Shingles is a skin rash that is characterized by blistering and pain. It is caused by acute infection and is contagious. However, it will cause chicken pox in others, not shingles.The Lidoderm patch is a local anesthetic that soothes shingles pain by preventing the nerves from sending the brain painful impulses.
The Lidoderm patch should be applied on dry and clean skin. It should not be placed upon skin that is damaged, inflamed or broken. You should place the patch on top of the painful part of the skin. It can be worn for a maximum of 12 hours. If you experience any type of burning or irritation upon application of the Lidoderm patch, take it off immediately.
