My son is 13 and just started on Vyvanse about 2 weeks ago. First dose of 50mg and was on for 5 days and nothing seems to change so dr uped it to 60 mg. Been on for 3 days now and my son seems to think it may be working a little bit but I have not seen a whole lot of change. How long before I should see changes?? My dr told me immediately. THis is the first time I have had to deal with any of this so I am not sure what to do or expect. His appetite has def decreased but not much else has changed. Dr said this med is one that goes in system 1hr after taking and should last about 10-12 hrs and out of system till the next day when taken. He said it is not one that has a build up in system. Confused at all of it!!! Please help!!! Any input would be appreciated.
