What is the most important information I should know about Nefazodone hydrochloride?

Antidepressant medicines may increase suicidal thoughts or actions in some children, teenagers, and young adults when the medicine is first started. Depression and other serious mental illnesses are the most important causes of suicidal thoughts and actions. Some people may have a particularly high risk of having suicidal thoughts or actions. These include people who have (or have a family history of) bipolar disorder (also called manic-depressive illness) or suicidal thoughts or actions.

Pay close attention to any changes, especially sudden ones, in mood, behaviors, thoughts, or feelings. This is very important when an antidepressant medicine is first started or when the dose is changed.

Call the doctor right away to report new or sudden changes in mood, behavior, thoughts, or feelings. Signs to watch for include new or worsening depression, new or worsening anxiety, agitation, insomnia, hostility, panic attacks, restlessness, extreme hyperactivity, and suicidal thinking or behavior.

Keep all follow-up visits as scheduled, and call the doctor between visits as needed, especially if you have concerns about symptoms.
