question: 5 years ago I had shingles.  I knew the symptoms and went to the Dr. When symptoms first showed up.  Dr. Put me on Valtrex  (1 GM)and now I have the first symptoms again went to the Dr. And the Dr. Gave me Zovirax.  The Zovirax  800 mg does not seem to be doing as good a job.  Are these two meds very similar and do you think the Zovirax will do the same as the Valtrex did.  I just have a few little pimple looking bumps on my back.  Also should I wait until I take all of the Med before being around anyone pregnant.  We have a girl that has been having difficulties with her pregnancy at church and I surely would not want to harm her baby. Thank you
