Phentermine is intended to help the heavily overweight to regain control over their weight.
Phentermine is prescribed for people who have a BMI (body Mass Index) of 30 or greater or for people that have a BMI of 27 or greater and suffer from other associated risk factors such as high blood pressure, diabetes or hyperlipidermia.
Normally doctors will only prescribe phentermine to a patient if the patient has demonstrated that they have already made adjustments in their lifestyle in an attempt to lose weight but have been unsuccessful in lowering their weight.
Before taking phentermine your doctor should be aware of your medical history. Inform your doctor of all medications, both prescription and non-prescription, that you are taking or have taken recently.

- Taken an MAO inhibitor within the last 14 days
- A known allergy to phentermine or other stimulants
- Heart disease or hypertension
- An over active thyroid
- Feelings of increased tension, anxiousness and/or irritability
- A history of alcohol or other drug abuse
It is important to tell your doctor if you have suffered from any of the following:
- Thyroid problems
