You would have to ask psychiatrist who has expertise in treating ADHD to give the most accurate answer.
Ifr you have ADHD you may also have some depressive symptoms and it would make sense to be on both medications.
Wellbutrin is also (clinical studies)known to effectively manage ADHD symptoms in some patients.
Perhaps your doctor feels that being on both drugs will manage your symptoms better overall.
Ask your doctor?.
