Home remedies for cold sores include putting a cold, wet towel around the mouth for 20 minutes, three times a day; rinsing the mouth with baking powder and avoiding acidic foods, such as tomatoes and citric fruits, explains WebMD. Nonprescription ointments and medications may also relieve symptoms of cold sores.
Aspirin, ibuprofen and acetaminophen may alleviate pain, according to WebMD. However, aspirin should not be given to people under 20 years, because this may lead to Reye's syndrome. Abreva and Zilactin can stimulate healing and prevent the sores from extending to other parts if administered early. Orajel and Anbesol may soothe the sores, but the patient should consult a doctor prior to using these medicines.
Those with cold sores should limit the time they spend in sunlight, use a lip balm sunscreen to protect the lips from the sun and keep their faces away from direct sunlight, advises WebMD. Avoiding intimate contact, including kissing, and sharing items, such as towels, with those with cold sores may help prevent transference.
To control cold sores in children, make them wash hands regularly, clean toys with disinfectant and use disposable gloves to apply medicated ointment to the sores, notes WebMD. Children with this complication should not share toys with the ones free of the disease, while children with open cold sore blisters should stay at home until the blisters dry.
