Atorvastatin Pregnancy Warnings

Animal studies have failed to reveal evidence of teratogenicity, however, doses of 20, 100, or 225 mg/kg/day given to rats from day 7 of gestation through day 21 of weaning resulted in decreased pup survival at birth, developmental delays, pinnae detachment, and eye opening alterations. Rare cases of congenital anomalies following intrauterine exposure to HMG-CoA reductase inhibitors have been reported. There are no controlled data in human pregnancy. Serum cholesterol and triglycerides increase during normal pregnancy, and cholesterol products are essential for fetal development. Since atherosclerosis is a chronic process, discontinuation of lipid-lowering drugs during pregnancy should have little impact on long term outcomes of primary hypercholesterolemia therapy. AU TGA pregnancy category D: Drugs which have caused, are suspected to have caused or may be expected to cause, an increased incidence of human fetal malformations or irreversible damage. These drugs may also have adverse pharmacological effects. Accompanying texts should be consulted for further details. US FDA pregnancy category X: Studies in animals or humans have demonstrated fetal abnormalities and/or there is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience, and the risks involved in use of the drug in pregnant women clearly outweigh potential benefits.
