📄 Full prescribing information FDA SPL
🎯 Indications and Usage ▾
INDICATIONS AND USAGE Acyclovir Ointment USP, 5% is indicated in the management of initial genital herpes and in limited non-life-threatening mucocutaneous HSV infections in immunocompromised patients.
⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION Apply sufficient quantity to adequately cover all lesions every 3 hours, 6 times per day for 7 days. The dose size per application will vary depending upon the total lesion area but should approximate a one-half inch ribbon of ointment per 4 square inches of surface area. A finger cot or rubber glove should be used when applying Acyclovir Ointment USP, 5% to prevent autoinoculation of other body sites and transmission of infection to other persons.
Therapy should be initiated as early as possible following onset of signs and symptoms.
⛔ Contraindications ▾
CONTRAINDICATIONS Acyclovir Ointment USP, 5% is contraindicated in patients who develop hypersensitivity to the components of the formulation.
⚠️ Warnings ▾
WARNINGS Acyclovir Ointment USP, 5% is intended for cutaneous use only and should not be used in the eye.
🤒 Adverse Reactions ▾
ADVERSE REACTIONS In the controlled clinical trials, mild pain (including transient burning and stinging) was reported by about 30% of patients in both the active and placebo arms; treatment was discontinued in 2 of these patients. Local pruritus occurred in 4% of these patients. In all studies, there was no significant difference between the drug and placebo group in the rate or type of reported adverse reactions nor were there any differences in abnormal clinical laboratory findings.
Observed During Clinical Practice: Based on clinical practice experience in patients treated with Acyclovir Ointment USP, 5% in the US, spontaneously reported adverse events are uncommon. Data are insufficient to support an estimate of their incidence or to establish causation. These events may also occur as part of the underlying disease process.
Voluntary reports of adverse events that have been received since market introduction include: General: Edema and/or pain at the application site. Skin: Pruritus, rash. To report SUSPECTED ADVERSE REACTIONS, contact Xiromed, LLC. at 844-XIROMED (844-947-6633) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
🔄 Drug Interactions ▾
Drug Interactions: Clinical experience has identified no interactions resulting from topical or systemic administration of other drugs concomitantly with Acyclovir Ointment USP, 5%.
🤰 Pregnancy ▾
Pregnancy: Teratogenic Effects: Pregnancy Category B. Acyclovir was not teratogenic in the mouse, rabbit, or rat at exposures greatly in excess of human exposure. There are no adequate and well-controlled studies of systemic acyclovir in pregnant women.
A prospective epidemiologic registry of acyclovir use during pregnancy was established in 1984 and completed in April 1999. There were 749 pregnancies followed in women exposed to systemic acyclovir during the first trimester of pregnancy resulting in 756 outcomes. The occurrence rate of birth defects approximates that found in the general population.
However, the small size of the registry is insufficient to evaluate the risk for less common defects or to permit reliable or definitive conclusions regarding the safety of acyclovir in pregnant women and their developing fetuses. Systemic acyclovir should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
🧒 Pediatric Use ▾
Pediatric Use: Safety and effectiveness in pediatric patients have not been established.
🧓 Geriatric Use ▾
Geriatric Use: Clinical studies of Acyclovir Ointment USP, 5% 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 ).
🆘 Overdosage ▾
OVERDOSAGE Overdosage by topical application of Acyclovir Ointment USP, 5% is unlikely because of limited transcutaneous absorption (see CLINICAL PHARMACOLOGY ).
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY Two clinical pharmacology studies were performed with Acyclovir Ointment USP, 5% in immunocompromised adults at risk of developing mucocutaneous HSV infections or with localized varicella-zoster infections. These studies were designed to evaluate the dermal tolerance, systemic toxicity, and percutaneous absorption of acyclovir. In one of these studies, which included 16 inpatients, the complete ointment or its vehicle were randomly administered in a dose of 1-cm strips (25 mg acyclovir) 4 times a day for 7 days to an intact skin surface area of 4.5 square inches.
No local intolerance, systemic toxicity, or contact dermatitis were observed. In addition, no drug was detected in blood and urine by radioimmunoassay (sensitivity, 0.01 mcg/mL). The other study included 11 patients with localized varicella-zoster infections.
In this uncontrolled study, acyclovir was detected in the blood of 9 patients and in the urine of all patients tested. Acyclovir levels in plasma ranged from <0.01 to 0.28 mcg/mL in 8 patients with normal renal function, and from <0.01 to 0.78 mcg/mL in 1 patient with impaired renal function. Acyclovir excreted in the urine ranged from <0.02% to 9.4% of the daily dose.
Therefore, systemic absorption of acyclovir after topical application is minimal.
