High cholesterol is usually not a problem for women who are in their childbearing years. Concerns with high cholesterol usually come in later years; however it is possible that elevated cholesterol could be a problem you are experiencing. Atorvastatin, also called Lipitor, is one of the more common medications prescribed to help manage high cholesterol.
Atorvastatin use during pregnancy is a valid question. Its use during pregnancy is not recommended because of the potential adverse effects to your baby. Atorvastatin, also called Lipitor, use during pregnancy is a valid question. If you have been taking Lipitor, or atorvastatin, and recently discovered you are pregnant, it is important to consult your health care provider immediately.
Brand Name: Lipitor Manufacturer: Parke-Davis
Therapy with lipid-altering agents should be only one component of multiple risk factor intervention in individuals at significantly increased risk for atherosclerotic vascular disease due to hypercholesterolemia. Drug therapy is recommended as an adjunct to diet when the response to a diet restricted in saturated fat and cholesterol and other non pharmacologic measures alone has been inadequate.
Pregnancy Recommendation: Contraindicated
Pregnancy Safety Rating: Category X
Side Effects to the Mother:
- Common: Atorvastatin is generally well tolerated. Side effects are usually mild and transient.
- Frequent: (16%) Headache
- Occasional: (5%-2%) Myalgia, rash, pruritus, allergy
- Rare: (less than 2%-1%) Flatulence, dyspepsia, depression.
Lifespan Considerations: Pregnancy/Lactation
Distributed in breast milk. Contraindicated during pregnancy. May produce skeletal malformation. Pregnancy: Category X
Briggs, Freeman, & Yaffe – The interruption of cholesterol-lowering therapy during pregnancy should have no effect on long-term treatment of hyperlipidemia. Moreover, because cholesterol and products synthesized by cholesterol are important during fetal development, the use of atorvastatin is contraindicated during pregnancy. However, the absolute embryo risk from inadvertent exposure in the 1st trimester appears to be low.
Physicians’ Desk Reference – Lipitor is contraindicated in women who are or may become pregnant. Serum cholesterol and triglycerides increase during normal pregnancy. Lipid lowering drugs offer no benefit during pregnancy because cholesterol and cholesterol derivatives are needed for normal fetal development. Atherosclerosis is a chronic process, and discontinuation or lipid-lowering drugs during pregnancy should have little impact on long-term outcomes of primary hypercholesterolemia therapy.
There are no adequate and well-controlled studies of atorvastatin use during pregnancy. There have been rare reports of congenital anomalies following intrauterine exposure to statins. In a review of about 100 prospectively followed pregnancies in women exposed to other statins, the incidences of congenital anomalies, spontaneous abortions, and fetal/stillbirths did not exceed the rate expected in the general population. However, this study was only able to exclude a three-to-four increased risk of congenital anomalies over background incidence. In 89% of these cases, drug treatment started before pregnancy and stopped during the first trimester when pregnancy was identified. Atorvastatin crosses the rat placenta and reaches a level in fetal liver equivalent to that of maternal plasma. Atorvastatin was not teratogenic in rats at doses up to 300 mg/kg/day or in rabbits at doses up to 100 mg/kg/day. These doses resulted in multiples of about 30 times (rat) or 20 times (rabbit) the human exposure based on surface area (mg/m2).
In a study in rats given 20, 100, or 225 mg/kg/day, from gestation day 7 through to lactation day 21 (weaning), there was decreased pup survival at birth, neonate, weaning, and maturity in pups of mothers dosed with 225 mg/kg/day. Body weight was decreased on days 4 and 21 in pups of mothers.
Reprotox Toxicology Center – Based on experimental animal studies and a small number of exposed human cases, inadvertent exposure to atorvastatin during early pregnancy appears unlikely to increase the risk of adverse pregnancy outcome. Theoretical considerations concerning the role of cholesterol in embryo development plus the lack of demonstrated benefit of treating hyperlipidemia during gestation argue against intentional use of statins during pregnancy.
