Belviq Review - Does This Diet Drug Really Work? Are side effects and negative user reviews deal breakers?

Editor's Review: 3.5 / 5.0

belviqbottleandpillscropIf you haven’t looked closely at Belviq, here’s your chance. We did one of our comprehensive reviews, examining the side effects, ingredients, clinical studies and overall customer care. Plus we scrutinized hundreds of dieter responses, which we found online. At this point we summarized the information we found to give you the bottom line.

EDITOR'S TIP: Substitute Belviq with a proven fat burner such as Leptigen for better results.

What You Need To Know

First off, Belviq is a prescription weight-loss drug. It was approved by the FDA and must be obtained through a licensed physician. This pill is only suitable for individuals who’re considered obese or have a BMI (body mass index) of 30 or greater. The purpose of Belviq is to send a signal to the brain, telling it you are full and satisfied. This way you eat fewer calories. The ingredient used is loraserin hydrochloride. A healthy diet and exercise plan are mandatory while taking Belviq. As for the proper dosage, your doctor will decide what prescription is right for you. It may also assist with improving blood pressure, cholesterol and blood sugar levels.

Belviq was first approved for weight-loss in 2012. This drug was developed by Arena Pharmaceuticals and it can be used by both women and men. Pill use is regulated by licensed doctors and there is an official website that provides plenty of information on Belviq, but read on…

Serious Side Effects – “Be Cautious?”

The first thing dieters should take into consideration with this one is the potential for Belviq side effects. According to our Research Editor, “Belviq can lead to all sorts of reactions. These include low blood sugar levels, constipation, fatigue, nausea, slow heartbeat, back pain, dry mouth, drowsiness, bladder pain, cold sweats, bloody urine, chills, depression, cough, headache and fast heartbeat.”

One dieter stated, “Serious headaches and bloating.”

Another user said, “I just cannot deal with the headaches, which is why I will have to stop taking them.”

Negative User Reviews – “What’s Up?”

There are quite a few discouraging dieter reviews posted online for Belviq. In fact, one user said, “The first week I had horrible headaches but the cravings were still there. After the first 30 days, I called my doc about feeling bloated. She prescribed me a water pill. Meanwhile, I had NO weight-loss on Belviq after the 30 days.”

“It didn’t help me at all. I craved chocolate all the time. Not worth the 75.00 a month,” commented another dieter.

Our research has proven that if there is a specific part of a weight-loss program or diet pill that is quite burdensome (too many side effects, negative customer reviews, high cost) the chances of lasting results are slim. So, if Belviq does lead to a lot of reactions, this could be problematic.

The Science – “Clinical Evidence?”

There have been some clinical studies done with Belviq. These have shown that this diet pill can help with satiety. The initial report involved 8,000 different participants. However, Belviq does not work for everyone and some people are not eligible to use this weight-loss drug. We at DietSpotlight like to see solid research that supports the product before we recommend it.

The Bottom Line – Does Belviq Work?

Should we be on the run to be first in line for this one? First off, we appreciate that Belviq is approved by the FDA to assist with weight-loss in obese individuals. However, there are clearly a lot of adverse effects that go along with this diet pill. Also, you are not even eligible for Belviq unless you have a BMI of 30 or greater. Not to mention, this drug is quite costly and there is some talk of lawsuits (online).

If you want to lose more weight and get fit now, we recommend you go with a diet product that is backed by real clinical studies, is available to all adults, but does not cause harsh side effects.

Among the best products we’ve seen in 2015 is one called Leptigen. This supplement contains a blend of four unique ingredients that are proven in published clinical studies to help increase fat loss and elevate metabolism. We have not located any discussion of adverse effects and customer comments posted online reveal people are seeing significant results.

Also, the makers of Leptigen are so confident in their product they’re offering a Special Trial Offer, which is a good sign.

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.

List of Ingredients

  • 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. Advantages
  • 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.

    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.
