o Dose: 10 mg tablet twice a day
o How it works: Belviq activates hunger control mechanism in the brain
o The research: Researchers tested Belviq in three large clinical studies from 1 to 2 years with a total of 8,000 overweight and obese participants. Almost half (47%) of the people in the studies lost at least 5% of their total body weight after 12 weeks. The participants taking Belviq lost 3 to 3.7% more of their body weight than the participants on the placebo.
- The research: Researchers tested Qsymia in two large clinical studies that included almost 3,700 overweight and obese participants. On the lowest dose, the participants lost 6.7% more weight than the participants on the placebo . On the recommended dose (the middle dose), participants lost an average of 8.9% more than those on the placebo. Sixty-two percent of the participants on the lowest dose and 70 percent of the participants in the recommended dose groups lost at least 5% of their total body weight compared to 20% of the participants in the placebo group.
