Antidepressants may increase the risk of suicidal thoughts or actions in children, teenagers, and young adults. However, depression and certain other mental problems may also increase the risk of suicide. Talk with the patient's doctor to be sure that the benefits of using Parnate outweigh the risks.
Family and caregivers must closely watch patients who take Parnate. It is important to keep in close contact with the patient's doctor. Tell the doctor right away if the patient has symptoms like worsened depression, suicidal thoughts, or changes in behavior. Discuss any questions with the patient's doctor.
Parnate is not approved for use in children. Talk with the doctor.
Parnate is used for:
Treating depression. It may also be used for other conditions as determined by your doctor.
Parnate is a monoamine oxidase inhibitor (MAOI). It works by blocking the action of the enzyme (monoamine oxidase) that breaks down the body's mood-elevating chemicals (dopamine, norepinephrine, and serotonin). This produces an increase in the activity of these mood-elevating chemicals.
