What is the most important information I should know about amitriptyline? |
|
| While you are taking amitriptyline you may need to be monitored for worsening symptoms of
depression and/or suicidal thoughts at the start of therapy or when doses are changed. This concern
about the increased risk of suicidal thoughts or behaviors may be greater if you are 18 years of age or
younger and are taking amitriptyline. In patients younger than 18 years, the period of risk may extend
beyond start of therapy or when doses are changed. Your doctor may want you to monitor for the
following symptoms: anxiety, panic attacks, difficulty sleeping, irritability, hostility, impulsivity, severe
restlessness, and mania (mental and/or physical hyperactivity). These symptoms may be associated with
the development of worsening symptoms of depression and/or suicidal thoughts or actions. Contact
your healthcare provider if you develop any new or worsening mental health symptoms during treatment
with amitriptyline. Do not stop taking amitriptyline. |
 | It may be 4 weeks or more before you start to feel better, but do not stop taking
amitriptyline without first talking to your doctor. |
|
 | Use caution when driving, operating machinery, or performing other hazardous activities.
Amitriptyline may cause drowsiness or dizziness. If you experience drowsiness or dizziness, avoid these
activities. |
|
| Dizziness is likely to occur when you rise from a sitting or lying position. Rise slowly to
prevent dizziness and a possible fall. |
|
 | Use alcohol cautiously. Alcohol may increase drowsiness and dizziness while you are taking
amitriptyline. |
|
|
