Pregnancy & Lactation
Pregnancy
There are insufficient data regarding use in pregnancy to evaluate for a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes
Severe hypertension can result in maternal stroke, pulmonary edema, myocardial ischemia or death of the mother or fetus
Animal data
- In animal studies, there was no evidence of teratogenicity or fetotoxicity when fenoldopam was orally administered to rats and rabbits during organogenesis; there are adverse effects on maternal and fetal outcomes associated with severe hypertension
Lactation
There are no data on presence of drug in human milk, effects on breastfed child, or on milk production; drug is present in rat milk; when a drug is present in animal milk, it is likely that the drug will be present in human milk
Because of potential for severe adverse reactions in breastfed infant, advise women not to breastfeed during treatment
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
