What is zovirax best used for?
As has been stated a true cold sore, or fever blister, is indeed of the Herpes family. But it is not the same as genital herpes. Zovirax is trademark for the first ever anti-viral treatment product. It reputedly is most effective at an earl stage of a cold sore before it ‘breaks out’ and can shorten the lifespan of the outbreak. But it cannot cure the disease and further outbreaks could occur as once the virus is in your blood stream you have it in perpetuity. You remain infectious for some time AFTER signs of the sore have disappeared — so you should be careful that you do not spread it. Once a sore has cleared up, after about three weeks you will no longer be a risk to others. There are other things you can do in terms of improving your immunity and health to reduce the likelihood of further outbreaks, that are natural and non-drug methods.
