Drug Levels and Effects
Summary of Use during Lactation
Xanomeline is a cholinergic antipsychotic agent that is available in combination with trospium, which is a peripheral anticholinergic agent. No information is available on the clinical use of xanomeline or trospium during breastfeeding. Because trospium is a charged molecule, it is unlikely to pass well into milk. If the mother requires xanomeline, it is not a reason to discontinue breastfeeding. Until more data are available, the xanomeline-trospium combination should only be used with careful infant monitoring, particularly for gastrointestinal side effects such as nausea, vomiting diarrhea, and reflux.
