To be on the safe side, always inform your doctor in case you are suffering from any chronic health problem such as hypertension, diabetes, thyroid dysfunction etc., so that he or she can weigh the benefits and the risks before deciding to prescribe you with phentermine.

Phentermine should not be taken by pregnant or lactating women, as well as children and adolescents younger than 16 years old.

Important Information when Taking Phentermine

Phentermine should be accompanied by a healthy diet plan and regular workouts. It is especially recommended for those people who suffer for co-morbid conditions besides obesity, such as hypertension, high cholesterol and abnormal blood sugar levels or diabetes. Nonetheless, many doctors use this drug for unlabeled indications as well.

Avoid taking this drug if you are on a MAO inhibitor such as Marplan, Furoxone, Azilect, Nardilm, Eldepryl and Parnate currently or during the past couple of weeks. If you ignore this advice and coadminister phentermine with a MAO inhibitor, you risk a dangerous interaction which may result in serious adverse effects.

When taking phentermine, avoid ingesting any other diet medication at the same time. Some weight loss supplements may induce fatal lung issues if taken together with phentermine. So remember to never do it, unless it is your doctor’s order.

When not taking this drug as indicated, there is a chance to alter one’s perception of reality, therefore extra caution is required when driving or doing any activity that required total focus. You should absolutely avoid drinking alcohol when using this drug, as it may increase the incidence of adverse effects.

It is important to remember that phentermine is only a small part of the entire weight loss plan. As such, it works in tandem with other elements of a weight loss regimen, such as a healthy eating plan, regular physical activity and weight monitoring. By no means is phentermine poised to handle the entire weight loss burden. In order to get the best results, strict adherence to the entire program is required.
