I have a 10 yr old son that has high liver enzymes..he has ADHD and in the last 10 months has been on vyvanse..he was diagnosed at the age of 3 with ADHD and was on stratera for 5 yrs,and when we switched his meds to adderall xr ( was on it for 2 yrs) is when we found out his liver enzymes were high..his highest was 185 and his lowest was 60..we have been to a ped.GI and have had a liver biopsy done.. All they can figure out is that it s an unknown liver disease..they have tested for EVERYTHING...My son weighs 49 pounds and is 4 foot tall..we are curently waiting on more labs on all growth hormones (pituitary glands) and on his chromizomes.. My son needs his ADHD meds but his regular doc s want to wait a month n retest his emzymes before putting him back on it....But I can t wait that long...What else can a person test for to get answers on the high liver enzymes? He is on high calorie diet and the vyvanse breaks down in the kidnies....
