Obesity

The effect of Fluoxetine on lipid profiles in overweight or obese Individuals: A systematic review and meta-analysis of randomized controlled trials

Diabetes Res Clin PractPublished Systematic review and meta-analysis of randomised trials

Authors' conclusion

Fluoxetine significantly lowers TG and raises HDL-C in overweight or obese individuals. The effect on TG is more pronounced at 60 mg/day and in shorter interventions. Further research is needed to evaluate long-term impacts.
