Drug Levels and Effects

Summary of Use during Lactation

No data are available on sucralfate use during breastfeeding; however, it is virtually unabsorbed orally. Most authorities consider sucralfate acceptable to use during breastfeeding.[1-4] No special precautions are required, including following application to the nipples in a skin cream.

Effects on Lactation and Breastmilk

A study of mother with cracked nipples compared the effects of soft paraffin (petrolatum) (n = 47) to a commercial cream containing sucralfate, zinc and copper (Cicalfate-Avene, France) (n = 68). Reduction of nipple cracking judged by a blinded dermatologist was 3.3 to 5.3 times greater in the sucralfate group compared to the petrolatum group.[5]
