Cold sores are unattractive and painful, but there are some viable prescription and over-the-counter remedies to help expedite the healing process. In his blog, Dr. Robert G. Tupac, D.D.S., F.A.C.P., suggests using antiviral medications if the cold sore is caught early or if you are prone to them. These medications include acyclovir (Zovirax), famciclovir (Famvir), and valacyclovir (Valtrex) and can be prescribed by your dentist.
Lidocaine and benzocaine (commonly known as Zilactin) are topical ointments that can be purchased at your local drugstore without a prescription. Never use more than the recommended dosage or on children younger than age two without doctor’s direction.
Over-the-counter pain relievers such as aspirin, Tylenol, or Advil help alleviate pain and discomfort. If you choose not to take any type of oral medications, placing ice or a warm compress on the blister may offer some relief. Dr. Tupac stresses that the most important thing to remember about treating cold sores is to let them heal and not squeeze, pinch, or pick at any sore.
If you have a cold sore that will not heal or is causing you significant discomfort, seek treatment from a dental expert immediately.
