[|Human|] Hi, my sons diagnosed with ADD and Aspergers.  Hes been taking Vyvanse for about a year now.  Hell be 9 in a couple weeks.  He was started at 20mg but over time has been increased to 50mg.  It seems to work pretty well, but a few months ago the dr. added Strattera in addition to this.  We still supervise and assist with his tooth brushing in the morning and at night but his teeth are turning more and more yellow.  At his last dental checkup about 4 mos ago, they said they werent concerned.  In fact, they said his teeth were in great shape.  But I think theyve gotten more yellow since then.Hes never had soft drinks, and drinks only water, milk, fruit juices and an occasional lemonade.  Could one of these medicines (or their interraction with each other) be causing this yellowing.  Im afraid this is permanent.  Is this reversible?  What can we do?    Thank you for any help you may be able to provide.-- Sheryl
