Table of contents:

Klaron lotion is a prescription medication used to treat acne, seborrheic dermatitis, and other scaly skin conditions caused by bacteria. It contains the active ingredient sulfacetamide sodium. Sodium sulfacetamide belongs to a class of drugs known as sulfa antibiotics. The lotion works by preventing bacteria from growing and multiplying, which helps to lower skin inflammation.

Use and Dosage

Klaron lotion is usually applied topically to the affected skin areas once or twice a day, or as directed by a healthcare provider.

To use Klaron Lotion, shake the container well before each use and with clean hands, apply a thin film of the lotion to the areas of skin with acne, usually twice daily or as directed by your doctor. Be sure to wash your hands with soap and water after each use to avoid getting the medication in your eyes, nose, or mouth.

Use the lotion regularly for the best results, but avoid using large amounts, using it more often, or using it for a longer time than prescribed. If your acne does not improve after a few weeks, tell your doctor. Stop using this medication and contact your doctor right away if your acne worsens or if you experience a rash or any other serious side effects. Note that Klaron Lotion is intended for use on the skin only.
