Fenoprofen Pregnancy Warnings

Fenoprofen has not been formally assigned to a pregnancy category by the FDA. There are no controlled data in human pregnancy. While there are no literature reports linking the use of fenoprofen in pregnancy with birth defects, use late in pregnancy may cause premature closure of the ductus arteriosus and prolong labor and delivery. Fenoprofen is only recommended for use during pregnancy when benefit outweighs risk. Fenoprofen should be avoided near term.

Limited data from one review suggest fenoprofen is not detectable in cord blood or amniotic fluid. Additional study is needed to confirm this finding.

Fenoprofen Lactation Warnings

Fenoprofen is excreted into human milk. The manufacturer recommends that due to the potential for serious adverse reactions in nursing infants, a decision should be made to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

In one study, fenoprofen was undetectable in most milk samples, following administration of fenoprofen 600 mg every six hours for four days. At times when fenoprofen was detectable, the milk to plasma concentration ratio was approximately 0.02.
