<unk> s are medications used to treat major depressive disorder, some anxiety disorders, some chronic pain conditions, and to help manage some<unk> dictions. Common side-effects of<unk> s include dry mouth, weight gain, dizziness, headaches, sexual dysfunction, and emotional blunting. There is a slight increased risk of suicidal thinking and behavior when taken by children,<unk> olescents, and young<unk> ults. A discontinuation syndrome can occur after stopping any<unk>  which resembles recurrent depression. Some reviews of<unk> s for depression in<unk> ults find benefit while others do not. Evidence of benefit in children and<unk> olescents is unclear. The twenty-one most commonly prescribed<unk>  medications were found to be more effective than placebo for<unk> ults with major depressive disorder in a 2016 meta-study. There is debate in the medical community about how much of the observed effects of<unk> s can be attributed to the placebo effect, with some claiming that there is no effect above and beyond it. Most research on whether<unk>  drugs work is done on people with very severe symptoms, a population who exhibits much weaker placebo responses, so the results cannot be extrapolated to the general population. There are effective treatments for depression which do not involve medications or may be used in conjunction with medications.
