- 2 DOSAGE AND ADMINISTRATION
Acyclovir Cream should be applied 5 times per day for 4 days. Therapy should be initiated as early as possible following the onset of signs or symptoms of herpes labialis, i.e. during the prodrome or when lesions appear.
For adolescents 12 years of age and older, the dosage is the same as in adults.Close
- 3 DOSAGE FORMS AND STRENGTHS
Each gram of Acyclovir Cream 5% contains 50 mg of acyclovir.Close
Acyclovir Cream is contraindicated in patients with known hypersensitivity to acyclovir, valacyclovir, or any component of the formulation.Close
- 5 WARNINGS AND PRECAUTIONS
Acyclovir Cream should only be applied on the affected external aspects of the lips and face in patients with herpes labialis. Because no data are available, application to human mucous membranes is not recommended. Acyclovir Cream is intended for cutaneous use only and should not be used in the eye or inside the mouth or nose.
5.2 Contact Sensitization
Acyclovir Cream has a potential for irritation and contact sensitization [see Adverse Reactions (6.1)].
The effect of Acyclovir Cream has not been established in immunocompromised patients.
- 6 ADVERSE REACTIONS
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug, and may not reflect the rates observed in practice.
In five double-blind, placebo-controlled trials, 1124 patients were treated with Acyclovir Cream and 1161 with placebo (vehicle) cream. Local application site reactions were reported by 5% of patients receiving Acyclovir Cream and 4% of patients receiving placebo. The most common adverse reactions at the site of topical application were dry lips, desquamation, dryness of skin, cracked lips, burning skin, pruritus, flakiness of skin, and stinging on skin; each adverse reaction occurred in less than 1% of patients receiving Acyclovir Cream and placebo. Three patients on Acyclovir Cream and one patient on placebo discontinued treatment due to an adverse event.
An additional study, enrolling 22 healthy adults, was conducted to evaluate the dermal tolerance of Acyclovir Cream compared with vehicle using single occluded and semi-occluded patch testing methodology. Both Acyclovir Cream and placebo showed a high and cumulative irritation potential. Another study, enrolling 251 healthy adults, was conducted to evaluate the contact sensitization potential of Acyclovir Cream using repeat insult patch testing methodology. Of 202 evaluable subjects, possible cutaneous sensitization reactions were observed in the same 4 (2%) subjects with both Acyclovir Cream and placebo, and these reactions to both Acyclovir Cream and placebo were confirmed in 3 subjects upon rechallenge. The sensitizing ingredient(s) has not been identified.
The safety profile in patients 12 to 17 years of age was similar to that observed in adults.
6.2 Postmarketing Experience
In addition to adverse events reported from clinical trials, the following events have been identified during postapproval use of acyclovir cream. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These events have been chosen for inclusion due to a combination of their seriousness, frequency of reporting, or potential causal connection to acyclovir cream.
General: Angioedema, anaphylaxis.
Skin: Contact dermatitis, eczema.
- 7 DRUG INTERACTIONS
Clinical experience has identified no interactions resulting from topical or systemic administration of other drugs concomitantly with Acyclovir Cream. Due to minimal systemic absorption of Acyclovir Cream, systemic drug interactions are unlikely.Close
- 8 USE IN SPECIFIC POPULATIONS
Pregnancy Category B.
There are no adequate and well-controlled studies of acyclovir cream in pregnant women. Acyclovir cream should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
8.3 Nursing Mothers
It is not known whether topically applied acyclovir is excreted in breast milk. Systemic exposure following topical administration is minimal.
However, after oral administration of Acyclovir, acyclovir concentrations have been documented in breast milk in two women and ranged from 0.6 to 4.1 times the corresponding plasma levels. These concentrations would potentially expose the nursing infant to a dose of acyclovir up to 0.3 mg/kg/day. Nursing mothers who have active herpetic lesions near or on the breast should avoid nursing.
8.4 Pediatric Use
An open-label, uncontrolled trial with Acyclovir Cream was conducted in 113 patients aged 12 to 17 years with recurrent herpes labialis. In this trial, therapy was applied using the same dosing regimen as in adults and subjects were followed for adverse events. The safety profile was similar to that observed in adults. Safety and effectiveness in pediatric patients less than 12 years of age have not been established.
8.5 Geriatric Use
Clinical studies of acyclovir cream did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. Systemic absorption of acyclovir after topical administration is minimal [see Clinical Pharmacology (12.3)].

- 12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Acyclovir is an antiviral drug active against herpes simplex virus [see Microbiology (12.4)].
