PHENTERMINE - DRUG FOR WEIGHT LOSS
Phentermine is a centrally acting, catecholaminergic drug that produces a decrease in appetite that can help patients decrease their food intake. After being swallowed it produces peak plasma concentrations within 8 hours and its therapeutic effect might last for 20 hours.
Phentermine has mild to moderate stimulant properties and its side-effects are related to this: headache, dry mouth, constipation, fast pulse, sweating and restlessness. The dosage is usually 15 to 30 mg, taken each morning. Withdrawal effects can lead to depression and lethargy.
There is no published literature to suggest that phentermine results in drug dependence, particularly if used for no more than the licensed 3-month period. However, there is little evidence to support the use of phentermine beyond 3 months as there are insufficient recent data to support its efficacy and safety beyond a 3-month period. It is therefore difficult to justify routine use of phentermine as it is commonly considered that 3 months drug treatment is insufficient to produce meaningful and sustained weight loss with supported lifestyle change.
