Fluoxetine and weight gain

I am on fluoxetine for my depression and have gained weight.  Can I take phentermine to lose weight?

I think you should be careful as there is chance of interaction.  Many antidepressants can interact with phentermine and increase the risk for seizures. I would recommend xenical instead of phentermine. However, do not take the fluoxetine at the same time as xenical, as it won't be absorbed. Best advice- walk more and eat less. Stop relying on medications for weight loss.
