Pregnancy: There are no adequate and controlled studies to date using fexofenadine in pregnant women, and fexofenadine hydrochloride should be used during pregnancy only when the potential benefits justify the possible risks to the fetus.
Lactation: Since there are no adequate and controlled studies to date on the use of fexofenadine during lactation in humans and because many drugs are excreted in human milk, fexofenadine should be used with caution in nursing women, and a decision should be made whether to discontinue nursing or the drug.
