-The maximum recommended dose in patients who are poor CYP450 2D6 metabolizers is 10 mg per day.
-The dose should be reduced by one-half in patients taking a CYP450 2D6 strong inhibitor (e.g., bupropion, fluoxetine, paroxetine, or quinidine) concomitantly. When the CYP450 2D6 inhibitor is discontinued, the dose may be increased to the original level.
-The dose should be increased when a strong CYP450 inducer (e.g., rifampin, carbamazepine, or phenytoin) is coadministered for greater than 14 days. This maximum dose should not exceed 3 times the original dose. When the inducer is discontinued, the dose of this drug should be reduced to the original level within 14 days.


-Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term studies. These studies did not show an increase in the risk of suicidal thoughts and behavior with antidepressant use in patients over age 24; there was a trend toward reduced risk with antidepressant use in patients aged 65 and older.
-In patients of all ages who are started on antidepressant therapy, monitor closely for worsening, and for emergence of suicidal thoughts and behaviors. Advise families and caregivers of the need for close observation and communication with the prescriber.
