Codeine-6-glucuronide (C6G) is a major active metabolite of codeine and may be responsible for as much as 60% of the analgesic effects of codeine. C6G exhibits decreased immunosuppressive effects compared to codeine.{{Cite journal | last1 = Srinivasan | first1 = V. | last2 = Wielbo | first2 = D. | last3 = Tebbett | first3 = I.
