The Claim
The long-term safety of the weight loss drugs lorcaserin, phentermine/topiramate, and naltrexone-bupropion has not been sufficiently established and remains largely unknown.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
We don’t really know if these weight loss pills are safe to take for years and years—scientists haven’t figured it out yet.

What the research says
1 studyStudy: Reducing the Risk of Obesity: Defining the Role of Weight Loss Drugs
