good chance you can reduce the dose but uncertain if you can go off 30% of ADHD patients have another diagnosis in addition
Comes down to do you have depression secondary to living with untreated ADHD, or are you one of the 30% who have anxiety or depression in addition to ADHD. If the former, you might well get off antidepressants but if the latter, then perhaps not.
From a practical point of view, many people are able to reduce the doses of antidepressant - which reduces side effects.
If someone is already on a high dose of antidepressant, we may want to reduce the dose simply because adding a stimulant can raise the blood level of the antidepressant and risk serious side effects.
