Will Lipitor pass into breastmilk?
Lipitor (atorvastatin) is a statin medication used to lower cholesterol levels in the blood. It is a pregnancy category X drug, meaning it is contraindicated in pregnant women [1].
When it comes to breastfeeding, there is limited information available on the effects of Lipitor on milk production. However, one study suggested that atorvastatin is present in breastmilk in small amounts, but the amount does not seem to affect infant growth or development [2].
However, the study also noted that long-term effects of exposure to atorvastatin in infants are unknown [3].
Will Lipitor affect milk supply?
While there is limited information on the specific effect of Lipitor on milk supply, statins in general can potentially affect lactation. Some studies have reported a decrease in milk production in breastfeeding women taking statins [4][5].
Who should avoid Lipitor while breastfeeding?
If you are taking Lipitor and breastfeeding, it is recommended that you discuss the potential risks and benefits of continuing the medication with your healthcare provider. They can help you weigh the risks of the medication against the benefits and make an informed decision [6].
However, if you are experiencing any of the following symptoms, you should contact your healthcare provider:
- Reduced milk production
- Abnormal infant behavior
- Abnormal infant growth
Timeline: When can I see effects?
The effects of Lipitor on milk production are not well-studied, and it is unclear when you might see any changes. However, if you are taking statins and experiencing a decrease in milk production, it is recommended that you discuss the issue with your healthcare provider [7].
