Neosporin and Herpes
by Confused207, Apr 05, 2008
Hi.  I feel silly asking this.  Does neosporin make a herpes blister go away quicker?  My bf has HSV 1 (genital).  I have tested negative for both 1 and 2.  We haven't had sex and when we fool around, he wears a condom.  About a week ago, I noticed what felt like a tiny paper cut in my genitals.  I looked in a mirror and didn't see anything.  It didn't look red or irritated, so I put Neosporin on it.  It seemed to go away almost immediately after putting the neosporin on it.  I've been driving myself crazy wondering if it was an outbreak or not.  On a side note, I started working out pretty intensely about 2 months ago.  When I first started, my legs were extremely sore and it felt like the lymph nodes in my groin were swollen.  The swelling has lasted pretty consistently with my training and only recently have seemed to go back to normal.  I just attributed it to overdoing it, but now am wondering if it might be HSV.  If this is nothing to worry about, I've read that it can be transmitted by skin-to-skin contact.  Does that mean that if he's sleeping next to me and we're touching, I could get it, or would it have to be a more frictional type contact??  Thank you for your help!!
The causes of herpes, both genital (usually HSV-2) and oral (always HSV-1), are viruses.  No virus is inhibited by neosporin or any other antibiotics.  By definition, antibiotics are active only against bacteria and some fungi and parasites, not viruses.

The moisturizing effect of the other ingredients in Neosporin (or in any other ointment or cream) might make an oral herpes lesion feel better sooner, but they have no effect whatsoever on speed of healing and do not reduce the amount of virus in the lesion.  In any case, no herpes lesion can go away in less than a week and it's usually 10-14 days before healing is complete.

Therefore, the rapid improvement of the sore in your genital area is pretty good evidence against herpes as the cause.  None of your other symptoms suggest herpes.  Further, most people with genital herpes due to HSV-1 do not have frequent recurrences, and most probably have relatively little asymptomatic viral shedding.  I have never seen a case of genital HSV-1 acquired by genital sex; every case I ever heard of was acquired by oral sex.  Genital-genital HSV-1 infection probably occurs, but probably is rare.

So my bet is that you do not have genital herpes.  But if more typical herpes symptoms appear, or if the cut-like lesion reappears, to be safe you should immediately see a provider for diagnosis (before putting Neosporin or anything else on it).

I hope this helps.  Best wishes--    HHH, MD
