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.
Directly rubbing a fresh clove of garlic onto the cold sore 2-3 times daily may help to speed up the healing process by three to five days. Just beware of the smell! 1  An alternative is to take a garlic supplement twice a day. 2  Begin by taking 1000 mg a day, before increasing your dosage.
