Phentermine is an appetite suppressant that works by affecting the central nervous system, reducing hunger, and promoting feelings of fullness. It is normally taken once a day, alone or sometimes with other weight loss medication(s).
Phentermine is FDA approved for short term weight management (typically 3-6 months at a time, followed by a 3–6-month break). It is classified by the DEA as a schedule IV-controlled medication, meaning there is a low to moderate potential for abuse.
In other words, after about 6 months of use, the medication can be habit forming, which is why it is only prescribed for 3-6 months at a time, followed by a break. Patients also notice that after a few months of taking phentermine, they build up a tolerance to the medication, so while it works great to suppress your appetite in the first 2-3 months, it becomes less effective after that.
At Pure Medicine, Dr. Pastorek requires monthly visits while on phentermine due to the controlled nature of the prescription, so he can monitor your weight loss, vital signs, and help mitigate any ongoing side effects. Many patients opt for telemedicine visits for their monthly check-ins (requires the ability to check blood pressure/pulse/weight at home to submit for the appointment).
Depending on risk factors, some patients may require cardiac clearance (EKG, calcium scoring, stress testing, and/or blood pressure logging, and some may possibly need an official clearance by a cardiologist).
Dr. Pastorek recommends the following strategies while you are taking phentermine:
Typical side effects from phentermine (more noticeable the first few days of use) include:
Most patients notice the dry mouth, and a significant percentage of patients need melatonin or other medication to help with their insomnia. Constipation is usually addressed by use of magnesium supplementation (titrated as needed) and stool softeners.
This medication is not for everyone. Those with cardiac arrhythmias (fast/irregular heartbeats), uncontrolled high blood pressure, substance abuse disorders, severe anxiety, and those who are at high risk for stroke or heart attack, may not be candidates for phentermine.
For those who are not a candidate for phentermine, there are other medical weight loss options available.
