Healing a Cold Sore: Effective Treatments for Every Stage

Antiviral Therapy

• Topical: Acyclovir or penciclovir cream applied 5 times daily at first sign.
• Oral: Acyclovir, valacyclovir, or famciclovir (prescription) shorten duration by 1–2 days if started early.

Symptom Relief

• Cold compress: Apply ice wrapped in cloth for 10–15 minutes to reduce pain and swelling.
• Moisturize: Use petroleum jelly or a lip balm with zinc oxide to prevent cracking and secondary infection.
• Pain relievers: OTC ibuprofen or acetaminophen for discomfort.

Critical Do's and Don'ts

• Don't pick, squeeze, or touch the sore—spreads virus and delays healing.
• Don't share drinks, utensils, towels, or lip products.
• Do wash hands after applying medication.
• Do support immunity: rest, hydrate, eat nutritious foods.

Most cold sores heal within 7–10 days. See a doctor if sores spread near eyes, persist beyond two weeks, or you have a weakened immune system.
