When I added in Allopurinol with my 6mp I had to stop my 6mp for a week to get my 6mp levels down - because Allopurinol and 6mp (at the regular dosing) is not recommended. So I told my doc that I was nervous about stopping the 6mp for a week. He told me that it takes approximately 6-10 weeks for it to completely leave your system.
