<p>Pregnancy Category C: There are no adequate and well-controlled studies of Trospium in pregnant women. Trospium should be used during pregnancy only if the potential benefit to the patient outweighs the risk to the patient and fetus. Women who become pregnant during Trospium treatment are encouraged to contact their physician.<br />
<br />
Nursing Mothers: Trospium chloride (2 mg/kg orally and 50 mcg/kg intravenously) was excreted, to a limited extent (less than 1%), into the milk of lactating rats (primarily as parent compound). It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, Trospium should be used during lactation only if the potential benefit justifies the potential risk to the newborn.</p>
