Doctors prescribe diet pills that control hunger for people with problems related to chronic obesity, according to information provided by the Weight-Control Information Network, a National Institutes of Health website. These medications produce quick weight loss to relieve dangerous health conditions like diabetes and high blood pressure. Patients must meet specific criteria including a body mass index of 30 and above. To use prescription appetite suppressants as directed, take them in conjunction with a diet and exercise program recommended by your health-care professional.
Sibutramine
Diet pills with sibutramine are appetite suppressants, according to the Weight-Control Information Network. Available by prescription only, the safety of this long-term hunger controlling diet drug is in question. According to a clinical trial performed by the Boden Institute of Obesity, Nutrition, and Exercise and the University of Sydney along with other universities and published in the September 2010 issue of the "New England Journal of Medicine," ingestion of sibutramine resulted in an unexpected increase in the risk of nonfatal heart attack and stroke in patients with preexisting cardiovascular disease. However, the same trial found participants taking sibutramine experienced modest weight loss.
Phentermine
Phentermine is a diet pill, intended for short-term use, which works by suppressing your appetite, according to the Weight-Control Network. This prescription medication may be habit forming and side effects may be reduced by taking your dose with meals, advises Medline Plus, a National Institutes of Health website. It cautions phentermine may react negatively with prescription medication and dietary supplements including MAO inhibitors, insulin and vitamins. Mild side effects include unpleasant taste, dry mouth and constipation. Serious side effects reported with phentermine use include increased blood pressure, tremors, chest pain, dizziness and swelling of the legs.
Phendimetrazine
Diet pills with phendimetrazine control hunger by suppressing your appetite, according to the Weight-Control Information Network. Phendimetrazine is similar to an amphetamine and decreases your appetite by increasing your heart rate and blood pressure, explains Drugs.com. This prescription diet pill, intended for short-term use, may not be suitable for people with pre-existing conditions including glaucoma, heart disease, high blood pressure, epilepsy, diabetes or a history of substance abuse. The most serious side effects reported with phendimetrazine, as listed by Drugs.com, are irregular heartbeat, very high blood pressure, hallucinations and abnormal behavior. Less serious side effects are more likely to occur and include tremors, anxiety, headaches, insomnia and impotency. Phendimetrazine is habit forming and Drugs.com warns patients may become physically and psychologically dependent.
