Over the past 15 years, other obesity drugs have seen their usage ramp up far faster than Belviq has since it hit pharmacy shelves on June 11. More than that, a look at prescription trends for older medicines reveals the risk that a weight-loss drug can initially seem to take off, but then see its usage peak early and decline as patients become dissatisfied with its safety or efficacy. If Belviq could be used as much as these older medicines were at their peak, it might become a $1 billion seller.

It reduces the incidence of diabetes type II in people who are obese around the same amount that lifestyle changes do. Benefits aside, however, orlistat is notorious for its gastrointestinal side effects (sometimes referred to as treatment effects), which can include steatorrhea (oily, loose stools).
