Codeine was not mutagenic while in the in vitro bacterial reverse mutation assay or clastogenic while in the in vitro Chinese hamster ovary (CHO) mobile chromosomal aberration assay. Fertility reports with codeine have not been carried out.
The results of concomitant use or discontinuation of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with codeine are advanced, demanding careful consideration of the effects within the guardian drug, codeine, and the active metabolite, morphine.
