Possible Effects on Lactation
Published information on the effects of guanfacine on serum prolactin or on lactation in nursing mothers was not found as of the revision date. Guanfacine decreases basal serum prolactin in men and nonnursing women. Serum prolactin continues to decrease for at least 7 years during continuous use. The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
