Having a hard time losing weight? Your brain may play a role.

Your brain has many jobs. One is to ensure that you never go hungry. Unfortunately, when we diet and reduce what we eat, the body may believe we are starving. It then sends signals to the brain to eat more.

Lorcaserin, the active ingredient in BELVIQ/BELVIQ XR helps you feel full by targeting a hunger receptor in the brain. The precise way BELVIQ/BELVIQ XR produces feelings of satisfaction is not fully understood. By adding BELVIQ/BELVIQ XR to your weight-loss routine, you may be able to eat less and still feel satisfied.


It all starts with chemical messengers called neurotransmitters. Some neurotransmitters, like dopamine, can stimulate the brain, telling us to take a certain action such as "Eat now!”

Other neurotransmitters, like serotonin, can make you feel full. Basically, when we smell food, some neurotransmitters are released that make us want to eat. When we eat, serotonin is released, making us feel full.

Just as serotonin naturally turns on receptors to cause feelings of fullness, BELVIQ/BELVIQ XR is believed to selectively turn on these “fullness receptors,” helping you feel full while eating less food.

BELVIQ/BELVIQ XR is not a stimulant or narcotic. It is a federally controlled substance with some risk of abuse or dependency.
