Randomized Controlled Trial Multicenter Study
Fluoxetine: a randomized clinical trial in the maintenance of weight loss.
Because current weight-reduction treatments have considerable recidivism, a therapy that could help patients maintain weight loss would be of benefit. A six-center, randomized, double-blind trial compared the effects of the specific serotonin uptake inhibitor, fluoxetine hydrochloride, and placebo on maintenance of weight loss. Obese outpatients who had lost > or = 3.6 kg after 8 weeks of single-blind fluoxetine 60 mg/day in the qualification phase (N=317 [70.4% of patients entered]; mean +/- standard deviation [SD] weight loss, 6.8 +/- 2.8 kg) were randomly assigned to fluoxetine 20 mg/day (N=104), fluoxetine 60 mg/day (N=106), or placebo (N=107) for 40 weeks (maintenance phase). ⋯ Few patients discontinued for any single adverse event. Fluoxetine 60 mg/day was effective for a longer period than fluoxetine 20 mg/day or placebo in maintaining weight loss. Overall, fluoxetine was safe and well tolerated.
