Prevention
If you have fever blisters frequently, your doctor might suggest an antiviral drug to take on a regular basis. In case sunlight would trigger these sores, it is advisable to apply sunblock. Since this is a contagious condition, some preventive measures should be taken to prevent it from spreading to other people. Avoid skin-to-skin contact with those with clear blisters. Similarly, do not share items, such as lip balm, towels, razors, or utensils. Lastly, wash your hands thoroughly before touching other people. [8]
