Visit your doctor or health care professional for regular checks on your progress. Even though you may start to feel better, continued treatment may be needed to keep your symptoms under control.
Patients and their families should watch out for worsening depression or thoughts of suicide. Also watch out for any sudden or severe changes in feelings such as feeling anxious, agitated, panicky, irritable, hostile, aggressive, impulsive, severely restless, overly excited and hyperactive, or not being able to sleep. If this happens, especially at the beginning of treatment or after a change in dose, call your doctor.
