Lindane topical Pregnancy Warnings

This drug should be used during pregnancy only if clearly needed.

US FDA pregnancy category: C

Comments: This drug is lipophilic and may accumulate in the placenta.

There are no controlled data in human pregnancy; however, there is a single case report of a stillborn infant following multiple maternal exposures to this drug during pregnancy. The relationship of the maternal exposures to the fetal outcome is unknown. Animal data suggest this drug may increase the likelihood of neurologic developmental abnormalities, based on findings at systemic exposures close to that expected 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.
