Medicine and psychotherapy are usually used in the treatment of MDD. The right lifestyle changes can also reduce the certain symptoms.

Patients with severe MDD or those who are going to commit suicide may need hospitalization during treatment. Many people will have to participate in outpatient treatment programs until their symptoms resolve.

Medications

MDD is often treated with antidepressant medications prescribed by primary care providers.

Selective Serotonin Reuptake Inhibitors (SSRIs)

SSRIs are commonly prescribed antidepressants by doctors. SSRIs inhibitors protect against brain breakdown by making serotonin levels higher.

It’s believed that serotonin is responsible for mood, as it’s one of brain’s neurotransmitters. This supplement could lead to healthier sleeping patterns and improve mood.

MDD patients believed to have low serotonin levels. The dose of serotonin in the brain can be increased by an SSRI to help relieve MDD symptoms.

Fluoxetine (Prozac) and citalopram (Celexa) are well-known SSRIs. There are relatively few side effects with these medications, and most people tolerate them well.

Another type of antidepressant commonly prescribed, along with SSRIs, is SNRIs, which inhibit serotonin norepinephrine reuptake. These affect norepinephrine and serotonin.
