Use in pregnancy: Systemic administration of acyclovir in internationally accepted standard tests did not produce embryotoxic or teratogenic effects in rats, rabbits or mice.
In a non-standard test in rats, fetal abnormalities were observed, but only following such high SC doses that maternal toxicity was produced. Experience in humans is limited, so Vivir Cream should be used by a pregnant woman or possibly pregnant woman only when the expected.
Use in lactation: Contraindicated in lactation.
