Methylergonovine and Milk Supply

With respect to milk supply in women taking methylergonovine, we have found that a single post-partum dose will suppress prolactin levels, but doesn't seem to have much of a noticeable effect on supply. Existing studies are conflicted regarding this drug's effect on milk supply if used for more than a single post-partum dose. Some studies found no effect, others describe a very significant drop in milk production which is reversible on stopping the medication.1-4 No new research has been published on this topic in the last 20 years.
