Sibutramine Levels and Effects while Breastfeeding
Summary of Use during Lactation
Sibutramine is no longer marketed in the United States. Because there is no published experience with sibutramine during breastfeeding, an alternate therapy may be preferred, especially while nursing a newborn or preterm infant. Information on the effect of sibutramine on serum prolactin is somewhat conflicting.

Effects on Lactation and Breastmilk
In a study of hypocaloric diet plus sibutramine in overweight and obese patients with polycystic ovary syndrome, no change was seen in serum prolactin levels over the 6-month study period.[1]
A woman developed amenorrhea-galactorrhea syndrome shortly after starting therapy with sibutramine for weight loss. Her serum prolactin was elevated, but returned to normal within 15 days of discontinuing sibutramine. It remained in the normal range during the 180-day follow-up period.[2]
The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
