About Klaron

Klaron is a prescription topical medication containing sodium sulfacetamide, which belongs to a class of drugs known as sulfonamide antibiotics. It is indicated for the local treatment of acne vulgaris, a skin condition involving the formation of pimples and inflamed lesions. By slowing or stopping the growth of bacteria that contribute to acne development, this lotion helps to clear the skin and reduce the overall number of breakouts when used consistently as prescribed. Patients should be aware that because it is a sulfa-based drug, it is not suitable for individuals with a known sensitivity to sulfonamides. Following a healthcare provider's instructions regarding frequency and application technique is essential for achieving the best therapeutic outcomes.

Prescribing information

From the FDA-approved label for Klaron. Official source: DailyMed (NLM) · Label effective Aug 31, 2020

Indications and usage

INDICATIONS Klaron Lotion is indicated in the topical treatment of acne vulgaris .

Dosage and administration

DOSAGE AND ADMINISTRATION Apply a thin film to affected areas twice daily.

Contraindications

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

Warnings

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 ). Klaron 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 ).

Adverse reactions

ADVERSE REACTIONS In controlled clinical trials for the management of acne vulgaris , the occurrence of adverse reactions associated with the use of Klaron Lotion was infrequent and restricted to local events. The total incidence of adverse reactions reported in these studies was less than 2%. Only one of 105 patients treated with Klaron Lotion had adverse reactions of erythema, itching, and edema. It has been reported that sodium sulfacetamide may cause local irritation, stinging, and burning. While the irritation may be transient, occasionally the use of medication has to be discontinued. To report SUSPECTED ADVERSE REACTIONS, contact Bausch Health US, LLC at 1-800-321-4576 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
