Before use, clean the affected area, rinse well, and pat dry. Make sure the area is dry before using this medication. Using a cotton swab to avoid staining your hands, apply gentian violet to the affected area, usually once or twice a day or as directed by your doctor. Apply only to the affected area, and avoid surrounding healthy skin.
Wash hands immediately after use unless the area being treated includes the hands. Avoid getting the product in your eyes. If the medication gets into your eyes, rinse the area immediately with clean water for at least 15 minutes. Seek medical attention if your eye becomes irritated.
This product is for use on the outside of the body only. Do not apply inside the mouth, nose, or ears unless directed by your doctor. This medication is a dye and will stain skin and clothing. Do not apply to open sores (skin ulcers). This may cause permanent "tattooing" of the skin.
