I just saw an ad for the weight loss pill Belviq, (lorcaserin) is it safe and effective to use? Thank you

Don't believe the. hype! Ads are intended to sell, and to entice, and not necessarily to provide results or outcomes to everyone. You have to look behind the hype & find out the ingredients & see whether they are even safe to use. Your best bet to losing weight is to work with your doctor to come up with a medically sound plan that involves exercise & good nutrition (work with a nutritional consultant), not a pill.
