A cold sore is a fluid-filled blister — or a group of blisters — that typically develops around the lips. It’s caused by the herpes simplex virus, which is typically passed from skin-to-skin contact. To manage cold sores:

Stop the spread — Avoid touching the sore, as that can make it worse and lead to spread. Refrain from kissing or other direct contact. Wash your hands regularly. Don’t share food, beverages, towels, lip balms or razors with others. Throw away toothbrushes you used while you had the cold sore.

Treat it early — The nonprescription antiviral cream docosanol (Abreva) may reduce symptoms and shorten recovery time. Docosanol is most effective if used when you first notice tingling or other early signs that indicate a cold sore is forming.

Control the pain — A pain reliever such as acetaminophen (Tylenol, others) or ibuprofen (Advil, Motrin IB, others) may
help. Nonprescription cold sore gels or ointments containing benzocaine, lidocaine or benzyl alcohol also can relieve
symptoms. Applying a cool compress or sucking on ice chips may help minimize burning or itching. Dabbing petroleum jelly on the sore and surrounding skin helps reduce dryness and cracking.

Get a prescription — See your primary care physician or a dermatologist if a cold sore lasts for two weeks or keeps recurring. You may be eligible for treatment with an antiviral cream or pill. Antiviral drugs may take hours or even days off your recovery time.

Know the causes — Triggers that may “wake up” the herpes virus to cause cold sores include stress, becoming ill with a cold or the flu, exposure to sunlight or strong winds, changes in the immune system, or hormonal changes.
