DRUG INTERACTIONS
Carcinogenesis, Mutagenesis, Impairment of Fertility
Studies with Zn-DTPA to evaluate carcinogenesis, mutagenesis and impairment of fertility have not been performed. Data for Zn-DTPA effects on spermatogenesis are not available.
Teratogenic Effects
Pregnancy Category B
There are no human pregnancy outcome data from which to assess the risk of Zn-DTPA exposure on fetal development. Reproduction studies have been performed in pregnant mice at doses up to 11.5 mmol/kg (31 times the recommended daily dose of 1 gram based on body surface area [BSA] adjusted dose) and have revealed no evidence of impaired fertility or harm to the fetus. There was a slight reduction in the average birth weight.
Treatment of pregnant women should begin and continue with Zn-DTPA. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. The risk of toxicity from untreated internal radioactive contamination should be weighed against the risk of Zn-DTPA treatment.
