Nardil (Phenelzine)
Patient Information

Pronounced: NAHR-dill
Generic name: Phenelzine sulfate
Why is Nardil prescribed?

Nardil is a monoamine oxidase (MAO) inhibitor used to treat depression as well as anxiety or phobias mixed with depression. MAO is an enzyme responsible for breaking down certain neurotransmitters (chemical messengers) in the brain. By inhibiting MAO, Nardil helps restore more normal mood states. Unfortunately, MAO inhibitors such as Nardil also block MAO activity throughout the body, an action that can have serious, even fatal, side effects--especially if MAO inhibitors are combined with other foods or drugs containing a substance called tyramine.
