If you haven’t looked closely at Belviq, here’s your chance. We payed close attention to side effects, ingredients, clinical studies and overall customer care. Furthermore, we scrutinized hundreds of dieter reviews and testimonials. Then, we summarized and refined to give you the info you need.

What You Need To Know About Belviq

First off, Belviq ingredients are loraserin hydrochloride, silicified microcrystalline cellulose, hydroxypropyl cellulose,  croscarmellose sodium, colloidal silicon dioxide, polyvinyl alcohol, polyethylene glycol, titanium dioxide, talc  and magnesium stearate. [1] The medication promotes weight-loss by causing satiety. It may also improve blood pressure, cholesterol and blood sugar levels. [2]

Belviq was first approved for weight-loss by the FDA in 2012. This drug was developed by Arena Pharmaceuticals and it can be used by both women and men. You can only purchase the medication at a pharmacy, with a prescription from a licensed physician. We like that healthy eating and exercise are promoted, but read on…

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.” [3]

One dieter stated, “Serious headaches and bloating.” [4]

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.” [5]

“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 Behind Belviq – “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 this year is one called Dietspotlight Burn. 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 Dietspotlight Burn are so confident in their product they’re offering a special trial offer, which is a good sign.

Previous Belviq Review (Updated January 14, 2014):

What You Should Know About Belviq

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 in Belviq

  • Loraserin Hydrochloride

Product Features of Belviq

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.

Belviq Conclusion

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.

Belviq Side Effects:

Any weight-loss supplement that has a high number of negative reviews should raise a red flag. Belviq purports to be a safe supplement, but many users report negative side effects. Keep these side effects in mind and be cautious when making a purchase decision.


A bad headache can make it really hard to get through the day. You feel immense pressure in your head. This in turn makes you feel weak and light-headed. You may even begin sweating.

What causes headaches?

Everyday headaches are caused by not drinking enough water, being out in the sun too long, and not getting enough sleep. A number of illnesses cause headaches. These include glaucoma, concussion, and stroke. [1]

Dry Mouth

Dry mouth is when you don’t have enough saliva in your mouth. Your mouth becomes sticky and dry. People with dry mouth tend to get chapped lips and bad breath. You may also have a hard time chewing.

What causes dry mouth?

Dry mouth is usually the result of dehydration. To avoid getting dry mouth, make sure to drink plenty of fluids—especially if you’re going to be out in the heat. Many medications cause dry mouth, especially those used to treat inflammation, depression, and high blood pressure.


Also known as bounding pulse, this is a condition in which your heart beats harder than it should. Often, you can feel your heart skipping beats or going too fast.

What causes palpitations?

When accompanied by shortness of breath or chest pain, palpitations can be a sign of abnormal heart rhythm, hyperthyroidism, or tachycardia. [2]


When you’re nauseous, you have the urge to vomit. You have no appetite (just the sight of food makes you sick). Stomach pain, bloating and sweating often accompany nausea. You may also feel your abdomen contract mildly as it attempts to empty its contents.

What causes nausea?

Food poisoning, stomach bacteria, and ulcers are all known to cause nausea.


Constipation is painful and uncomfortable. You’re unable to pass stool, even when you have the urge to do so. As a result, you have stomach pain and bloating. When you are able to defecate, your stool is hard and dry.

What causes constipation?

Constipation, irritable bowel syndrome, and hypothyroidism are the most common causes of constipation. You may also need to eat more fiber, drink more water, and do more exercise. Belviq has too many side effects to be considered a safe supplement. For a clearer understanding of how it might affect your body, talk with your doctor.

  appeal to me

I’m a 67yr, male I just saw the most creditable commercial on T.V. You showed real people in it not he stick models, that need to go and find something to eat. Do not change it, if it appealed to me as male I’m sure it appealed to female viewers.

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

Maribel (Editor)

Hello Armando. All users are different, some people see the effects right away and others see results in a week or two.


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.


Did not work for me, I was on it for one month, lost 5 lbs doc took me off????

John R.

More important than exercise, is food intake. Food is 70% of any successful weight loss programs, I have lost 43lbs taking belviq, but I quit sodas, and cut most sugars out, the only sweets I eat are fruit, occasionally I will cheat and get a cookie. The only thing I drink is water and vegetable or fruit infused water. I eat a lot of chicken, salmon, and green vegetables. For instance mt breakfast this morning was two eggs with an avocado fried on the side. Belviq by itself will not do the trick, more than a few lbs anyway.


did you incorporate exercise in your weight loss and if so how often


Is it safe to take Lexapro 20mg we with Belviq

Maribel (Editor)

Hi Maria! Because of possible interactions with medications, please make sure to consult with your physician before taking this product.


Yes I just started yesterday and my dr said its safe!!


I have been taking Belviq for about 2 months. I really haven’t lost or gained any weight. I have 65 more ponds to lose. I am so tired all of the time. I was wandering if it was ok to take a fat burner with this.

John R.

I have had great success with Belviq, I started working out and eating healthy. Taking Belviq alone I do not think will get anybody to their weight loss goals.

Victoria (Editor)

Hi! Because of possible interactions, please make sure to consult with your physician before taking this product.

  I guess it works for som
Tanisha (Verified User)

I have been taking belviq for 3 days using the 15 days of free pills and so far I am still feeling very hungry even after I have eaten something substantial. I am SOOOOO tired like I am dragging myself around, which makes it hard to get into my workout routine. I want to sleep a lot. I felt very full on the first day and had to force myself to eat, but not on day 2 or 3. This pill is nothing like Phentermine, which gives you that boost of energy and puts you in a state of euphoria while suppressing your appetite strongly from day 1. So far I am disappointed with this med. I guess it works for some and not for others. I weigh 204 and I am trying to reach my goal of 170 so if this doesn’t work after the next several weeks I will ask for a different prescription.

  Just started using this
christine (Verified User)

i just started belviq today. im soooo scared reading all these bad reviews. ugh. im 320 lbs and need to lose 170.ugh

John R.

Hang in there, for me it definitely worked, I have dropped from 260 to 217 a little over 4 months. I feel better , more energy. But don’t just rely on Belviq alone, you have to get active, and diet change.

Your GeeName

Christine and others I use belviq and IT DOES WORK. I go to Dr who prescribed it and no problems in the beginning I was hesitated also. I lost 10 pounds mostly because I had no appetite. Oh I am 53 and need to lose 20…10 down….10 more to go.GREAT PRODUCTS ?


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 am looking for.

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.


I am 67yrs. and am 292lbs. I need to lose around 140 lbs. is belviq ok for me and how long will it take ? other than being overweight, I have no bloodpressure probs, no heart probs as my dr. would say ” theres nothing wrong with you , you”re just fat, LOSE IT !”

John R.

Hi, I am 51 weighed 260 when I started in Aug, I am now down to 217 so a little over 4 months , but I started working out and cut out sugar (all soda’s gone) and cut bread products way down.
