Medication

For some people, antidepressant medications may help reduce or control symptoms. Antidepressants often take 2-4 weeks to begin having an effect and up to 12 weeks to reach full effect. Most people will have to try various doses or medications to find what works for them.
​Selective serotonin reuptake inhibitors (SSRIs) act on serotonin, a brain chemical. They are the most common medications prescribed for depression.
​​Serotonin and norepinephrine reuptake inhibitors (SNRIs) are the second most common antidepressants. These medications increase serotonin and norepinephrine.
​Norepinephrine-dopamine reuptake inhibitors (NDRIs) increase dopamine and norepinephrine. Bupropion (Wellbutrin) is a popular NDRI medication, which causes fewer (and different) side effects than other antidepressants. For some people, bupropion causes anxiety symptoms, but for others it is an effective treatment for anxiety.
Mirtazapine (Remeron) targets specific serotonin and norepinephrine receptors in the brain, thus indirectly increasing the activity of several brain circuits. Mirtazapine is used less often than newer antidepressants (SSRIs, SNRIs and bupropion) because it is associated with more weight gain, sedation and sleepiness. However, it appears to be less likely to result in insomnia, sexual side effects and nausea than the SSRIs and SNRIs.
​Second-generation antipsychotics (SGAs), or “atypical antipsychotics,” treat schizophrenia, acute mania, bipolar disorder and bipolar mania and other mental illnesses. SGAs can be used for treatment-resistant depression.
​Tricyclic antidepressants (TCAs) are older medications, seldom used today as initial treatment for depression. They work similarly to SNRIs but have more side effects. They are sometimes used when other antidepressants have not worked. TCAs may also ease chronic pain.
  • Amitriptyline (Elavil)
  • Desipramine (Norpramin)
  • Doxepin (Sinequan)
  • Imipramine (Tofranil)
  • Nortriptyline (Pamelor, Avantyl)
  • Protriptyline (Vivactil)
Monoamine oxidase inhibitors (MAOIs) are less used today because newer, more effective medications with fewer side effects have been found. These medications can never be used in combination with SSRIs. MAOIs can sometimes be effective for people who do not respond to other medications.
