Eflornithine topical Pregnancy Warnings

Use is not recommended.

AU TGA pregnancy category: B3
US FDA pregnancy category: C

Comments: Women who are pregnant or planning to become pregnant should use alternative therapy to manage facial hair.

Animal studies (in which no precautions were taken to prevent ingestion of drug from application sites) have revealed evidence of fetal adverse effects at doses that also produced maternal toxicity, including reduced number of live fetuses, decreased fetal weights, delayed ossification and development of the viscera. When the study was repeated under conditions that avoided ingestion from application sites, no maternal, fetal, or teratogenic effects were observed at higher doses. There are no controlled data in human pregnancy.

AU TGA pregnancy category B3: Drugs which have been taken by only a limited number of pregnant women and women of childbearing age, without an increase in the frequency of malformation or other direct or indirect harmful effects on the human fetus having been observed. Studies in animals have shown evidence of an increased occurrence of fetal damage, the significance of which is considered uncertain in humans.

US FDA pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
