Antidepressants are the medications most often prescribed to treat clinical depression. Depression is caused by an imbalance in the brain’s chemicals. Dopamine, serotonin, and norepinephrine effect a person’s emotional response affecting mood. These medications are effective by balancing the brain’s natural chemicals. Antidepressants help control these chemicals and bring them back into balance.

Among the different antidepressants, Selective Serotonin Reuptake Inhibitors (SSRIs) are the most commonly prescribed medications. Examples include:

Citalopram (Celexa)
Fluoxetine (Prozac)
Sertraline (Zoloft)
Paroxetine (Paxil)
Escitalopram (Lexapro)
Other common antidepressants are Serotonin and Norepinephrine Reuptake Inhibitors (SNRIs). These medications include duloxetine and venlafaxine. These medications work in a similar way to SSRIs. Both SNRIs and SSRIs are newer classes of antidepressants. They are more often prescribed because of their few side effects.

However, older medications are sometimes the best solution despite their many side effects and interactions. These older classification of antidepressants include:

Monoanamine Oxidase Inhibitors (MAOIs)
Bupropion works on dopamine receptors. Unlike other medications, this drug does not fit into the specific SSRI and SNRI grouping.

For adults, antidepressants are safe with few side effects. However, recent studies indicate they may not be safe for children and teens. According to research, 4% of the nearly 4400 participants involved either thought about or attempted suicide. Only 2% of the participants who were receiving sugar pills instead of the antidepressants had similar thoughts or actions.

The FDA does have a warning on antidepressants that are used to treat children and young adults stating that there may be an increased risk of suicidal thinking or attempts. The FDA urges anyone who has increased thoughts of suicide to speak with their physician immediately.

The warning also affects patients of all ages during the first few weeks of treatment. The FDA suggests that family members or caretakers should monitor patients for increased suicidal thinking or behavior or other changes in behavior such as withdrawal from normal situations, agitation, and sleeplessness. As usual, caretakers should report any significant changes to the doctor.
