5.1 Hypersensitivity

Hypersensitivity reactions, including anaphylaxis, angioedema, and urticaria, have been reported with the use of benzoyl peroxide products. If a serious hypersensitivity reaction occurs, discontinue EPSOLAY immediately and initiate appropriate therapy.

5.2 Skin Irritation/Contact Dermatitis

Erythema, scaling, dryness and stinging/burning may be experienced with use of EPSOLAY. Irritation and contact dermatitis may occur. Apply a moisturizer and discontinue EPSOLAY if symptoms do not improve. Avoid application of EPSOLAY to cuts, abrasions, eczematous or sunburned skin.

5.3 Photosensitivity

Benzoyl peroxide may increase sensitivity to sunlight. Minimize or avoid exposure to natural or artificial sunlight (tanning beds or UVA/B treatment) while using EPSOLAY. Instruct the patient to implement sun protection measures (e.g., sunscreen and loose-fitting clothes) when sun exposure cannot be avoided. Discontinue EPSOLAY at the first evidence of sunburn.

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 two randomized, double-blind, vehicle-controlled trials, adult subjects with rosacea applied EPSOLAY (N = 488) or vehicle (N = 234) once daily for 12 weeks. The majority of subjects were Caucasian (93%) and female (73%) with a mean age of 51 years.

Table 1 presents the most common adverse reactions occurring in ≥ 1% of subjects treated with EPSOLAY and more frequently than in subjects treated with vehicle.

During the clinical trials, local tolerability evaluations were conducted at baseline and at each study visit by assessment of dryness, itching, scaling and stinging/burning. Table 2 presents the local tolerability assessments by severity grade at Week 12.

In a 40-week open-label extension safety study (for a total of up to 52 weeks of treatment) the frequency and severity of local tolerability signs and symptoms at Week 52 were comparable to those reported at Week 12.

8.1 Pregnancy

8.2 Lactation

8.4 Pediatric Use

Safety and effectiveness of EPSOLAY for the treatment of inflammatory lesions of rosacea have not been established in pediatric patients.

8.5 Geriatric Use

Of the 733 subjects in the clinical trials of EPSOLAY, 127 (17%) subjects were 65 and over, while 37 (3%) subjects were 75 and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects.

12.1 Mechanism of Action

Benzoyl peroxide is an oxidizing agent with bactericidal and keratolytic effects but the precise mechanism of action in the treatment of rosacea is unknown.

12.2 Pharmacodynamics

The pharmacodynamics of EPSOLAY in the treatment of rosacea are unknown.

12.3 Pharmacokinetics

Benzoyl peroxide is absorbed by the skin where it is converted to benzoic acid, an endogenous substance, which is eliminated in the urine. The systemic exposure of benzoyl peroxide following the application of EPSOLAY was not assessed.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity, mutagenicity, and impairment of fertility studies were not conducted with EPSOLAY.

The role of benzoyl peroxide as a tumor promoter has been well established in several animal species. However, the significance of this finding in humans is unknown.

No significant increase in tumor formation was observed in rats treated topically with a 15 to 25% benzoyl peroxide carbopol gel (3 to 5 times the concentration of benzoyl peroxide in EPSOLAY) for two years. Similar results were obtained in mice topically treated with 25% benzoyl peroxide gel for 56 weeks followed by intermittent treatment with 15% benzoyl peroxide gel for rest of the 2 years study period and in mice topically treated with 5% benzoyl peroxide gel for two years.

Bacterial mutagenicity assays (Ames test) conducted with benzoyl peroxide have provided mixed results; mutagenic potential was observed in a few studies but not in a majority of investigations. Benzoyl peroxide has been found to cause DNA strand breaks in a variety of mammalian cell types and to cause sister chromatid exchanges in Chinese hamster ovary cells.

Fertility studies were not conducted with benzoyl peroxide.

Hypersensitivity

Inform patients that serious hypersensitivity reactions occurred with the use of benzoyl peroxide products. If a patient experiences a serious hypersensitivity reaction, instruct patient to discontinue EPSOLAY immediately and seek medical help [see Warnings and Precautions (5.1)].

Skin Irritation/Contact Dermatitis

Inform patients that EPSOLAY may cause irritation such as erythema, scaling, dryness, stinging or burning. Advise the patient to use a moisturizer for irritation [see Warnings and Precautions (5.2)].

Photosensitivity

Advise patients to minimize or avoid exposure to natural or artificial light (tanning beds or UVA/B treatment) and to use sun protective measures, if patients need to be outdoors while using EPSOLAY [see Warnings and Precautions (5.3)].

Administration Instructions

Advise patients to apply EPSOLAY exactly as directed in a thin layer, avoiding the eyes, lips and mouth and to wash hands immediately after application. Inform patients that EPSOLAY may bleach hair or colored fabric [see Dosage and Administration (2)].
