More than 1 in 10 Americans take antidepressants to treat depression. For the most part, these medications get the job done. Your health care provider may need to tweak your dosage or switch you to a different kind to find the best fit, but most people notice an improvement in 6 weeks or so.
Like every other medication, antidepressants have side effects that affect some, but not all people. One of the most notable is weight gain.

No. And it doesn’t happen to everyone.
“In general, weight gain is a possible side effect of most antidepressants, such as Zoloft, Prozac or Celexa, but each person will react to antidepressants differently,” Naidoo says.
How much weight gain is typical? A quarter of those who take antidepressants gain 10 pounds or more, Naidoo estimates. Is Weight Gain More Likely With Some Types of Antidepressants Than Others?
Yes. Antidepressants are grouped based on how they interact with certain chemical receptors in your brain. The mo
