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 amitriptyline/chlordiazepoxide outweigh the risks.
Family and caregivers must closely watch patients who take amitriptyline/chlordiazepoxide. 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.
Amitriptyline/chlordiazepoxide is not approved for use in children. Talk with the doctor.
Amitriptyline/chlordiazepoxide is used for:
Treating moderate to severe depression with moderate to severe anxiety. It may also be used for other conditions as determined by your doctor.
Amitriptyline/chlordiazepoxide is a combination tricyclic antidepressant and benzodiazepine. How tricyclic antidepressants improve depression symptoms is not fully known. They are thought to increase the activity of certain chemicals in the brain (norepinephrine, serotonin), which help improve mood. The benzodiazepine works in the brain to decrease anxiety.

- you are allergic to any ingredient in amitriptyline/chlordiazepoxide, to other tricyclic antidepressants (eg, nortriptyline), or to other benzodiazepines (eg, diazepam)
- you have acute narrow-angle glaucoma, severe liver disease, or severe mental problems (psychosis)
- you have taken linezolid or a monoamine oxidase inhibitor (MAOI) (eg, phenelzine, selegiline) within the last 14 days
