Is it safe to take celexa (citalopram) and phentermine at the same time?

Thanks for asking!: Phentermine is a stimulant used as a weight loss supplement. There are no known drug interactions with celexa, (citalopram) an ssri antidepressant; however, it would be better to find safer, healthier ways to lose weight including eating less portions of fats & starches, consuming more fruits and veggies and engaging in regular exercise.
