About one year ago, I had an outbreak of cold sores. I took Famvir immediately, which seemed to work. Famvir is pill that you take as soon as you see the cold sores appear. My doctor gave me extra prescriptions for Famvir.
Unfortunately, recently, about a year later, I had another outbreak of cold sores. I tried to find the Famvir prescription but I had lost it. Instead I purchased Zovirax, which is a cream you apply to the cold sore to treat it.
The bottom line is that Zovirax seems to work, but the package and the internet say that you cannot swallow Zovirax. This is completely unreasonable because cold sore almost always break out on your lips or near your lips. If you apply Zovirax to your lips to treat cold sores, you will eventually swallow the cream when you eat, drink, or sleep.
I will ask my doctor for prescriptions of Famvir so I don't need to use Zovirax (or Blistex or similar cold sore creams) when I have a cold sore outbreak again.
