Indications and Usage
ACZONE™ Gel, 5%, is indicated for the topical treatment of acne vulgaris.Glucose 6-phosphate dehydrogenase (G6PD) levels should be obtained prior to initiating therapy with ACZONE™ Gel, 5%.  In patients with a history of anemia and predisposition to increased hemolytic effect with dapsone (e.g., glucose-6-phosphate dehydrogenase deficiency), closer follow-up for blood hemoglobin levels and reticulocyte counts should be implemented (see PRECAUTIONS).  Alternatively, other therapies for acne than ACZONE™ Gel, 5%, may be considered.
Acne Vulgaris -- A chronic disorder of the pilosebaceous apparatus associated with an increase in sebum secretion. It is characterized by open comedones (blackheads), closed comedones (whiteheads), and pustular nodules. The cause is unknown, but heredity and age are predisposing factors.

Anemia -- A reduction in the number of circulating erythrocytes or in the quantity of hemoglobin.

Glycogen Storage Disease Type I -- An autosomal recessive disease in which gene expression of glucose-6-phosphatase is absent, resulting in hypoglycemia due to lack of glucose production. Accumulation of glycogen in liver and kidney leads to organomegaly, particularly massive hepatomegaly. Increased concentrations of lactic acid and hyperlipidemia appear in the plasma. Clinical gout often appears in early childhood.

Acne -- chronic inflammatory disease of the pilosebaceous apparatus marked by an increase in sebum secretions causing lesions most frequently occurring on the face, chest, and back; the inflamed glands may form small pink papules, which sometimes surround comedones so that they have black centers (blackheads), or form pustules or cysts (whiteheads).

ACZONE™ Gel, 5%, is contraindicated in persons with a hypersensitivity to dapsone or any other component of the formulation.
Hypersensitivity -- Altered reactivity to an antigen, which can result in pathologic reactions upon subsequent exposure to that particular antigen.
