@timothy.mountcastle: A patient in Canada reportedly died after excessive topical lidocaine was applied before a cosmetic procedure. Let’s be clear. It wasn’t microneedling. It was too much numbing cream, over too large an area, left on too long. Topical lidocaine peaks in the bloodstream about 1–2 hours after application. Surface area changes systemic absorption. Timing changes systemic absorption. This is pharmacology. Not drama. When used correctly with proper protocols and physician oversight, topical lidocaine is very safe. If your provider can’t explain the pharmacokinetics, that’s the red flag. #medspa #MedSpaSafety #Microneedling #AestheticMedicine #northernvirginia

I used to cover my entire legs with lidocaine and cover them with Saran Wrap for laser hair removal. Did I mess up my liver or my body doing that?

What do you recommend removing the lidocaine with? Alcohol wipe or just soap and water?

My mentor always told me you should never apply more than the size of a sheet of paper

I don’t even think it’s necessary for microneedling. If you can’t handle a little discomfort then you don’t want results bad enough

I’ve personally seen lidocaine toxicity in the surgical setting and we had intralipids available- I can’t imagine how scary this would be in a Medspa/clinic setting, and the potential delay in care dt people being unable to recognize it.

I hate that most of my healthcare and med related info comes from TikTok. Equally I’m grateful for medical professionals spreading info and awareness to everyone, esp younger audiences. 👏Thank you doctor 👏

My sister had methemoglobinemia from lidocaine. Good/fast paramedics and a smart ER doctor who administered methylene blue saved her life. It’s rare, but something I had no idea about.

thoughts on occluding topical lidocaine with plastic wrap? I've seen some people swear by this and others say it's dangerous

This isn’t talked about enough! I’m an RN at a med spa and this is part of my consult. I discuss max surface area treatment due to lidocaine use.

In my medspa we use a BLT combination (benzocaine, lidocaine, and tetracaine) would something like this be potentially more dangerous than lidocaine alone? We do have a standard small amount that we can dispense per our policy pre procedure.

I’m only learning about this today cause of that death case. I’ve gotten 4 sessions of microneedling and have 2 more coming up. All 4 times I’ve been numbed but the professional I go to is always so anal about not leaving it on after a certain amount of time. Didn’t know why, just assumed the cream hit its “peak” numbing. Yikes. Now I know I’m in good hands with mine

This was with a 20+% strength correct? Was the surface area larger than the face and neck?
