Treatment options

- MEDICATIONS FOR DEPRESSION:
- Drugs used to treat depression are called antidepressants.
- Common types of antidepressants include:
- Selective serotonin re-uptake inhibitors (SSRIs), including fluoxetine (Prozac), sertraline (Zoloft), paroxetine (Paxil), fluvoxamine (Luvox), citalopram (Celexa), and escitalopram (Lexapro).
- Serotonin norepinephrine reuptake inhibitors (SNRIs), including desvenlafaxine (Pristiq), venlafaxine (Effexor), and duloxetine (Cymbalta).

- If you do not feel better with antidepressants and talk therapy, you may have treatment-resistant depression. Your doctor will often prescribe higher (but still safe) doses of an antidepressant, or a combination of medications. Lithium and thyroid hormone supplements also may be added to help the antidepressants work better.

Your doctor may recommend changing your dose or switching to an alternative drug. Never stop taking your medications without first talking to your doctor.
