Check out this link at the FDA website. Apparently skin numbing products can be bad for certain individuals. Our clinic just had an overhaul of policies regarding lidocaine cream. We're not supposed to use plastic wrap any more and instead use gauze. And seeing that gauze will not protect your clothing from getting shmeared, they ask that you use the packet that the gauze came in , to cover the area. Plastic wrap doesn't allow your skin to breath and can increase your body temp in that particular area, which is bad, apparently.
There have been reported cases of patients having irregular heartbeats, cardiac arrest, difficulty breathing and worse.
I usually leave the cream on an hour before treatment and in the open air. I only seal the area with a small taped portion of plastic wrap and only when I'm leaving do I even tape it on. I totally understand the concern. So far the clinic that I go to does not mandate the policy. For now it is just a suggestion.
I know one thing though. If the FDA decides to pull EMLA off the shelves, I'll have to change the name of this blog. SHEESH.
