How long does lidocaine stay in breast milk?

Understanding Lidocaine in Breast Milk
Lidocaine, a widely used local anesthetic, raises important questions regarding its safety for breastfeeding mothers and their infants. When administered, lidocaine does pass into breast milk, but the concentrations and potential effects on breastfeeding infants are critical factors to consider.
Concentration Levels in Breast Milk
Research indicates that lidocaine concentrations in breast milk are relatively low. For instance, after administration, the average concentration of lidocaine in breast milk is about 120.5 mcg/L at three hours post-dose, decreasing to 58.3 mcg/L by six hours. This suggests that while lidocaine does transfer into breast milk, the amounts are not substantial.
Moreover, studies have shown that lidocaine levels in breast milk can be approximately 40% of the serum levels in the mother. This means that even if a mother receives a significant dose of lidocaine, the amount that reaches the infant through breastfeeding is considerably reduced.
Safety for Breastfed Infants
The consensus among medical professionals is that lidocaine is not expected to cause adverse effects in breastfed infants. The low absorption rate of lidocaine in infants further supports this view. Additionally, the pharmacokinetics of lidocaine suggest that it is rapidly metabolized, which minimizes the risk of accumulation in the infant’s system.
Recommendations for Use
While lidocaine is generally considered safe during breastfeeding, it is always advisable for mothers to consult with their healthcare providers regarding its use. This is particularly important if the mother is undergoing procedures that require local anesthesia or if she has concerns about the effects on her infant.
In summary, while lidocaine does enter breast milk, the concentrations are low and unlikely to harm breastfeeding infants. Mothers should feel reassured but should always seek personalized medical advice to ensure the best outcomes for both themselves and their children.

Drug Levels
Milk MEGX levels were 97.5 and 52.7 mcg/L at 3 and 6 hours after the dose, respectively. [11] Using the average daily intake reported in this study, an exclusively breastfed infant would receive 0.9% of the maternal weight-adjusted dosage of lidocaine and another 0.8% in the form of the metabolite MEGX.
