Of course. Safety is more important than anything, more so than effectiveness, in treatment. We prescribe drugs approved by the U.S. FDA as obesity treatments. Medical doctors consult patients during every visit to monitor the effectiveness and side effects of the drugs. Even after the treatment is completed, we gradually reduce the dosage according to a schedule to ensure that excessive appetite does not return. In very rare cases, discomfort and other symptoms appear during the treatment process, but FDA-approved drugs whose pharmacokinetic mechanisms have been clearly revealed are expelled out of the body after going through the metabolic process. As such, most side effects are temporary.
