What should I watch for while using this medicine?
Visit your doctor or health care professional for regular checks on your progress. It can take several days before you feel the full effect of this medicine. If you have been taking this medicine regularly for some time, do not suddenly stop taking it. You must gradually reduce the dose or you may get severe side effects. Ask your doctor or health care professional for advice. Even after you stop taking this medicine it can still affect your body for several days.
Patients and their families should watch out for worsening depression or thoughts of suicide.

If this happens, especially at the beginning of antidepressant treatment or after a change in dose, call your health care professional.
