Many nutritionists suggest that the amino acid L-lysine should be given at the first sign of a cold sore and until it resolves to limit the severity and duration of the virus. Vitamin C , bioflavonoids and vitamin E all have anti-inflammatory properties and are helpful in treating cold sores. Taking Care As a preventative measure, keep the child's lips moisturized and protected from sun wind, and cold. Try a lip balm with an SPF of at least 15. Minimize your child's contact with children who have an active infection of herpes simplex.
Cold sores are contagious.
If anyone in the family has an active cold sore, avoid kissing children or sharing bath linens, drinking glasses, eating utensils, or anything that touches the cold sore. Everyone should wash their hands frequently with soap and water. If the child develops cold sores, explain the importance of not touching or picking at the cold sore. Monitor the child carefully and be particularly vigilant that they avoid putting their hands near their eyes after touching the cold sore. Herpes simplex infection in the eyes can be extremely serious.
