  • Is the diet pill Phentermine safe?

    Prescription diet pills are intended for use by people whose BMI exceeds 30 and are therefore classed as obese. People that have a BMI of 27 or greater and that also suffer from associated risk factors such as hypertension, diabetes or hyperlipidemia are also often deemed suitable candidates for phentermine.
    It is true that prescription diet pills, like all other medications can cause side effects, however when someone is prescribed a diet pill such as phentermine it is because your doctor feels that the benefits of losing weight to reach a healthy BMI outweigh the possible side effects.

    The side effects of phentermine diet pills will vary from person to person, some people experience little to no side effects whilst using phentermine.
    Those who do initially experience side effects find that they lessen after the first few days of taking the phentermine diet pills as their body becomes accustomed to them. If whilst taking phentermine diet pills you experience chest pains, difficulty in breathing, fainting, swelling of the feet or lower legs or feel concerned about a possible side effect consult your doctor immediately.

    Phentermine diet pills have been approved by the FDA (Food and Drug Administration) for short term use of no longer than three months. This means that the FDA have found phentermine to be a safe and effective obesity management aid. Phentermine should be taken exactly as your doctor prescribed them to you.

  • Do prescription weight loss drugs work?

    Yes, prescription weight loss drugs do work if used correctly.

    One of the common criticisms of prescription weight loss drugs is that patients regain the weight they originally lost once they stop taking the diet pills. Prescription weight loss drugs should be used as a tool to help people adopt healthier diets and exercise programs that they can maintain for the rest of their lives. Of course if you return to the diet and exercise habits that you had before you started taking the prescription weight loss drugs, over time you will regain the weight you lost.

    One drawback that all medications, not just prescription weight loss drugs, suffer is the possibility of side effects. Prescription weight loss drugs that are FDA approved such as phentermine and Xenical are considered to have a positive affect on weight loss and be safe to use. However, each person’s body reacts differently to medications and some people may experience more or less severe side effects from prescription weight loss drugs than others. Some people may find that their body does not tolerate a particular prescription weight loss drug well and may be advised to switch to try a different one. Your medical history should always be taken into account before your doctor agrees to prescribe prescription weight loss drug for you. Once you have started taking the diet pills your progress and reaction to the drugs should be closely monitored by a health professional.

    Phentermine is the most popular and commonly prescribed diet pill in the US.

    Approved in 1959 by the FDA doctors have been prescribing phentermine to their overweight patients for decades. Its long record as an appetite suppressant that is safe to use, with tolerable side effects and that actually produces significant weight loss is how phentermine has come to be thought by many to be the best diet pill available on the market today.

  • Is phentermine better than using, i.e., hydroxycut, metabolife, and body solutions?

    This really depends on your medical history, and how your body reacts to the different medications mentioned, and if the medication is most suited to your needs. Phentermine should NOT be taken if you have any of the following conditions: heart disease, high blood pressure, glaucoma, thyroid problems, anxiety disorder, diabetes, epilepsy or any other seizure disorder. Do not take Phentermine if you are taking monoamine oxidase inhibitors (MAOI) to treat depression. Also, if you are pregnant or nursing, talk to your doctor about the potential risks involved with taking Phentermine.

    The success of Phentermine as a weight loss drug is probably due to the fact that it is one of the oldest FDA approved weight loss drugs in the market, and because it is cheaper than other diet pills. Phentermine pills’ advantages are seen mostly among those who suffer from severe obesity. This medication is administered primarily to those who have followed healthy eating and exercise regimens, yet cannot get to a healthy weight. This pill can be the answer for these people.

    Taking Phentermine, along with eating and exercising sensibly, can be the answer for those who suffer from obesity.
