Is there anything I need to know before I take Phentermine?


Before taking phentermine
Do not take phentermine if you have used an MAO inhibitor such as isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate) within the past 14 days. Serious, life-threatening side effects can occur if you take phentermine before the MAO inhibitor has cleared from your body.

Phentermine should be used as a short term drug to help patients to start losing weight while the patient is undergoing permanent long term changes in their attitude towards food and exercise. The body starts to build up a resistance to the effects of Phentermine after a few weeks of treatment, by which time the patient should be well on their way to a new lifestyle and ready to stop taking Phentermine while continuing to maintain a healthy weight on their own. Taking Phentermine is not a substitute for proper diet. For maximum effect, Phentermine must be used in conjunction with a diet and exercise program.
