There are some medications that decrease milk supply, like decongestants (e.g., pseudoephedrine)[1] and certain combined oral contraceptives.[2] These medications are not commonly used in the context of breast engorgement because they could permanently reduce milk production (unless the goal is to halt lactation). Breast engorgement is better managed by effective milk removal coupled with supportive measures to reduce discomfort.
Are there medications that can suppress milk production?

Certain medications — such as decongestants and some combined oral contraceptives — can decrease milk supply but are not typically used for breast engorgement due to the risk of permanently reducing milk production. Effective milk removal and supportive measures are recommended for managing breast engorgement.