A clinical pharmacology study was performed with Acyclovir Cream in adult volunteers to evaluate the percutaneous absorption of acyclovir. In this study, which included 6 male volunteers, the cream was applied to an area of 710 cm2 on the backs of the volunteers 5 times daily at intervals of 2 hours for a total of 4 days. The weight of cream applied and urinary excretion of acyclovir were measured daily. Plasma concentration of acyclovir was assayed 1 hour after the final application. The average daily urinary excretion of acyclovir was approximately 0.04% of the daily applied dose. Plasma acyclovir concentrations were below the limit of detection (0.01 μM) in 5 subjects and barely detectable (0.014 μM) in 1 subject. Systemic absorption of acyclovir from Acyclovir Cream is minimal in adults.
The systemic absorption of acyclovir following topical application of cream has not been evaluated in patients <18 years of age.
Mechanism of Action: Acyclovir is a synthetic purine nucleoside analogue with cell culture and in vivo inhibitory activity against HSV types 1 (HSV-1) and 2 (HSV-2).
The inhibitory activity of acyclovir is highly selective due to its affinity for the enzyme thymidine kinase (TK) encoded by HSV. This viral enzyme converts acyclovir into acyclovir monophosphate, a nucleotide analogue. The monophosphate is further converted into diphosphate by cellular guanylate kinase and into triphosphate by a number of cellular enzymes. In cell culture, acyclovir triphosphate stops replication of herpes viral DNA. This inhibition is accomplished in 3 ways: 1) competitive inhibition of viral DNA polymerase, 2) incorporation into and termination of the growing viral DNA chain, and 3) inactivation of the viral DNA polymerase.
Antiviral Activity: The quantitative relationship between the cell culture susceptibility of herpes viruses to antivirals and the clinical response to therapy has not been established in humans, and virus sensitivity testing has not been standardized. Sensitivity testing results, expressed as the concentration of drug required to inhibit by 50% the growth of virus in cell culture (EC50), vary greatly depending upon a number of factors. Using plaque-reduction assays, the EC50 values against herpes simplex virus isolates range from 0.09 to 59.9 μM (0.02 to 13.5 μg/mL) for HSV-1 and from 0.04 to 44.0 μM (0.01 to 9.9 μg/mL) for HSV-2.
Drug Resistance: Resistance of HSV to acyclovir can result from qualitative and quantitative changes in the viral TK and/or DNA polymerase. Clinical isolates of HSV with reduced susceptibility to acyclovir have been recovered from immunocompromised patients, especially with advanced HIV infection. While most of the acyclovir-resistant mutants isolated thus far from immunocompromised patients have been found to be TK-deficient mutants, other mutants involving the viral TK gene (TK partial and TK altered) and DNA polymerase have been isolated. TK-negative mutants may cause severe disease in infants and immunocompromised adults. The possibility of viral resistance to acyclovir should be considered in patients who show poor clinical response during therapy.
- 13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Systemic exposure following topical administration of acyclovir is minimal. Dermal carcinogenicity studies were not conducted. Results from the studies of carcinogenesis, mutagenesis and fertility are not included in the full prescribing information for Acyclovir Cream due to the minimal exposures of acyclovir that result from dermal application. Information on these studies is available in the full prescribing information for Acyclovir Capsules, Tablets, and Suspension and Acyclovir for Injection.
- 14 CLINICAL STUDIES
14.1 Adult Subjects
Acyclovir Cream was evaluated in two double-blind, randomized, placebo (vehicle)-controlled trials for the treatment of recurrent herpes labialis. The average patient had five episodes of herpes labialis in the previous 12 months. In the first trial, the median age of subjects was 37 years (range 18 to 81 years), 74% were female, and 94% were Caucasian. In the second trial, median age of subjects was 38 years (range 18 to 87 years), 73% were female, and 94% were Caucasian. Subjects were instructed to initiate treatment within 1 hour of noticing signs or symptoms and continue treatment for 4 days, with application of study medication 5 times per day. In both studies, the mean duration of the recurrent herpes labialis episode was approximately one-half day shorter in the subjects treated with Acyclovir Cream (n = 682) compared with subjects treated with placebo (n = 703) for approximately 4.5 days versus 5 days, respectively. No significant difference was observed between subjects receiving Acyclovir Cream or placebo in the prevention of progression of cold sore lesions.
14.2 Pediatric Subjects
An open-label, uncontrolled trial with Acyclovir Cream was conducted in 113 patients aged 12 to 17 years with recurrent herpes labialis. In this trial, therapy was applied using the same dosing regimen as in adults and subjects were followed for adverse events. The safety profile was similar to that observed in adults.
