Several factors can reactivate the virus and cause new sores:
- Emotional or physical stress
- Exposure to sunlight or UV rays
- Hormonal shifts, such as those during menstruation or pregnancy
- Other illnesses, including colds and fevers
- Weakened immune system, due to medical treatments or health conditions
How Are Cold Sores Treated?
There’s no permanent cure for cold sores, but treatments can help manage symptoms and speed up healing:
1. Antiviral pills: Medications like acyclovir, valacyclovir, or famciclovir can reduce the length and severity of an outbreak, especially if taken early.
2. Topical antiviral creams: Help ease symptoms and may reduce viral spread.
3. Pain relievers: Over-the-counter medications like ibuprofen or acetaminophen, or numbing creams, can help relieve discomfort.
4. Moisturizing balms or creams: Soothing lip products can reduce dryness and ease pain around the sores.
