Reserve concomitant prescribing of these drugs for patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation.The use of benzodiazepines, including amitriptyline/chlordiazepoxide, exposes users to risks of abuse, misuse, and addiction, which can lead to overdose or death.

Before prescribing amitriptyline / chlordiazepoxide and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction.The continued use of benzodiazepines, including amitriptyline / chlordiazepoxide, may lead to clinically significant physical dependence. The risks of dependence and withdrawal increase with longer treatment duration and higher daily dose.

To reduce the risk of withdrawal reactions, use a gradual taper to discontinue amitriptyline / chlordiazepoxide or reduce the dosage.Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric and young adult patients in short-term studies. Closely monitor all antidepressant-treated patients for clinical worsening, and for emergence of suicidal thoughts and behaviors.
