Tylenol 8-Hour Side Effects in Breastfeeding

A maculopapular rash on the upper trunk and face of a 2-month-old infant was probably caused by Tylenol 8-Hour in breastmilk. The rash occurred after 2 days of therapy in the mother at a dose of 1 gram at bedtime. It subsided when the drug was discontinued and recurred 2 weeks later after another Tylenol 8-Hour dose of 1 gram was taken by the mother.[4] Two papers report 14 women who breastfed after taking Tylenol 8-Hour or its prodrug phenacetin with no adverse effects to their infants.[1][5] In a telephone follow-up study, mothers reported no side effects among 43 infants exposed to Tylenol 8-Hour in breastmilk.[6] Two clinicians speculated that breastmilk exposure to Tylenol 8-Hour during breastfeeding might be a risk factor for asthma and wheezing in the breastfed infants based on their personal observations.[7] However, these observations were uncontrolled and cannot be considered to be valid proof of an association.[8]
