Re: Carcinogenics & Lidocaine. Dee

[Guest guest]

Hi Dee:

I know what you mean and appreciate your response because I do feel

the exact same way. However, my concern is more over the long-term

use of lidocaine, and the frequency with which it is used.

Interesting that you mention that you couldn't find lidocaine

mentioned as a carcinogen because it is right in the package insert

prescribing information for the medication printed by the

pharmaceutical company itself. What happens is with the use of

lidocaine or any " caine " medication, derivatives called anilines

circulate in the body, and these are what are considered

carcinogens. We do have to be careful about such products as our

toothpastes, etc., but these products are generally only of concern

to fringe groups who don't have much science to back them up. With

drugs, the FDA requires so much research before approval that I do

find it disconcerting when the package insert itself lists the

medication as a carcinogen. But it is true that there are many

medications used on the market today that are also potential

carcinogens. I just think it is important to have all the

information in order to make a good decision about which risks we

want to take and which we don't.

Be Well. JR

> I share your concern 'somewhat', but what's amazing is so much of

what we use daily even our toothpaste, mouth washes, and douches,

has some of those ingredients listed as carcinogenic and to me, it

has to be taken in stride somewhat unless we know the whole

picture... You'd be amazed what's listed in the government forms as

being carcinogenic, besides things as estrogen, progesterone, even

oral contraceptives, Alcoholic Beverage Consumption, Chloroform,

Cysplatin, Cyclosporin A, Tamoxifen, even Metronidazole,(drugs often

needed) Mineral oils, Tobacco Smoking, ultraviolet light whether by

sun or artificial.

> Others listed are: IQ, or 2-amino-3-methylimidazo[4,5-f]quinoline,

which is formed during direct cooking with high heat of foods such as

meats and eggs. Another is :

> 2,2-bis-(Bromomethyl)-1,3-propanediol (technical grade), a flame

retardant chemical used to make some polyester resins fire proof.

Methyleugenol, occurs naturally in oils, herbs and spices is another

one. I just think we have to be careful to not go overboard with

some of those reports.... it's always benefit vs. risk with anything

even aspirin. (which 'may' be listed as I think of it , LOL nah not

yet anyway. haha )

> A report on carcinogenics I have says this about the report and

ironically it says

> Relevant information on carcinogenics includes, but is 'not'

limited or known to dose response, route of exposure, chemical

structure, metabolism, pharmacokinetics, sensitive sub populations,

genetic effects, or other data relating to mechanism of action or

factors that may be unique to a given substance.

> For example, there may be substances for which there is evidence of

carcinogenicity in laboratory animals but there are 'no' compelling

data indicating that the agent acts through mechanisms which do 'not'

operate in humans and would therefore ''not'' reasonably be

anticipated to cause cancer in humans. (yet still can be listed)

>

> The carcinogenic report does not assess the magnitude of the

carcinogenic risk, 'nor' does it address any 'potential benefits' of

listed substances such as certain pharmaceuticals. Listing in the

report does 'not' establish that such substance presents a risk to

any persons in their daily lives. Such formal risk assessments are

the responsibility of Federal, State, and local health regulatory

agencies and not this report.

*sigh* but I didn't see LIdocaine listed anywhere in that whole list

I have of listed carcinogenics. ; )
