Hi Sandra,
There are a few things that you can do to prevent cold sores, firstly make sure you are eating healthy and getting enough of the right vitamins. If you have a low immune system you can get tablets to supplement this as a low immune system means you are more likely to get cold sores. Finally if you find that you are getting
cold sores too often then you may need to visit your GP who may have to prescribe some medicine for you.
