<p><strong>Pregnancy:</strong>&nbsp;Propafenone has been assigned to&nbsp;pregnancy category C by the FDA.&nbsp;There are no controlled data in human&nbsp;pregnancy. Limited data indicate that&nbsp;propafenone has been administered&nbsp;during the third trimester of pregnancy&nbsp;without adverse maternal or fetal&nbsp;effects. Propafenone should be given&nbsp;during pregnancy only when benefit&nbsp;outweighs risk.<br />

<strong>Nursing Mothers:</strong>&nbsp;It is not known whether this drug is&nbsp;excreted in human milk. Because many&nbsp;drugs are excreted in human milk and&nbsp;because of the potential for serious&nbsp;adverse reactions in nursing infants&nbsp;from propafenone, a decision should be&nbsp;made whether to discontinue nursing or&nbsp;to discontinue the drug, taking into&nbsp;account the importance of the drug to&nbsp;the mother.</p>
