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.
Part 1 Preventing Cold Sores. 1. Avoid cold sore triggers. There are a variety of things that can cause cold sores and it's a good idea to be extra vigilant during cold season. Even stress and lack of sleep can cause cold sores, so try to get a good night's sleep. If you come down with a cold, fever or flu, your risk of an outbreak may increase, as I mentioned, because your immune system is compromised. Make sure you're getting all your necessary vitamins, and plenty of them.
