Belviq is a prescription weight loss drug approved for human use by the Food and Drug Administration (FDA) in 2012. The drug was first denied approval by the FDA because animal studies showed a risk of tumors developing with use, but Arena Pharmaceuticals, the company behind Belviq, was not willing to allow the time and money behind the development and testing of Belviq to go to waste. They resubmitted an application to the FDA with more information on the studies and the FDA granted approval.

Belviq is only available from a physician with a prescription. The medication is designed for dieters with a BMI of 30 or more though dieters with a BMI of 27 or lower will be prescribed the drug if there are secondary medical conditions that may be or are being exacerbated by the extra weight. There are negative side effects associated with Belviq that should be taken into consideration before starting the weight loss drug.

  • Loraserin Hydrochloride

Product Features

The weight loss market is riddled with dangerous prescription drugs that were supposed to help dieters lose weight. Fen-phen is probably one of the most infamous of all. Dieters lost weight, but some also faced horrible side effects like damage to heart valves. According to Arena Pharmaceuticals, this type of side effect is not an issue with Belviq, but dieters may not be quick to ask for then drug due to the already sketchy history of the medication. The FDA denied the first application because of reported tumors associated with use. Belviq resubmitted and the drug was approved.

Belviq works by activating a full sensor in the brain. Essentially the drug tells the brain to tell the stomach – I’m full. That keeps the dieter from overeating and thus promotes weight loss. There are a few problems with the drug, however. First, if a dieter has not lost at least 5% of body weight by the 12th week of use, the drug must be discontinued because the dieter will not likely use weight taking Belviq. Then there are the possible side effects of taking the Belviq weight loss drug. Possible side effects include fatigue, migraine headaches, memory loss, constipation and nausea. If you have diabetes the drug may affect your blood glucose levels.

Long-term studies show weight loss of no more than 4% on average after one year of use. That adds up to 16 pounds for a 400-pound dieter or 8 pounds for a 200-pound dieter. The studies included reduced calorie diet and exercise counseling during the trial.


  • May suppress hunger.


  • May cause negative side effects.
  • The initial study included only 8,000 participants.
  • The drug may cause tumors in animals.


Prescription weight loss drugs don’t have a great past history in the US. This drug is not associated with huge weight loss numbers; even when dieters were given information on how to lose weight with exercise and diet. We’d suggest dieters wait until further testing is completed before choosing this drug. The FDA has ordered a heart study in the near future after the drug is released in 2013.

    This worked great at first, but now after having been on it for about 3 months, it no longer seems to be effective. I have lost 13 pounds in as many weeks just like my Doctor told me I would.

    I have been taking Belviq for only 1 week. I thought that I would at least start feeling a slight appetite loss BUT nothing. I have no side effects but once again I think that it will not work either…I will incorporate working out next week in hopes that I get the results that I am looking for.

    How long does/should it take for Belviq to take effect?



    You can feel your cravings for food go away within a few hours. Belviq works very fast



    This drug works extremely well with low side effects. I have lost 27 pounds in 45 days (started at 230). It reduces the cravings for sugar dramatically. I have been overweight my entire life and tried other drugs, Belviq is an excellent medication.
