Does prozac cause weight gain or slow the metabolism?

"Metabolic
Very common (10% or more of users): Anorexia (up to 17%)
Common (1% to 10% of users): Decreased appetite, increased appetite, weight loss"
Weight gain caused by increased appetite can be controlled by simply eating sensibly. But psychotropic medications can cause metabolic changes and changes to fat storage mechanisms in a very small percentage of people and this weight cannot be modified by life style changes such as diet and exercise.

It makes you hungry and eat more... Did you gain weight from it??

It can cause weight gain; however, some lose weight. When I took prozac I didn't gain or lose. Your dancing should help if you have any problems with weight. Also eat a healthy diet with plenty of veggies, fruit, and lean protein and drink plenty of water and real fruit juice with no added sugar. Careful with fruits also as they are high in sugar.

Your best remedy is an acute calorie intake, this med may help modify your behavior, but it will be unlikely to will add anything but water weight, if even that.
