5 Interactions found for:

The following applies to the ingredients: Metoprolol

Professional Content

US: This drug should be used during pregnancy only if clearly needed.
AU and UK: Use is not recommended unless benefit outweighs risk; if used during pregnancy, administer the lowest possible dose and discontinue at least 2 to 3 days prior to expected delivery, if possible.

AU TGA pregnancy category: C
US FDA pregnancy category: C

Animal studies have revealed increased postimplantation loss, fetolethality, and decreased neonatal survival. There are no controlled data in human pregnancy.

AU TGA pregnancy category C: Drugs which, owing to their pharmacological effects, have caused or may be suspected of causing, harmful effects on the human fetus or neonate without causing malformations. These effects may be reversible. Accompanying texts should be consulted for further details.

US FDA pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.

The following applies to the ingredients: Rosuvastatin (found in Crestor)

Professional Content

Contraindicated

AU TGA pregnancy category: D
US FDA pregnancy category: Not assigned

Risk Summary: Safety in pregnant women has not been established and there is no apparent benefit to use during pregnancy. Because HMG-CoA reductase inhibitors (statins) decrease cholesterol synthesis and possibly the synthesis of other biologically active substances derived from cholesterol, this drug may cause fetal harm during pregnancy.

Comments:
-This drug should be discontinued as soon as pregnancy is recognized, and the patient should be apprised of the potential harm to the fetus.
-Women of childbearing potential should use adequate methods of contraception during therapy.

Animal studies have failed to reveal evidence of teratogenicity in doses approximating the maximum human dose of 40 mg/day. Limited published data has not shown an increased risk of major congenital malformations or miscarriage, although there have been rare reports of congenital anomalies following intrauterine exposure to other statins. Several cases of serious fetal abnormalities were reported in 2 series of 178 and 143 cases among pregnant women taking a HMG-CoA reductase inhibitor (statin) during the first trimester of pregnancy. These included limb and neurological defects, spontaneous abortions and fetal deaths. In a review of approximately 100 prospectively followed pregnancies in women exposed to simvastatin or lovastatin, the incidences of congenital anomalies, spontaneous abortions, and fetal deaths/stillbirths did not exceed what would be expected in the general population. 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 hyperlipidemia 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 Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.

Contraindicated

Excreted into human milk: Yes (in low amounts)

Comments:
-Due to the potential for serious adverse events in nursing infants and the concern over disruption of infant lipid metabolism, women who require treatment with this drug should not breastfeed.
