Please be aware that the Medical Professionals at Resolve do not prescribe phentermine to our patients due to concerns around long term effectiveness for weight loss, increased risk for cardiovascular events and potential for drug abuse and dependence. The information below is for your education only.

What is phentermine?

Phentermine is a medication classified as an “anoretic” medication, meaning it helps you lose weight, and has been an FDA approved medication since 1959.  Simply stated, phentermine stimulates the brain to increase activity of the sympathetic nervous system.  In doing so, appetite is suppressed and cravings are decreased, while metabolism is increased. The medication lasts about 10-12 hours in most patients and is usually taken in the morning. Phentermine is only approved for short-term use and has a risk for increased tolerance (having to take more of the medication to get the same effect), abuse and dependence. It is classified by the DEA as a controlled substance and can only be obtained with a prescription from a doctor.

What are the side effects?

Side effects related to phentermine include insomnia or trouble sleeping, feeling jittery or anxious, dry mouth, dizziness and headache.  If you have high blood pressure or other cardiovascular condition this medication can cause it to worsen.
