I contracted HSV in 1998 didn’t know what it was until 2001 when I was diagnosed it would breakout every summer on back of my left leg. Some years went by somehow transmitted it to my forehead it would breakout look like I hit my head on something one big puffy red spot. New dermatologist prescribed Valacyclovir 1500mg 3 times a day for 3 days during outbreak. When I would stop taking it start to come back again. They had me take one 500 MG a day it worked I would go though the winter try to stop taking it last a few weeks for month start breaking out again. I asked the doctor if Valtrex has a rebound they told me it doesn’t. I had been taking valacyclovir for about 5 years and I noticed I felt foggy headed just didn’t feel right didn’t like the idea of taking a pill everyday. I started searching again online about rebound this time I found some research that Valacyclovir does have rebound effect. So I started to taper off I would get down to 1/4 pill every few days then I was able to stop it completely. During this time I found a new GP he tested me for low vitamin he found I was low on B-12 and D. I took both of those and it’s been almost 2 years since I quit taking Valacyclovir haven’t had one breakout even though 2 summers. I think with the combo of low B-12 low D my immune system was not good after I boosted the B-12 and took the D I felt much better not having to take Valtrex every day.
