Phenelzine is a monoamine oxidase inhibitor (MAOI) that works by increasing the levels
of certain chemicals in the brain.
Phenelzine is used to treat symptoms of depression that may include feelings of sadness,
fear, anxiety, or worry about physical health (hypochondria). This medication is usually given
after other anti-depressants have been tried without successful treatment of symptoms.
Phenelzine is not for treating severe depression or bipolar disorder (manic depression).
Phenelzine may also be used for purposes other than those listed in this medication guide.
