Potential Risks and Concerns of Weight
Loss Drugs
As far as the risks of weight loss drugs
are concerned, long-term weight-loss medication treatment for obesity
raises the following issues.
Potential for Abuse or Dependence of
Drugs
Currently, all prescription medications to treat obesity except orlistat
are controlled substances, meaning doctors need to follow certain restrictions
when prescribing many weight-loss medications. Although abuse and dependence
are not common with non-amphetamine appetite-suppressant medications,
doctors should be cautious when they prescribe these medications for patients
with a history of alcohol or other drug abuse.
Development of Drug Tolerance
Most studies of weight-loss medications show that a patient's weight tends
to level off after 4 to 6 months while still on medication. While some
patients and physicians may be concerned that this shows tolerance to
the medications, the leveling off may mean that the medication has reached
its limit of effectiveness. Based on the currently available studies,
it is not clear if weight gain with continuing treatment is due to drug
tolerance.

Note About Weight Loss Pills
To reduce health risks, do not buy weight loss pills or supplements
without first consulting your doctor. And when taking weight loss
drugs or pills, be sure to check in with your doctor regularly.
