FDA approved drugs for weight loss

There are several prescription medications that have been approved by the FDA for weight loss. Prescription medications are designed to be used along with a diet and exercise to maximize the amount of weight loss over a certain period of time. Most of these types of medications have been approved for short-term use only. The two exceptions are Meridia and Xenical. They have been approved for long-term use in obese people who would medically benefit from weight loss.

The other FDA-approved weight loss medications are Tenuate, Sanorex, Mazanor, Bontil, Plegine, Prelu-2, X-Trozine, Adipex-P, Fastin, Ionamin, and Oby-Trim. All these medications, with the exception of Xenical, function as an appetite suppressant or increase the feeling of satiety in the person taking it. These medications increase serotonin or catecholamine, which are two chemicals in the brain that affect both mood and appetite.



Some of the drawbacks of taking medications that are appetite suppressants are the possibility of dependence or addiction and the development of a medication tolerance. Some of the milder side effects are anxiety, insomnia, headaches, and feelings of euphoria. The most serious side effect that has been observed is the increased risk of pulmonary hypertension. People who have had a history of heart disease, irregular heartbeat, high blood pressure or stroke should not take these medications.



Xenical is the only drug of its kind approved by the FDA for weight loss. It works as a lipase inhibitor. This decreases the body's ability to digest and metabolize the fats that are ingested. Then, the body excretes fats in the stool. As indicated above, it is one of two FDA-approved medications for long-term use of weight loss.



Xenical, however, is not exempt from side effects and restrictions. First, when taking Xenical, a person should reduce the number of fats in the diet to less than 30% of their daily food intake. If the person consumes more than 30% of their daily fat intake, they may have some side effects, such as a greater amount of stool, urgent stool, increased flatulence, and oily stool, as well as grease stains on clothing.



Xenical should not be taken by people who have diabetes that requires medication, as well as those who are taking blood thinners such as Coumadin, anyone who has received an organ transplant in the past, or who is currently taking cyclosporine. People who have problems or problems digesting and absorbing nutrients from food should undergo a careful examination before taking this medication. Since this medication inhibits the absorption of nutrients, the person must also take multiple vitamins, but not within 2 hours after taking Xenical.



Keep in mind that these medications are not for anyone who wants to lose weight. They are designed for people who are remarkably obese and who have tried other weight loss methods in the past but have not been successful. The person who is considering taking medications such as these should be under the care of a medical professional and receive continuous attention and observation to avoid any serious problems with these medications.
