In these last few days, I squeezed the remaining amounts of Zanfel from a tube I bought several years ago. It worked to reduce the itching and rash from a local PI infection on my leg. Zanfel did the job for me twice before on local PI infections so I definitely got my money’s worth. However, when I bought it, I, like others here, winched at the price and nearly put it back on the shelf. Later on, when I read through the Zanfel patent online, I was planning to try mixing toothpaste with nonoxynol-9, maybe add a little Tide and sand. But I’m glad to hear that cheaper generic versions of Zanfel are now available. Seems like the various generic versions lack the nonoxynol-9, but it’s pretty easy to add that in, and see if it really makes such a difference. (PS: Thanks vauron for posting your experiment findings.)
You can also ask your doctor about prescribing an antihistamine which might help with the itching so that you do not scratch or pick at the blisters. Hydrogen Peroxide can also be used to keep the blistered area clean and germ free which will then also help the healing process along.
Conceal the area from the sun while it is healing, but make sure that it can still breathe and is kept dry. UV rays have a discoloring effect on scars and can make it look a lot worse than it actually was. Looks are not always all that important, but taking care of yourself and staying healthy is the best medicine for everyone.
