A list of antidepressants. These are mood altering medications utilized to fight depression as well as other illnesses, including fibromyalgia. From 1995 to 2006, the use of Antidepressants doubled within the United States. That said, it has also been suggested that 25% of Americans on mood altering drugs were over-diagnosed. Nonetheless, these drugs should only be taken with a doctor's supervision. When it comes to one's health, one should note that antidepressants have recently been shown to suffer from the placebo effect in which placebos work just as well as the actual medication. Coupled with the over-diagnosis mentioned earlier, this makes sense. The placebo effect is also in no way exclusive to only the antidepressant market.
