Hi Tilly
I get cold sores too and bloody hate them. I always think they look a bit dirty.
I'm sure you know as much as I do about them but these things help me . . .
I reckon prevention is so important because once those tiny blisters pop there is little more that the zovirax can do. I think it is great to use zovirax early, but once it has turned into a cut/sore then I stop using it. Zovirax is a really strong cream and I reckon it would cause a sore on healthy skin if used repeatedly so I have learned when to stop using it.
I try to be very alert to the very first symptoms (tingle on my lip/nose and pain/sensitivity on my scalp) at times when I know a coldsore is likely to start ie when I'm stressed, tired, a change from dull to bright sunlight eg on holidays.
My first line of defence (before using zovirax) is a cold sore machine. Have you tried it? I think the reviews might be mixed about how effective it is but I really think mine helps if I zap it as soon as possible. I bought mine quite a while ago and cant see it online after a quick look this evening, but others seem to cost about £40. Although I don’t remember paying that amount for mine.
Have you ever been prescribed a course of meds from your GP? I was given a course some years ago. If my memory serves it is a course of acyclovir which is the important ingredient in zovirax. It is in tablet form and I think the idea is to help prevent the cold sores from starting starting. I think it is important not to take it if there is any possibility that you may become pregnant though.
Lastly, hopefully you aren’t paying for the full price zovirax? There are lots of alternative cold sore creams nowadays and as long as they have the same amount of acyclovir in them then you may as well buy the much much cheaper versions.
I hope some of that might have helped Tilly – they really are horrible things.
