Serzone (nefazodone) is used to treat depression. It may reduce symptoms of depression, including feelings of guilt, sadness, or worthlessness, tiredness, loss of interest in daily activities, fluctuations in appetite, sleeping too much / insomnia, or thoughts of suicide. Nefazodone is usually used after other treatments have not worked, due to risk of liver disease while on this medication.

It works by helping change certain chemicals in the brain, including serotonin and norepinephrine, which professionals refer to as “neurotransmitters.” It is not yet well-understood why changing these neurochemicals results in symptom relief for the conditions this drug is commonly prescribed for.
