Prescription Diet Pills

Prescription Diet Pills are diet pills that have been FDA approved and supposedly are the most powerful diet pills available on the market. There is a catch, you need to get a prescription before you can use it. Aside from the difficulty of obtaining the needed prescription, the price tag is usually pretty high.

Another difficulty inherent with prescription diet pills is that there are hundreds of non-prescription look-alike diet pill that attempts to capitalize on popular prescription diet pills. Below, there is a list of the three most popular prescription diet pills.

Phentermine

Phentermine is an FDA approved appetite suppressant that reduces weight in obese patients. It is prescribed for individuals who are at increased medical risk because of their weight and works by helping to release certain chemicals in the brain that control appetite.

Phentermine, like other prescription drugs, works to alter transmitters sent by the brain. It is a centrally-acting stimulant that stimulates signals sent by the brain. These neurotransmitters either give a green light or a red light to hunger. As a result, it causes your appetite to be suppressed because the brain does not receive the hunger message.

Phentermine is a powerful appetite suppressant, however it should be only be used under the careful supervision of a trained physician. Phentermine is a powerful appetite suppressant, but it does have its fair share of side effects.

Xenical (Orlistat)

Available now in the prescription free version called Alli, Xenical is a powerful fat blocking supplement. Xenical works to prevent the absorption of fats during digestion. This in turn will help reduce calories that you intake.

Xenical is a derivative of listatin- a inhibitor of pancreatic lipases. It helps release the chemicals that absorb the fat created during digestion.

However, Xenical is also highly controversial because of its side effects.

• Gas with an oily anal discharge
• Loose stools or diarrhea
• More frequent bowel movements
• Hard-to-control bowel movements

Many users have claimed minimal weight loss, yet have caused such embarrassing side effects.

Acomplia

Acomplia is a possibly dangerous prescription diet pill that isn’t even available within the US. The reason for this exclusion is the fact that the FDA has banned it only ingredient the drug Rimonabant. There are serious questions posed about possible negative long term side-effects. Acomplia is the first in a new class of therapeutic agents called Receptor Blockers. Acomplia is used to treat obesity and help reduce weight loss. Acomplia acts by selectively blocking receptors found in the brain and in peripheral organs important in glucose and fat metabolism. Acomplia switches off the same brain signals that make people hungry when they smoke cannabis.

In clinical trials, Acomplia has been shown to promote sustained weight loss. Approximately half of the subjects showed weight loss beyond their expected goals.

Side effects that have been shown from taking Acomplia were vomiting and nausea.
