Sodium Sulfacetamide Lotion is indicated in the topical treatment of acne vulgaris .

Sodium Sulfacetamide Lotion is contraindicated for use by patients having known hypersensitivity to sulfonamides or any other component of this preparation (see WARNINGS ).

Fatalities have occurred, although rarely, due to severe reactions to sulfonamides including Stevens-Johnson syndrome, toxic epidermal necrolysis, fulminant hepatic necrosis, agranulocytosis, aplastic anemia, and other blood dyscrasias. Hypersensitivity reactions may occur when a sulfonamide is readministered, irrespective of the route of administration. Sensitivity reactions have been reported in individuals with no prior history of sulfonamide hypersensitivity.

At the first sign of hypersensitivity, skin rash, or other reactions, discontinue use of this preparation (see ADVERSE REACTIONS ). Sodium Sulfacetamide Lotion contains sodium metabisulfite, a sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low.

Sulfite sensitivity is seen more frequently in asthmatic than in non-asthmatic people (see CONTRAINDICATIONS ).

Animal reproduction studies have not been conducted with Sodium Sulfacetamide Lotion. It is also not known whether Sodium Sulfacetamide Lotion can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Sodium Sulfacetamide Lotion should be given to a pregnant woman only if clearly needed. Kernicterus may occur in the newborn as a result of treatment of a pregnant woman at term with orally administered sulfonamide.
