6 ADVERSE REACTIONS The most common adverse reaction reported in 0.4% of adult patients is stinging. (6.1) The most common adverse reactions reported in 10% of pediatric patients are signs of skin atrophy, telangiectasia, bruising, shininess. (6.1, 8.4) To report SUSPECTED ADVERSE REACTIONS, contact Perrigo at 1-866-634-9120 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 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 clinical practice. In controlled clinical trials, involving 242 adult subjects, the adverse reaction associated with the use of betamethasone dipropionate cream (augmented), 0.05% reported at a frequency of 0.4% was stinging. It occurred in 1 subject. In a controlled clinical trial involving 67 pediatric subjects from 3 months to 12 years of age, the adverse reactions associated with the use of betamethasone dipropionate cream (augmented), 0.05% occurred in 7 of 67 (10%) subjects. Reported reactions included signs of skin atrophy (telangiectasia, bruising, shininess). 6.2 Postmarketing Experience Because adverse reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Postmarketing reports for local adverse reactions to topical corticosteroids may also include: burning, itching, irritation, dryness, folliculitis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, hypertrichosis, skin atrophy, striae, and miliaria. Hypersensitivity reactions, consisting of predominantly skin signs and symptoms, e.g., contact dermatitis, pruritus, bullous dermatitis, and erythematous rash have been reported. Ophthalmic adverse reactions of cataracts, glaucoma, increased intraocular pressure, and central serous chorioretinopathy have been reported with the use of topical corticosteroids, including topical betamethasone products.

4 CONTRAINDICATIONS Betamethasone Dipropionate Cream USP (Augmented), 0.05% is contraindicated in patients who are hypersensitive to betamethasone dipropionate, to other corticosteroids, or to any ingredient in this preparation. Hypersensitivity to any component of this medicine. (4)

1 INDICATIONS AND USAGE Betamethasone Dipropionate Cream USP (Augmented), 0.05% is a corticosteroid indicated for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses in patients 13 years of age or older. Betamethasone Dipropionate Cream USP (Augmented), 0.05% is a corticosteroid indicated for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses in patients 13 years of age and older.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Corticosteroids play a role in cellular signaling, immune function, inflammation, and protein regulation; however, the precise mechanism of action of Betamethasone Dipropionate Cream USP (Augmented), 0.05% in corticosteroid responsive dermatoses is unknown. 12.2 Pharmacodynamics Vasoconstrictor Assay Trials performed with betamethasone dipropionate cream (augmented), 0.05% indicate that it is in the high range of potency as demonstrated in vasoconstrictor trials in healthy subjects when compared with other topical corticosteroids. However, similar blanching scores do not necessarily imply therapeutic equivalence. 12.3 Pharmacokinetics No pharmacokinetics trials have been conducted with Betamethasone Dipropionate Cream USP (Augmented), 0.05%. The extent of percutaneous absorption of topical corticosteroids is determined by many factors including the vehicle, the integrity of the epidermal barrier, and the use of occlusive dressings. Topical corticosteroids can be absorbed through normal intact skin. Inflammation and/or other disease processes in the skin may increase percutaneous absorption. Occlusive dressings substantially increase the percutaneous absorption of topical corticosteroids [ see Dosage and Administration (2) ]. Once absorbed through the skin, topical corticosteroids enter pharmacokinetic pathways similar to systemically administered corticosteroids. Corticosteroids are bound to plasma proteins in varying degrees, are metabolized primarily in the liver, and excreted by the kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile.

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information). Inform patients of the following: Discontinue therapy when control is achieved, unless directed otherwise by the physician. Use no more than 50 grams per week. Avoid contact with the eyes. Advise patients to report any visual symptoms to their healthcare providers. Avoid use of Betamethasone Dipropionate Cream USP (Augmented), 0.05% on the face, underarms, or groin areas unless directed by the physician. Do not occlude the treatment area with bandage or other covering, unless directed by the physician. Note that local reactions and skin atrophy are more likely to occur with occlusive use, prolonged use or use of higher potency corticosteroids. Advise a woman to use Betamethasone Dipropionate Cream USP (Augmented), 0.05% on the smallest area of skin and for the shortest duration possible while pregnant or breastfeeding. Advise breastfeeding women not to apply Betamethasone Dipropionate Cream USP (Augmented), 0.05% directly to the nipple and areola to avoid direct infant exposure.

14 CLINICAL STUDIES The safety and efficacy of betamethasone dipropionate cream (augmented), 0.05% for the treatment of corticosteroid-responsive dermatoses have been established in two randomized and active controlled trials in subjects with chronic plaque psoriasis. A total of 81 subjects who received betamethasone dipropionate cream (augmented), 0.05% were included in these trials. These trials evaluated betamethasone dipropionate cream (augmented), 0.05% applied once or twice daily for 14 and 21 days, respectively, on bilateral paired psoriatic lesions. Betamethasone dipropionate cream (augmented), 0.05% was shown to be effective in relieving the signs and symptoms of chronic plaque psoriasis.

