Consumer medicine information (CMI) leaflet
Please read this leaflet carefully before you start using Metermine.
This Consumer Medicine Information (CMI) is intended for persons living in Australia.
Why am I taking Metermine?
Metermine contains the active ingredient phentermine. Phentermine is combined with a resin which slowly releases the phentermine, so the effect of Metermine lasts all day.
Metermine is used to reduce body weight in obese or overweight patients.
Metermine is an appetite suppressant that works by directly affecting the area of the brain that controls your appetite, making you feel less hungry.
Metermine should be used as a part of an overall weight management plan, which includes a medically controlled diet and exercise program.
Your doctor will assess whether Metermine is suitable for you. Calculation of the body mass index helps to do that.
BMI is calculated by dividing your weight in kilograms by your height in metres squared.
Enter your measurements and click ‘calculate’ for your body mass index.
If your BMI is above or below the normal range but you consider yourself to be of normal and healthy weight for your height, chat with your doctor about any potential health concerns.
This calculator has been reviewed by NeverGiveUpTeam experts and is based on reputable sources of medical research. It is not a diagnostic tool and should not be relied on as a substitute for professional medical or other professional health advice.
