Antiviral medications can help them heal faster if taken early. Talk to your doctor if your cold sores do not go away after two weeks. Helpful? 1 person found this helpful.
Cold sores cannot be treated with antibiotics because they are caused by a virus. However, using nonprescription ointments can help reduce the pain associated with a cold sore and may even help heal the cold sore. Common products used to reduce the duration of a cold sore include Abreve and Zilactin.
