Rizatriptan Breastfeeding Warnings

There are no data on the excretion of rizatriptan into human milk. Because many drugs are excreted into human milk, caution is advised when considering the use of rizatriptan in a nursing woman.

The manufacturer has reported that rizatriptan is extensively excreted in rat milk, at a level five or more times maternal plasma levels.
