Infertility
Based on findings in rodents, therapy may impair fertility in males of reproductive potential; not known whether effects on fertility are reversible
Animal data
In animal reproduction studies, oral administration of tinidazole to pregnant mice and rats during organogenesis at 6 and 3 times, respectively, the maximum recommended human dose (based on body surface area comparison) showed a slight increase in fetal mortality in rats at highest dose, with no other adverse fetal effects noted in either species
Lactation
