<p><strong>Use in Pregnancy</strong>: Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women. Bisoprolol Fumarate and Hydrochlorothiazide should be used during pregnancy only if the potential benefit justifies the risk to the fetus.<br />
<br />
<strong>Use in Nursing Mothers</strong>: Bisoprolol Fumarate alone or in combination with Hydrochlorothiazide has not been studied in nursing mothers. Thiazides are excreted in human breast milk. Small amounts of Bisoprolol Fumarate have been detected in the milk of lactating rats. Because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.</p>