8.5 Geriatric Use Clinical trials of betamethasone dipropionate cream (augmented), 0.05% included 104 subjects who were 65 years of age and over and 8 subjects who were 75 years of age and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients. However, greater sensitivity of some older individuals cannot be ruled out.

8.4 Pediatric Use Use of Betamethasone Dipropionate Cream USP (Augmented), 0.05% in pediatric patients younger than 13 years of age is not recommended due to the potential for HPA axis suppression [ see Warnings and Precautions (5.1) ]. In an open-label HPA axis safety trial in subjects 3 months to 12 years of age with atopic dermatitis, betamethasone dipropionate cream (augmented), 0.05% was applied twice daily for 2 to 3 weeks over a mean body surface area of 58% (range 35% to 95%). In 19 of 60 (32%) evaluable subjects, adrenal suppression was indicated by either a ≤5 mcg/dL pre-stimulation cortisol, or a cosyntropin post-stimulation cortisol ≤18 mcg/dL and/or an increase of <7 mcg/dL from the baseline cortisol. Out of the 19 subjects with HPA axis suppression, 4 subjects were tested 2 weeks after discontinuation of betamethasone dipropionate cream (augmented), 0.05%, and 3 of the 4 (75%) had complete recovery of HPA axis function. The proportion of subjects with adrenal suppression in this trial was progressively greater, the younger the age group. Because of a higher ratio of skin surface area to body mass, pediatric patients are at a greater risk than adults of systemic toxicity when treated with topical drugs. They are, therefore, also at greater risk of HPA axis suppression and adrenal insufficiency upon the use of topical corticosteroids. Rare systemic effects such as Cushing's syndrome, linear growth retardation, delayed weight gain, and intracranial hypertension have been reported in pediatric patients, especially those with prolonged exposure to large doses of high potency topical corticosteroids. Local adverse reactions including skin atrophy have also been reported with use of topical corticosteroids in pediatric patients. Avoid use of Betamethasone Dipropionate Cream USP (Augmented), 0.05% in the treatment of diaper dermatitis.

8.1 Pregnancy Risk Summary There are no available data on Betamethasone Dipropionate Cream USP (Augmented), 0.05% use in pregnant women to identify a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Observational studies suggest an increased risk of low birthweight infants with the use of greater than 300 grams of potent or very potent topical corticosteroid during a pregnancy. Advise pregnant women that Betamethasone Dipropionate Cream USP (Augmented), 0.05% may increase the risk of having a low birthweight infant and to use Betamethasone Dipropionate Cream USP (Augmented), 0.05% on the smallest area of skin and for the shortest duration possible. In animal reproduction studies, increased malformations, including umbilical hernias, cephalocele, and cleft palate, were observed after intramuscular administration of betamethasone dipropionate to pregnant rabbits. The available data do not allow the calculation of relevant comparisons between the systemic exposure of betamethasone dipropionate in animal studies to the systemic exposure that would be expected in humans after topical use of Betamethasone Dipropionate Cream USP (Augmented), 0.05% (see Data). The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data Betamethasone dipropionate has been shown to cause malformations in rabbits when given by the intramuscular route at doses of 0.05 mg/kg. The abnormalities observed included umbilical hernias, cephalocele, and cleft palate.

The abnormalities observed included umbilical hernias, cephalocele, and cleft palate. 8.2 Lactation Risk Summary There are no data regarding the excretion of betamethasone dipropionate in breast milk, the effects on the breastfed infant, or the effects on milk production after topical application of Betamethasone Dipropionate Cream USP (Augmented), 0.05% to women who are breastfeeding. It is possible that topical administration of large amounts of betamethasone dipropionate could result in sufficient systemic absorption to produce detectable quantities in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Betamethasone Dipropionate Cream USP (Augmented), 0.05% and any potential adverse effects on the breastfed infant from Betamethasone Dipropionate Cream USP (Augmented), 0.05% or from the underlying maternal condition. Clinical Considerations To minimize potential exposure to the breastfed infant via breast milk, use Betamethasone Dipropionate Cream USP (Augmented), 0.05% on the smallest area of skin and for the shortest duration possible while breastfeeding. Advise breastfeeding women not to apply Betamethasone Dipropionate Cream USP (Augmented), 0.05% directly to the nipple and areola to avoid direct infant exposure [ see Use in Specific Populations (8.4) ]. 8.4 Pediatric Use Use of Betamethasone Dipropionate Cream USP (Augmented), 0.05% in pediatric patients younger than 13 years of age is not recommended due to the potential for HPA axis suppression [ see Warnings and Precautions (5.1) ].
