Carcinogenesis
Long-term studies in animals to evaluate the carcinogenic potential of hydromorphone have not been conducted.
Mutagenesis
Hydromorphone was not mutagenic in the in vitro bacterial reverse mutation assay (Ames assay). Hydromorphone was not clastogenic in either the in vitro human lymphocyte chromosome aberration assay or the in vivo mouse micronucleus assay.
Impairment of Fertility
No effects on fertility, reproductive performance, or reproductive organ morphology were observed in male or female rats given oral doses up to 7 mg/kg/day which is 2.8 times the human dose of 24 mg hydromorphone hydrochloride injection (4 mg every 4 hours), on a body surface area basis.
