Whatís New in Cold Sores (herpes simplex)

Cold Sores (herpes simplex)

Cold sores (ie, herpes simplex, usually type 1) are common, painful, and socially embarrassing. Thankfully, treatment of recurrent cold sores on the lip has become shorter. Rather than the older traditional ~1 week of treatment, it has become accepted that one day of treatment is effective. However, this is true only if treatment is begun as soon as possible. If the HSV-1 virus is allowed to increase in number by delaying treatment even after symptoms are noticed (burning, tingling) or the rash (blisters, sores) is noticed, then the peak viral replication phase may have passed (the first eight hours after symptoms are noticed) and treatment may not be as effective.

In addition, it has become more accepted that valacyclovir is preferred over traditional acyclovir due to greater absorption into the bloodstream.

While I hope that some day there will be a cure for this vexing condition, improvements on our treatment is always appreciated. If you suffer from cold sores, or have other questions, I look forward to seeing you. Please make an appointment for a dermatology consultation at (626) 331-6411.
