In reply to Nortriptyline dosage ??? - One more question. » Psydoc, posted by SLS on March 24, 2002, at 7:44:27
The conventional wisdom is that nortriptyline is most effective as an antidepressant when the blood level is between 50 and 150 ng/ml. The actual situation is more compex with some people responding optimally to lower levels and others requiring blood levels higher than the usually stated range.
When the blood level is higher than what is optimal for an individual, depression is likely to increase. I am not aware that the depression that happens in the presence of a high blood level is different from the depression for which the nortriptyline was originally prescribed.
Sometimes when the blood level is too high the clinical picture is complicated by CNS side-effects such as forgetfulness.
Best regards . . .
