetite suppressant, aiding individuals in reducing their food intake. Phentermine is typically prescribed for short-term use, alongside a doctor-approved exercise, behavior change, and reduced-calorie diet program. It is intended for individuals who have not been able to lose enough weight with diet and exercise alone and who have weight-related medical problems such as high blood pressure, high cholesterol, or diabetes.

Common side effects of phentermine include dry mouth, insomnia, dizziness, increased heart rate, and nervousness. These effects often lessen as your body adjusts to the medication. However, if any side effects persist or worsen, it is crucial to contact your healthcare provider promptly.
