Phentermine for Obesity, Weight Loss

My Bariatric Life Health Guide
  • How Phentermine Works


    Phentermine is an anorectic drug and appetite suppressant used to make people feel less hungry. It works by changing the levels of neurotransmitters affecting mood and appetite. Long-term use of this drug is not recommended because it works for only a few weeks.

    Phentermine is normally prescribed to those people who suffer from complications of obesity. It is usually prescribed for only three to six weeks and is a stimulant that increases fat metabolism while decreasing appetite. Phentermine can cause rapid heartbeat and an increase in blood pressure. Some patients report feeling dizzy or lightheaded when taking this drug.

    Phentermine and Weight Loss

    Phentermine is an appetite suppressant. The principle behind weight loss is to consume less calories per day than your body burns. This consumption causes a calorie deficit and your body must then burn its’ own fat for fuel. The result is weight loss.

    When taking phentermine, the amount of weight lost depends on a few things including age, gender, health, and level of exercise and diet. The goal is to lose one to two pounds per week which is considered an appropriate weight loss for long-term success.

    In addition, a diet consisting of 1200 calories per day should be maintained whereas that level is the minimum number required to sustain basic metabolic function.

    Is Phentermine Safe?

    There is some controversy in the medical community about using phentermine for weight loss. This drug is no longer marketed in Europe due to a possible association with heart and lung problems. In 1997, the combination of phentermine and fenfluramine was taken off the market after researchers at Mayo Clinic discovered it was linked with heart disease and pulmonary hypertension. The combination of the two drugs was known as “Fen Phen.”

    Before taking phentermine, your doctor should know if you are allergic to phentermine or any of the ingredients in phentermine. Make your doctor aware of any prescription or non-prescription medications you are taking as well as any nutritional supplements or herbal products you are taking.


    Your doctor should know if you have any history of heart disease, high blood pressure, arteriosclerosis, hyperthyroidism, diabetes, glaucoma, or history of drug abuse.

    Your doctor should know if you are pregnant, breastfeeding, or plan to become pregnant.

    Side Effects of Phentermine

    Some of the less serious side effects of phentermine are feeling restless or hyperactive, dizziness, insomnia, dry mouth, and diarrhea or constipation.

    Some of the more serious side effects of phentermine are shortness of breath, chest pain, swelling ion the ankle and feet, pounding heartbeats, confusion or irritability, unusual thoughts or behaviors, feelings of extreme happiness or extreme sadness, and dangerously high blood pressure.

    If you are experiencing any of these side effects, a doctor should be contacted immediately.

    Emergency medical help should be contacted if any of the allergic reactions of hives, difficulty breathing, or swelling of the face, lips, tongue, or throat presents.
