Use in pregnancy: Pregnancy Category C: There are no adequate and well-controlled studies in pregnant women. Ganciclovir should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Use in lactation: It is not known whether topical ophthalmic ganciclovir administration could result in sufficient systemic absorption to produce detectable quantities in breast milk. Caution should be exercised when ganciclovir is administered to nursing mothers.
