How should I take gentian violet?

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.

Do not cover the area with plastic or waterproof bandages. Covering the area may increase the risk of skin irritation.

If your doctor has prescribed this medication for areas in the mouth, you/your child must be careful to avoid swallowing the medication. If you have any questions about proper use, ask your health care professional.

Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time(s) each day. If your doctor has prescribed this medication, continue to use it until the full prescribed amount is finished, even if symptoms improve after a few days.
