Phentermine 37.5 is a diet pill prescribed by a doctor. The medication, along with a reduced calorie diet and an active exercise program, have been proven to help people lose weight. Phentermine is recommended for people who are obese and haven’t been able to shed pounds with exercise and diet alone. Losing weight and keeping the pounds off can reduce a number of health risks, including diabetes, high blood pressure and heart disease.
Phentermine works by changing the amount of serotonin in the brain, which helps to suppress the appetite. The diet medication also raises the metabolism and prompts the body to use food as fuel instead of fat.
The medication should be taken orally as directed by a physician. In most cases, the dosage is once a day, either an hour before breakfast or two hours following breakfast. If you’re taken the form of phentermine that dissolves in the mouth, it’s best to take the medication once a day, in the morning. Dissolving tablets can be taken with or without food. Sustained-released capsules should be swallowed whole, as crushing the pill before taking it could intensify side effects. If phentermine is taken later in the day, insomnia can result.
Phentermine is prescribed based on an individual’s medical state and response to other forms of weight loss therapy. Physicians will often adjust the dosage according to the patient. Phentermine should be taken exactly as prescribed for best results.
Phentermine is not a permanent solution for weight loss, and should only be taken for a few weeks at a time. Patients who are taking phentermine should not take any other appetite suppressants. Taking phentermine longer than a couple of months, or using the prescription along with other diet pills, could result in severe side effects such as migraines, irregular heartbeat, slurred speech or muscle weakness on one side of the body. However, these side effects are rare and are often a result of medication misuse. Individuals with anxiety and bipolar disorder should consult their doctors before taking phentermine.
Other minor side effects include irritability, dry mouth, nausea and constipation. These symptoms usually disappear once a patient’s body becomes accustomed to phentermine.
