Phentermine is a prescription drug given by physicians to patients who are significantly overweight. Only a physician can prescribe these drugs after carrying out an examination of the patients� history. The doctor may therefore require that the patient discloses any pre-existing conditions that he may be suffering from as well as any medication they could be on. The prescription is only for persons who may be required to lose over 20 pounds in order to avoid problems related to being overweight such as high blood pressure and diabetes. Persons who may not be required to lose more than 20 pounds will be likely to encounter problems such as fatigue, bloating, gas, constipation and their skin might look unhealthy should they use this drug in an attempt to lose weight.
Phentermine is used for short periods of between three and six weeks since it is habit forming. Persons who do not have any serious problems with their weight are therefore advised against using the drug. For instance patients who do not require losing more than 20 pounds are therefore advised to settle for alternative ways to lose weight. The best non-prescription alternative to Phentermine is Phentramin-d. In addition persons on other kinds of medication may be required to first complete their dose and that such medication is flushed out of their system before they can take phentermine. This will ensure maximum performance of phentermine. In addition persons who are given the prescription are advised not to take more than the prescribed quantity to avoid addiction to the drug. Further when they have failed to take the prescribed dosage they are advised to take as soon as they can.
Persons suffering from other conditions such as a history of alcohol or drug abuse may be required to disclose such conditions to their physicians so that they can determine if phentermine would aggravate their condition in which case the physician will prescribe a different drug. For diabetic persons, a higher dosage of insulin may require to be administered after they have used phentermine. A patient using phentermine should not combine it with any other weight loss agents since this may cause high blood pressure and other related ailments. Pregnant women are advised against using phentermine while no conclusive research has been done concerning nursing mothers using the drug.
Patients who may have at any one time suffered from stress and/depression at any one time may be required to discuss other options available to them with their physician as using phentermine may increase the health problems they might be experiencing currently. Persons who intend to use phentermine are advised to discuss with their physicians on their general health as well as family history to ensure that they qualify to use the drug. The patients in this case are required to be honest with the physician to avoid any serious side effects arising due to any other pre- existing patients� conditions. The patient and physician must therefore carefully evaluate the benefits and risks posed by the use of phentermine 37.5.
