Mechanism of Action
Sibutramine works by acting on certain areas of the brain to decrease a person’s appetite. It is believed to work by blocking or decreasing serotonin and norepinephrine reuptake from the brain. This leads to increased levels of these neurotransmitters in the brain, increasing the feeling of fullness, which in turn reduces a person's overall appetite.
How Long Does It Take to Work?
Sibutramine usually begins to work within 1-3 weeks, although it may take longer in some people. Results may vary based on a person’s individual metabolism and health condition.

Sibutramine is absorbed rapidly in the gastrointestinal tract, reaching peak levels within 1 to 4 hours after administration. The active form of sibutramine is N-desmethylsibutramine, which is also absorbed rapidly.
