Meridia Uses

How Does Meridia Work?

Meridia works by helping you to feel full more quickly. It acts in the brain, where it increases the levels of certain brain chemicals (including serotonin, norepinephrine, and dopamine) in specific areas of the brain.
Meridia does not increase the production of brain chemicals. Instead, it prevents the "reuptake" of the chemicals. As a message travels down a nerve, it causes the end of the cell to release a brain chemical. The chemical enters the gap between the first nerve cell and the one next to it. When enough of the chemical reaches the second nerve cell, it activates receptors on the cell, and the message continues on its way. The first cell then quickly absorbs any of the extra chemical that remains in the gap between the cells, preventing the chemical from further activating the second cell. This is called "reuptake."
Meridia helps to block the reuptake of serotonin, norepinephrine, and dopamine, so more of these chemicals remain in the space between the brain's nerve cells. This gives the chemicals a better chance of activating the receptors on the next nerve cell. This action promotes a sense of fullness (the signal to stop eating). It does not suppress the appetite (the signal to start eating).

Meridia Use in Children

Meridia is not approved for treating obesity in children under the age of 16 years old. Talk to your child's healthcare provider about the benefits and risks of using Meridia in children. There is some concern that Meridia may increase the risk of suicidal thoughts in children, much like SSRI antidepressants, which work in a similar way as Meridia.

Off-Label Meridia Uses

On occasion, your healthcare provider may recommend Meridia for something other than weight loss. This is called an "off-label" use. At this time, there are no universally accepted off-label Meridia uses.
