APO-ACYCLOVIR OINTMENT is contraindicated for patients who develop hypersensitivity or chemical intolerance to acyclovir, valacyclovir or any of the components of the formulation, such as polyethylene glycol. WARNINGS APO-ACYCLOVIR OINTMENT is intended for topical use only and should not be used in the eye or on mucous membranes, such as the mouth or vagina.
PRECAUTIONS General The recommended dosage, frequency of application and duration of treatment of APO- ACYCLOVIR OINTMENT should not be exceeded (see DOSAGE AND ADMINISTRATION). There exist no data, at this time, which demonstrate that the use of acyclovir ointment will prevent transmission of infection to other persons.
Since most cutaneous herpes simplex virus infections result from reactivation of latent virus, it is unlikely that APO-ACYCLOVIR OINTMENT will prevent recurrence of infections when applied in the absence of signs and symptoms. APO-ACYCLOVIR OINTMENT should not be applied in an attempt to prevent recurrences; application should commence only at the earliest prodromal sign of disease onset.
Although clinically significant viral resistance associated with the use of APO-ACYCLOVIR OINTMENT has not been observed, this possibility exists (see VIROLOGY). Sexual Function/ Reproduction There is no information on the effect of acyclovir oral formulations on human female fertility.
In a study of 20 male patients with normal sperm count, oral acyclovir administered at doses of up to 1 g per day for up to six months has been shown to have no clinically significant effect on sperm count, motility or morphology. Nursing Mothers Acyclovir, when given systemically, is known to be excreted into human milk.
No information is available on levels of acyclovir which may appear in breast milk after administration of APO- ACYCLOVIR OINTMENT and although evidence suggests that absorption of acyclovir through the skin is minimal, caution should be exercised when acyclovir is administered to a nursing mother.
APO-ACYCLOVIR OINTMENT (Acyclovir Ointment) Page 6 of 32 Use in Pregnancy APO-ACYCLOVIR OINTMENT should not be used during pregnancy unless the physician feels the potential benefit justifies the risk of possible harm to the fetus.
Teratology studies using acyclovir cream carried out to date in animals have been negative in general. However, in a non-standard test in rats, there were fetal abnormalities such as head and tail anomalies, and maternal toxicity; and while since such studies are not always predictive of human response, the potential for high concentrations of acyclovir to cause chromosome breaks in vitro should be taken into consideration in making this decision.

All animal studies with the ointment carried out to date on reproduction and teratology have been negative. However, animal reproduction studies are not always predictive of human response. A post-marketing acyclovir pregnancy registry has documented pregnancy outcomes in women exposed to any formulation of acyclovir.
The registry findings have not shown an increase in the number of birth defects amongst acyclovir exposed subjects compared with the general population, and any birth defects showed no uniqueness or consistent pattern to suggest a common cause.
Pediatrics Patients (< 18 years of age) The safe use of acyclovir in pediatric patients less than 18 years of age has not been established DRUG INTERACTIONS Clinical experience has identified no interactions resulting from topical or systemic administration of other drugs concomitantly with acyclovir.
ADVERSE REACTIONS Because ulcerated genital lesions are characteristically tender and sensitive to any contact or manipulation, patients may experience discomfort upon application of acyclovir. There have been very rare reports of immediate hypersensitivity reactions including angioedema with topical acyclovir.
