GERD Home > H2 Blockers and Breastfeeding

Because H2 blockers pass through breast milk in low amounts, many people have questions about H2 blockers and breastfeeding. While it is not known how these low amounts of H2 blockers might affect a growing baby, the risks are probably low, especially since some H2 blockers are approved for use in infants (even newborns). Be sure to talk with your healthcare provider about taking H2 blockers while breastfeeding.

An Overview of H2 Blockers and Breastfeeding

H2 blockers are passed through breast milk in low amounts. The manufacturers of H2 blockers generally suggest that a nursing woman who has been prescribed an H2 blocker either stop breastfeeding or stop taking the H2 blocker.
 
Practically, when healthcare providers are asked about H2 blockers and breastfeeding, they often advise their patients that it is okay to breastfeed while taking these medications. This is because, in many cases, the benefits of breastfeeding a child outweigh the possible risks.
 

What Does the Research Say About H2 Blockers and Breastfeeding?

Studies have shown that H2 blockers are passed through breast milk in relatively low amounts. While it is not known how these low amounts of H2 blockers might affect a growing baby, the risks are probably low, especially since some H2 blockers are approved for use in infants (even newborns). If you are using H2 blockers to treat a more serious condition (such as ulcers), your healthcare provider may recommend taking H2 blockers while breastfeeding. However, if you are taking H2 blockers for a less serious condition (such as indigestion), your healthcare provider may recommend stopping H2 blockers while breastfeeding.
