Gentian violet treats yeast and fungal infections. These include Candida albicans, also called thrush, which affects the mouth of infants and can also cause nipple pain for the mother if she is infected by her child. In the case of thrush, both mother and child need to be treated simultaneously.
Use
Gentian violet is a topical solution. You paint the gentian violet onto the affected area with a cotton swap two or three times a day for three days, according to MayoClinic.com. If using gentian violet in the mouth, do not swallow it or let your child swallow it.
Side Effects
Most people don't experience side effects when using gentian violet, though some people may get a rash or have an allergic reaction. If this happens, stop using gentian violet and consult your doctor. Some babies get sores after gentian violet is applied in their mouth, but these usually clear up within 24 hours, according to KeepKidsHealthy.com.
Safety
Gentian violet is safe for most people to use. However, people with porphyria should avoid using gentian violet. If you have open sores, avoid using gentian violet, since it may cause tattooing of the area. Do not swallow this medicine, as it is not safe to take it internally.
Considerations
Gentian violet can be quite messy. Although it sometimes can be washed out, it often stains clothing. It will temporarily turn the area being treated purple, but the purple color fades shortly after treatment. You shouldn't cover up the treated area with airtight bandages, as this irritates the skin.
