New diet pill no easy path to weight loss

Experts are skeptical that Belviq, the first weight-loss treatment approved by the FDA in more than a decade, is worth the bother.

Arena Pharmaceuticals' (ARNA) Belviq, the first diet pill approved by the FDA in more than a decade, is finally available to patients Friday -- but some experts are advising people not to bother.

For one thing, Belviq has a host of side effects ranging from dizziness to heart valve problems to painful erections. To make matters worse, patients have to take Belviq for the rest of their lives and it carries a hefty wholesale price of $200 per month. The results achieved by Belviq, which the FDA has approved for adults who are overweight and also suffer from diabetes or other serious medical conditions, are nothing special either. 
"In a study, the average weight loss over the course of a year using Belviq was 3.7% more of a person’s total body weight than the patients on placebo," according to The Los Angeles Times, adding that's a loss of fewer than 10 pounds for a 250-pound person. "That sort of loss could be easily achieved by mild changes in eating and exercise habits."Image: Person on scale (© Purestock/SuperStock)
Consumer Reports, which is advising people to take a pass on Belviq, said patients in one trial lost up to 5% of their body weight after 12 months but regained 25% of it by the end of the second year.

For its part, Arena said Belviq has been proven to be safe and effective.

The costs associated with obesity are astounding, some $190 billion a year, or more than 20% of U.S. health care expenditures.

Unfortunately, for many there are no shortcuts to losing weight.

This author needs to go back and read the specs from the FDA label, Jonathon Berr is 100% inaccurate on this piece.  Also, he needs to read what the American Association of Clinical Endocrinology endorsement says about new "novel" weight lose medication options. 


Oh, did I mention that Belviq is a new "Novel" Rx.  The first new "Novel" Obesity Rx approved in 13 years, with "No' REMS.

"For its part, Arena said Belviq has been proven to be safe and effective."

what an ignorant statement. The FDA determined Belviq to be safe and effective.

Another author who doesn't know what he's talking about. Either ignorant, uninformed, or yet another shill for hedge funds who are short ARNA and are looking at a billion dollar loss as Arena blows wall street expectations out of the water with stellar performance.

8% completer efficacy / 12% responder efficacy in  a year - excellent safety profile. Poor short sellers. No article is going to help them.

[BRIEFING.COM] The stock market is doing pretty much what it was expected to do today in front of the FOMC decision (i.e. nothing).  The major indices are little changed as traders wait anxiously for the Fed's latest directive and updated economic projections.

Everyone is waiting to see if the "considerable time" language is maintained in the directive after Wall Street Journal Fed watcher, Jon Hilsenrath, suggested yesterday it could be.

Mr. Hilsenrath's article ... More
