I’ve made a new best friend in the form of an anaesthetic cream (LMX) with 4% lidocaine. We get on really well together but I don’t want to abuse our relationship.
Do you think it might be harmful if I empty all 5gms (containing 40mg lidocaine/1g cream) of it onto an area of my skin?
Hope everyones well.
The risk of poisoning increases with a high dose of a single type of substance. It is safer to combine the same amount in two different types of anesthetics used one twice.
Body weight and age of the person is a required to prescribe the right dose.
The deaths that have happened give us a clue. Don’t cover your entire legs and genital area with anesthetic, and then wrap it all up with plastic wrap and then spend 2 hours with it soaking in your skin.
Hi:
I think the problems happened with specially compounded topicals of a much higher concentration than either Emla or L-M-X applied over extremely large areas.
A 30 gm tube of Emla costs about 50 bucks, so unless you are independently wealthy you should probably only use a limited amount for one session. If anyone is buying the 5gm tubes they are probably paying more per gm than if they bought the larger 30gm tube.

I am 9 and 3/4 stones in weight, and I am in my early 30s. Will 5gms put me in any danger?
Hi two:
I don’t think 5 mg is dangerous. I’ve used several times that before some sessions if I was covering a larger area.
The problems in the past have been with some of the specially compounded topicals which are much higher concentrations than these over the counter types.

I second the motion. 5 mg is nowhere near dangerous. Even on mucus membrane tissue, the worst reaction you could have would be temporary constipation.
attention!!!
(Lidocaine 40 mg / 1 g cream)
5 gms is 200 mg.
In mucus area the maximum dose is 300 mg and the exposure time maximum 15/30 minutes.
thanx 4 the replies. Yes, by 5 gms I meant 5 grammes rather than 5 milligrammes. Maybe theres a difference in abbreviations across the pond.
I had very little idea about any deaths caused by lidocaine, as it is available so freely and with little warning. So I shall need to do some more research on it. I might try going on their website.
With 30min exposure I would have to arrive at the clinic early and apply it there. But probably not a good idea to smear it all over at home and then travel with it under the scorching summer sun anyway.
Hi:
As mentioned before, the deaths were attributed to specially compounded topicals of higher strength stuff as per the following thread.

The goop was spread over extremely large areas, such as the complete legs.
