Orlistat is the only currently available anti-obesity drug for long-term management due to its favorable cardiovascular safety profile compared to withdrawn agents like sibutramine and rimonabant.

Orlistat is the only long-term anti-obesity drug currently available because it does not carry the cardiovascular risks of older drugs. It works by blocking fat absorption. You must take 120mg with meals. Expect gastrointestinal side effects if you eat fat; managing your fat intake can reduce these side effects. It provides modest weight loss (~3kg over a year) but improves metabolic markers.

GoodSupportsHIGH confidence
Even if orlistat is not as effective as other drugs in reducing body weight, orlistat is presently the only available choice for the treatment of obesity because of its safety for cardiovascular events and positive effects on diabetic control.
