Paracetamol is generally considered to be the analgesic of choice in pregnant patients. However, the frequent use of paracetamol (defined as most days or daily use) in late pregnancy may be associated with an increased risk of persistent wheezing in the infant which may persist into childhood.
No adverse effects have been seen in breastfed infants whose mothers were receiving paracetamol. The amount of paracetamol distributed into breast milk is too small to be harmful to a breast-fed infant.
