Phentermine.

Phentermine is a prescription medicine that has been specially designed for patients that are obese and unable to get rid of the excessive weight by following a diet and getting regular exercise. Do not exceed the dose prescribed or take phentermine more often than recommended to avoid health complications. You will be most probably recommended to take this medicine three times a day about 3 minutes before having a meal, although a single dose is also possible. If you happened to miss a dose – make sure you take it as soon as you remember. Avoid taking a double dose if it's almost time for the next one – that way you are not going to get better results. You also need to be aware of the possibility of getting some side effects that can vary in intensity. Such side effects as dry mouth, constipation, unpleasant taste, vomiting, and diarrhea are considered to be mild and do not need to be reported to your health care provider. More serious side effect are quite rare and can include shortness of breath, tremor, insomnia, chest pain, restlessness, heart palpitations, increased blood pressure, and dizziness. Make sure you always keep your health care provider updated on the drugs you are taking, especially if you are using such meds as fluoxetine, tranylcypromine, insulin, depression, guanethidine, fluvoxamine, MAO inhibitors, weight loss meds etc to prevent interactions.
